Exception in printing Report with jboss-4.0.1 sp3

java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

 

I ve been building reports with JasperReports for quite Some time now and the Last report I built I guess has exceptionally bench marked JasperReports with use of about 80+ SubReports with multi layered approach of dataSorces Implementaion.

But for all this time I was using JasperReports on jboss-4.0.1sp1.

Recently when I moved my application on to jboss-4.0.1sp3 I got the exception listed above.

 

java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

 

I was able to resovle the issue by dropping jasperreports1.2.2.jar to default/lib directory of JBoss.

I would be glad if somebody could enlighten me on this issue. I guess its due to the classloading performed by jboss-4.0.1sp3.
