Dear readers, this blog talks about Date Calculation using Joda Time Library In iReport

By using Joda Time Library , we can give default value expression for any datetype parameter .

Steps for using joda time library in iReport  :

1. Download joda time library ,

2. Put its jar file “joda-time.jar” in the path of iReport : Tools/Options/Classpath/.

3. In the main report section properties , set import property to “org.joda.time.DateTime”

Without  double quotes.

4. Now with the above configuration , we will be able to do any type of date calculation

5. Example :

   a. Start Day Of Current Month :

Take two parameters : now and startday respectively

For ‘now’ parameter give its class name as ‘java.util.Date’ and default value expression as new DateTime.now().dayOfMonth().withMinimumValue().withTimeAtStartOfDay()

b. Last day of previous Month :

Take two parameters : now and endday respectively

For ‘now’ parameter give its class name as ‘java.util.Date’ and default value expression as new DateTime.now().minusMonths(1).dayOfMonth().withMaximumValue()

In the similar way we can do any type of date calculation for default value expression.
