First issue I see is that you are creating your own version of afterGroupInit at the begining of you file. You code should be down further in the existing afterGroupInit.

 

In Report Properties have you set Scriptlet Class to "Use iReport internal scriptlet class"?

thanks for your reply Mr.svenn, if i use internal scriplet then how can i call that return value?.. did any java file created while we use internal scriplet?

if yes. then where the java file resist?
