problemes with subreport : multi-thread...

2006-06-23 06:57

My problems is that i have a report with 4 level of subreport in like:

A,B,C,D are javaObject

A has many B which have many C which have many D

When i have build my jasperReportObject and when i try to compile the jasperReport. He work without stop.

When i debug, i just have information that he stop... or loop in the method: fillReport()

Is there everybody whose have work on succession of subreport yet.

I'm not sure but i think i have some problems with multi-thread

A contains some subreports, one is B.

B contains C, and C contains D.

This is working...although it´s tedious.

 

Hope this helps.
