Embedding BI Reports (Jasper Reports/ Jasper Server/ Pentaho Reports/ Pentaho Server)

There are many methods of embedding BI reports, this blog tries to explain the meaning of Embedded BI, different approaches which can be used, their respective advantages and disadvantages

 

A)     What is embedded BI?

Lets say you have developed your entire BI solution which includes reports, dashboards, mashups, analysis etc, the platform which is used can be anything like Jaspersoft or Pentaho. The process of integration of this BI solution with your existing application/software/portal is called Embedded BI.

Embedded BI provides a lot of advantages like ability to add more reports over and above the existing canned reports which your application might provide, the look and feel and customization of all the reports can be changed as per the software/user preference, better visualization, unified application for everything. Biggest advantage can be your product value will increase much more, hence resulting in much more sales and revenue.

a) Embedding using iFrame Method :-

iFrame method of embedding BI reports can be used for embedding Jasper server, Jasper reports and Pentaho server, Pentaho reports. The report pulled in this case is using iframe as a tag. Even though the report is external, but to an end customer he will not be able to recognize the same.

The advantages of using iFrame method is this method is fast and quick to implement. The disadvantages includes it will be difficult to manage user, also in this case there can be cross browser compatibility issues, security is a major issue here.

 

b) Embedding Using webservice:- Webservices can also be used to integrate reports, dashboard, interactive report or/and ad-hoc reports. We can use webservices to accept the information from the Jasper/Pentaho server, this Jasper server can be anywhere ( on Tomcat or any other server). Using webservices we will invoke the response from Jasper Server/Pentaho server. This response can be can be then embedded inside application/software. Jasper server/Pentaho server also supports RESTFUL service (JSON format responses). In this approach there are no or less security related issues.

The disadvantage of this approach is there are no interactive features available of the report which thus results in poor user experience. Also in order to handle and understand the responses from jasper server/Pentaho server, custom coding is required in the application. In case if we had put input controls in the report, the same functionality then needs to be implemented in the application via custom coding. Aside, having many webcalls at times can be resource intensive as well.

The advantage of this approach is webservices approach gives more seamless integration since there is no security issue and no thirdparty calls (like in the case of iframe). Also in this case there are no interbrowser compatibility issues (assuming it is handled by your developer team).

c) Embedding using Jasper/Pentaho Libraries:- In this method we create JRXML/Pentaho report (prpt) files using ireport/Pentaho report designer. Compile these reporting using Java API, and then use this compiled code to generate views using Jasper Server API calls

The advantage of this method is this gives the most seamless integration. Also since all the information is present as a part of the application/server, no third party calls are required.

Disadvantage of this approach is some interactivity is lost in this method. Also the input parameters are also required to be created in the own application via custom coding.

 

Please get in touch at [email protected] for much more details about the respective approach, how to embed the same using these approaches, which was is the best suited to your needs and much more.

Tech Tips in Penaho Server – publishing password setting for server – Disable the folder names in Browser panel in the Server

Hi guys..

The below tips are very useful in Pentaho Server for BI developers.
1) publishing password setting for server
You need to publish the reports or schema(s)[developed in PSW] once you done with developing. For this you need set the publishing password for Pentaho server.
Go to this location 
<location of Pentaho>biserver-ce-4.8.0-stable\biserver-ce\pentaho-solutions\system\publisher-config.xml and edit the “publisher-config.xml”  file.

Give your publish password b/w  these tags  <publisher-password> </publisher-password>

Example:
<publisher-password>password</publisher-password>    ( password can be any name that you wish to give)

Snapshot is a worth more than text. find the image below.

Save the file. stop the server and start the server.

2) Disable the folder names in Browser panel of Pentaho Server
* What ever the folder you create in Browser panel of pentaho server, it directly stores   under pentaho-soulutions
i.,e in this location
<Pentaho location>Pentaho\biserver-ce-4.8.0-stable\biserver-ce\pentaho-solutions
* You can disable all of your folders that comes with installation & the later created ones  which you don’t want to appear in the browser panel.
*   Inside every folder(pentaho default or the folders created by you) you can find “index.xml” file. You need to edit this file. You need to change visable tag as “false”.
Find the sanpshot.

You need not restart the server. Just you need to refresh the browser panel in the server.
You can observer the invisibility of the folder.

Date Input Controls/ Components in Pentaho CDE with a working example

Hello guys…!!!

In this post you will learn about how to create date input controls in CDE.
The dashboard images which I am going to show below are having lots of .css code. I’m not covering all the things but concentrating only on Date input controls in CDE.

My Environment :
BI Server: Pentaho 4.5
CTools: Not found the version numbers of  C-Tools(Unable to check them)– perhaps..! lesser than 13
Database : hsqldb (Comes along with Pentaho installation — A java based small db for servers like pentaho)
NOTE: Images are taken in this post after creating the dashboard, please find the yellow rectangular boxes to understand.

You need to work out @ 3 places in “Components” section.
1. Generic
2. Selects
3. Charts
Explained from step 1 to step 3
You need to work out  @ 1 places in “Data Sources” section. i.e, all in “Properties”
I’m not concentrating on Layout part for this example. So wherever the HtmlObject you find in this example replace them with your working HtmlObjects.

Step 1: Creating parameters
* Design your dashboard as per your requirement ( In the images you can find the sample designs).
 In the “Components” section:
1. Click on components
2. Click on Generic
3. Click on Date parameter
4. Go to properties give the name
eg: param_start_date
5. Click + symbol  per another date parameter
6. Go to properties give the name
eg: param_end_date

Find the  image

Step 2: Creating Date input Components
In the “Components” section
1. Click on Components
2. Click on Selects
3. Click on “Date input Component”
4. Go to Properties give name. eg: start_date in  my example
5. In the properties give HtmlObject. eg: start_date_select
* HtmlObject is the name of the column where you are putting
your dateinput control.
6. Give  Parameter.[It will appear once you try to type]
eg: In step 1, created parameters. So here give “param_start_date”
7. Give Listeners[click on it, you will find the list of Listeners. Click OK]
8. Repeat 3-7 for “end_date” Date input
component.

Step 3:
Find the steps in image.

 
HtmlObject is the place where you are putting your chart.

Step 4: Applying parameters for Chart & Query
            In the “DataSources”
Find the steps in the image
Find the sub sequent image for  Parameters applying for chart & Query.

do same as shown in images.

Step 5:
Save the dashboard and then Click on “Preview” button.
See the images below for sample out put with date input controls.
Preview of the dashboard with out any input controls selection

Preview of the dashboard after selecting date input controls.. find the images below one by one.

Find the image for observing whether the chart becomes dynamic or not with different date input controls.

That’s it.. You are done with date input controls on dashboard.

Jaspersoft CE v/s EE / Having Jaspersoft EE functionality in Jaspersoft CE

Jaspersoft CE versus EE / Having Jaspersoft EE functionality in Jaspersoft CE

 

Jaspersoft is world’s leading Open source BI software with more than 1.75 million download and usage. It comes in two variants, one is the community edition which is free and the other is the enterprise edition. Via this blog, we would try to understand the differences between the CE and EE. Also, we will make an attempt to understand and have Jaspersoft Enterprise Edition functionality in Jaspersoft Community Edition. Many a times, customers (esp startups and SMEs) dont have the budget or requirement to go for a full license, but they want full functionality which are present in EE, for them we have also discussed possible way outs as well.

 

a) Report Designer: Jaspersoft is known for its pixel perfect reports. This is created by iReport designer (free and open source). This tool helps in creation of complex reports with charts, graphs, tabular data, cross tabs, images etc. These reports can further be downloaded in different formats.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

b) Adhoc Report designer: Very beneficial for Business user, it gives a pivot kind of functionality, thus an end user can himself drag and drop the fields and create his own report on the fly. He can see this report as either a tabular data, or visualize it in different formats, save this and download this.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: In order to use adhoc reporting feature in Jaspersoft Community edition (CE), we can use a best of breed kind of solution. We can use Pentaho SAIKU plugin (its free), using this plugin for adhoc reporting, we can call it inside liferay and have adhoc reporting functionality in Jaspersoft as well.

 

c) Reporting Engine: Jasper reporting engine which is java based is again free and open source. It can fetch data from any kind of data source and provide picture perfect reports which can be seen, download (in different formats), printed.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

d) Dashboards: A dashboard can be a mix and match of reports, data visualizations, web APIs data, interactive parameters etc. Dashboard functionality is present only in the Jaspersoft EE

 

Availability:  Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: For implementing dashboard inside Jaspersoft Community Edition (Jaspersoft CE), we will have to go ahead with a best of breed solution. What we can do is for dashboards, we can use Pentaho CDE and CDF components. For representation of that, we can either use liferay or Alfresco.

Another alternative is we can call multiple instances of ireports inside liferay, thus creating a dashboard. For this a portlet has to be developed in liferay.

 

e) Interactive report viewing: This lets user to see the columns and perform functions like filter, arrange, sort etc.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

f) In-memory analysis: In memory basically helps in analyzing, seeing reports dashboards analysis etc on real-time and at a very high speed because it directly dumps all the information in its in-memory and doesn’t access db again and again for any requirement. This results in very high speed and throughput.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Again, to implement In-memory analytics in Jaspersoft Community edition, we will have to use a best of breed solution. We can go with the Pentaho SAIKU plugin (which is free of cost) and liferay usage for representation

 

g) Server Repository: Place to store reports, dashboards, views, mashups, analytics, user profiles etc.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

h) Report Scheduling / Report Bursting: Email scheduling of the reports (could be time or trigger based).

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

i) Support: Jaspersoft is having multiple level of supports like standard support, premium support but it is only available to enterprise edition customers.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Jaspersoft CE customer, can either will entirely depend on community support or they can come to companies like us (Helical IT Solutions), which have expertise on Jaspersoft and can help out on all the issues.

 

 

j) Mobile Business Intelligence: – Native app supporting iOS and Android platform. Touch-based browser support for iPad. iOS and Android SDK for embedding BI in native mobile app.

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

k) Metadata Layer: Metadata basically means data about data content. Via metadata layer, we create another layer containing information about the database, hence thus implementing data level security.

 

Availability:    Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: For implementing metadata layer in Jaspersoft CE, what we can do is we can use OLAP server (which is present in CE – community edition) to design metadata layer along with implementing role and user based security.

 

l) User access to reports/dashboards and other things: This facility is again present in both the versions of Jaspersoft.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

m) Data Virtualization: This basically means integrating multiple data sources into a metadata view, and then doing BI work on it. This step reduces the work this involved in ETL.

 

Availability:  Jaspersoft CE: No

Jaspersoft EE: Yes

 

 Alternatives: The entire work of data virtualization can be done by writing ETL jobs and stored procedures. For ETL, Talend or Kettle either of the tool can be used.

n) Data Integration (ETL): ETL stands for extract transform and load. Extract means extracting data from different dbs (big data, columnary databases, graphical databases etc), web APIs etc. After extracting, transform the same according to the business rules and finally load it into the target system which could be a database, data warehouse, data mart etc. Jaspersoft has ETL tool by the name of Talend (also known as Jasper ETL).

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

o) Interactive Visualizations: This basically means very interactive HTML5 charts with animations, hover information, interactivity in terms of selection, zoom in zoom out, interactive legends etc.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: These kind of interactive visualizations are not present in Jaspersoft community edition. For enabling that, what can be done is we can design plugin designed like jcharts and openflash (for openflash plugins are already available). One of the very famous example is Pentaho Community edition having interactive charts by CCC components (community chart components). We can also use CCC and thus have best of breed solution.

 

p) OLAP Server: OLAP (online analytical processing) helps in analyzing large amount of data using querying, visualizations, multi lever analysis, slice and dice, filtering etc. OLAP helps users to understand multi-dimensional data from multiple-view point. It consists of mainly three functions – consolidation, drill down, slicing & dicing.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

q) Multi-tenancy: This allows single instance support multiple customers, with each customer having his own userid password.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Multi-tenancy can be implemented in Jaspersoft Community Edition (CE) using Liferay portlet.

 

r) License: Jaspersoft CE has General public license whereas the license is having commercial license. Hence, if a client is Jaspersoft EE client, he does not need to open up his source code to the public, which is not the case with Jaspersoft CE clients.

Split Excel output of Jasper Report into multiple sheets

Hi Jasperians …!!!!

A friend posted an interesting query on LinkedIn asking how to split Excel output into multiple sheets… !!! Just worked out and sharing it with you guys..!!!

It’s a sample one.. No parameters, No headers are used…

Greetings..!!! Here are the steps to follow…!!!

Aim: To split the output into multiple sheets in Excel exporting
Solution Way: Printing data in one sheet & a bar chart in another sheet.

I have used the follwoing.
i) iReport Designer : 5.0.4 (Community)
ii) PostgreSQL : 9.2 (foodmart database)

Query I have used:
select  * from employee limit 15

Step 1: 
Open iReport desinger give it to a name and save it to your fav location.

Step 2:
Write the query in query designer area

Step 3:
Remove all the bands from report design area except
Column header, Detail & summury band.

Step 4:
Drag and drop your fav columns to detail band as shown in below figure
Drag and drop a bar chart to the summary band as shown in below figure

Step 5 :
We need to set properties at two places.

i) In the report properties
ii) In settings

i) In the report properties
Report Inspector->ReportName(report1)->Right Click->Properties
Now add the propertey.
net.sf.jasperreports.export.xls.one.page.per.sheet
and value is set to be “true” do not use double quotes for giving value but in xml code it automatically goes into double quotes.
Find the below image.

ii) In the report Settings
Tools->Options-> Click on export Settings -> In the list of export options click on Excel
It opens Excel Export Parameters
In common tab —> Check One page per sheet.
Find the image below

NOTE:
Do not forget to place page break on the place from where you want to split the page.

In this example I used page break above the chart so that data comes in one sheet and chart comes in another sheet.


That’s it… Save the report and see the preview.
I’m not seeing the preview in Server but previwing internally in the iReport.

OUTPUT
The output would be something like as follows. Find the images of excel sheet.

OUTPUT in the first sheet:


OUTPUT in the second sheet:

Dynamically hiding the columns in table component in iReport

Hi folks.. here is the next stuff I worked out today.. i.e, on dynamically hiding the columns in the table component.
Introduction:
  • For some reports we need to display data in the format of table.. To do this in iReport we use Table Component from the palette section.
  • Sometimes to take better decision  we may not want all the fields/columns to display in the tabular data display.
  • Here are the steps to design our report with hiding columns
We work out with parameters to achieve this functionality.
We need ‘n’ number of parameters as per our requirement.
This tutorial is taking the following prerequisites.
iReport 5.1.0, Jasper Server 5.0, PostgreSQL 9.2, foodmart database.
Step 1: Creating New report
File–>New–>Name your report and save in your favorite location.
Step 2:  Creating dataset.
* From the Report Inspector , right click on report name.
* Then click on Add dataset–>Give data set name and then click on finish.
                                                –> give the connection
                                                 –> write your query(first you can write a
                                                                                            simple query, then your original one)
In our example :
       Data set name  : tableDataset
       Connection       : foodmart  (It is data source)
       Query                : SELECT distinct employee_id,full_name,first_name,position_id FROM
                                                                                                                                    employee
Step 3: Creating table using Table Component from Palette.
Remove all the unwanted bands from the design area.
* We have taken only Title band and deleted the rest.
* Drag and drop table component from the palette section and fill the columns as usually.
NOTE : Upto step 3 we do the report design normally
Step 4 :  Creating parameters
We create as many parameters required.. i.e, we have to use the number of parameters equal to the number of hiding columns.
* In our example I’m displaying 4 columns(Check step 3 Query).. and I want to hide 1 column or 2 columns or 3 columns or 4 columns…( It’s our choice to hide the columns from 1st column to last column or any random columns selection.).
* Just observe the below image
and see the below image to find the properties of parameters
(I’m showing only one parameter properties in the image , for the remaining 3 parameters we have to give like this one)
There are 4 parameters in our example for four fields in the tabular component.
1st parameter details :
Name : showEmployee_Id
Parameter Class : java.lang.Boolean
Use as a prompt : check it
Default Value Expression: new Boolean(true)
 
2nd, 3rd and 4th parameters details falls in the same way as above parameter.
Step 5: Using the created parameters 
 
We have placed the table component in in Title band ( It is not mandatory.. we can keep in  summary band also )
* We use the created parameters for the columns available with the table component.
* find the image below.
We have to write printWhenExpression for the columns as shown in the image.
* i.e, for all the columns .. we have to give conditions with suitable parametername.
* In our example I have given for all the four columns in Column Header Section like below
   Column 1 : Highlight this one and go the corresponding property.
   In the properties window give the Column Print When =new Boolean($P{showEmployee_Id})
* In this way we have to write conditions for the remaining columns with suitable parameters like above.
** By default the columns in the Detail section takes the same conditions that we have written for the columns in the ColumnHeader section.
That’s it we are done with the reporting design.
NOTE: 
Our report should consists of some main query.. otherwise we can not see the output. It’ll just show our report is blank and the document is empty.
Preview:
Preview with in the iReport
* We need to give either true or false in the text box as we are taking in the parameters as Boolean.
* Give the same for all the parameters.
* In our example I have given like this for this particular preview.
showEmployee_id : false
showFull_Name : true
showLast_Name : false
showProduct_Id : true
* So we are able to see only the true valued parameterised columns in the output.
* i.e, it looks like in the below image.
* see one more output where I’ve given fist one as true and the rest are as false.
* In this way we have made our report dynamic by hiding columns  of table component.
Preview in the server:
Upload the report to the server in a regular way.
* And create the input controls for the parameters.. parameters in iReport=inputControls in
repository of inputs
* parameter name in the iReport should be same as ID of the inputcontrol
 
* Crate all the 4 input controls as shown in the images.
* Remembers the Type for the input controls is Boolean
Now go to the location of the the report in the server and see the output.
* The out will looks like in the below image with the input controls specified.
OUTPUT 1: images on the selection of input controls
 
OUTPUT 2: 
If we select ‘n’ number of parameters(input controls) we can see that many columns output in the table component.
Queries/Suggestions/Improving the concept in some other way is/are welcome @ [email protected]

Domain based report from iReport with filters

Here are the series of steps to create a domain report from jasper iReport.
In this tutorial I’m using
iReport-professional5.1.0
Jasper-server 5.0
postgreSQL(foodmart database).

Few points to note down about domains in jasper server and domainReport in iReport.

 

  •  Community Edition of Jasper Server and iReport do not provide the feature of domains and domain based reports.
  • Professional and Enterprise edition the Domains act as data sources.
  • They are a meta layer between the reports and the underlying data base.
  • The idea with Domains is they allow for easy joining of the data base tables and organize the resulting columns into a nice business friendly presentation.
  • Domains also allow for calculated fields.
  • The calculations are created using DomEL (domain expression language).
  • This is a simple language that allows for manipulation of fields that resolves to SQL in the underlying DB.

 

*  We do not create any database connection externally for developing domain based report which is a traditional way of creating database connections using JDBC and JNDI.
* Before we start developing domain based report we should create a domain in the jasper server.
* And we should connect to JasperServer from iReport.
* To know the procedure of creating domain in the jasper server plz  read the below article. http://jasper-bi-suite.blogspot.in/2013/05/creating-domain-in-jasperserver.html
* In this tutorial I have created a domain in jasperserver and named it as foodmart_domain.
* My domain consists of two tables. They are i) employee ii) store
* Fields I used for employee table are :
        first_name, last_name,gender,marital_status,hire_date,postion_title

 

* Fields I used for store table are : store_number,store_city,store_country
Do this first
Go to window->Click on Domains –> we can observe the window appearing just below to the Report Inspector window which is known as Domain Window.
Step 1: 
File->New->Click on Domain Report(appears at left side)->Click on BlankA4->Click on Finish.
Step 2:
We will navigate to the following window.
* Give all the details
  Connection : This is nothing but connection from iReport to JasperServer
                          ( We connect from Repository panel of iReport)
  Domain       : Select a domain which you have already created in jasper server.
                          ( In this tutorial I have already created a domain and named it as   foodmart_domain, and I’ve not shown the procedure of creating domain in this tutorial b’z we are    learning how to create a report using domain but not domain creation )
 Filters          :  Filters are nothing but input controls in the domain based report.
                          * We can select the field which we want to use as input control
                          * In this tutorial I have used two filters(input controls).
Find the images below for filters creation.
 
Available fields :  As we successfully connected to our foodmart_domain we can observe that the tables(of course fields also.. just double click on the folder of employee or store.. we can observe the fildes also ) available with the domain left side of the above image.
* Condition Editor : To use the filters concept we just have to
       –> highlight(click on the field) the field from Available fields panel
       –> then click on create condition
       –> Field name : When you highlight the field from available fields panel it will automatically appear here.
      –> Comparison :  give the condition from the drop down list.
       –> Value(s)      :   give some value ( Like we give in the parameter default expression in general reports)
       –> Check the is prompt ( This is used for popping up the filters)
    * In this way we can add as many filters(input controls=parameters) to the report before we design the report itself.
    * We can add the filters in the middle of the designing of the report also.
    * We can also change, delete, add/update the filters and corresponding conditions.
In our example I have given two filters. They are : i) gender ii) store_country
1st filter :
Field Name : gender
Comparison : Equals
Value(s) : M

 

2nd  filter :
Field Name : store_country
Comparison : Equals
Value(s) : USA
* Click on next
* Give the name for the report and location to save the report.
Step 3 :
When you click on finish you are ready to design your report….
* You can observe the tables and fields available within the domain in Domains Window
* From there you can drag and drop the fields to the details band of the design area.
* The complete design of the report you can find in the below image.
That’s it we are done with report … A domain report..
NOTE: 
When we designing domain report , the iReport engine generates domain query language on it’s own( defaultly)
* This you can observe at Report Query Area.
* Find the image below for our example
* We have not provided any SQL query to generate the report.
* We have not added any parameters in the Report Inspector of Parameters section.
* But the iReport engine has provided the domain query and parameters from jasperserver.
* When we work with domain based Reports from iReport these all things done by iReport Engine.
How to see the preview of the report in Report Designer ?
We can directly preview the output in the designer by clicking on preview tab
(OR)
You need to export this report to jasperserver and have to see the preview as follows.
* Right click on the Folder-> click on Run JasperServer Report
* You can see the output(preview) in new a new window(Report Viewer Window)
How to see the preview of the report in the JasperServer ?
upload the report to the server and see the preview.
The filter which we gave at the time of report design become input controls in the server and looks like in the following image.
Now click on Ok and see the preview.
We are done with simple domain based report from iReport.
