I have create in Report variable with type of 'myJavaClass' (eg: 'Value Class Name' -> de.testlib.jasper.myJavaClass). The JavaClass with the name 'myJavaClass.java' I created before: This JavaClass has getter and setter for Java variables. I need myJavaClass.java for manipulate the values I get from Jasper. In next step I want to use this JavaClass as variable in Jasper as variable. But I have a big problem how to define expresions (Initial Value Expression, Increment type, Incrementer Factory Class Name). A) Initial Value Expression: 'new myJavaClass()' B) Expression: '$V{myJavaClass}.add(3)' In the groupefooter I have a field to get the value of '$V{myJavaClass}' with '$V{myJavaClass}.getData()' When I start the Report I get the Exception with message, that it is not possible to set value in the JavaClass. Why isn't possible to set value to myJavaClass with Jasper? I thing it should be possible, but how? I'm looking for any ideas... -itworker-
