Urgent! Strange problem when calling jasper report from STRUTS
Hi,

I have a problem when calling a jasper report from Struts and I have no idea what I am doing wrong.

I get a "java.lang.IllegalStateException: Cannot forward after response has been committed" exception!

My code is below...
Action:
// I pass a list with one map to this "prepareReportJrxml" method

AbstractBaseReportBean:


exportReportPlainXls method:


at this point I get the error:
AbstractBaseReportBean:


I dont know how to eliminate this error.
I think, this is also the reason why no data will be passed to the excel sheet (I think).

Thanks a lot ! cheers

Actions that write their own response should return "null" (not an ActionForward) so the framework doesn't attempt to continue processing the request.
