Hello gentelmen. I have an issue to set up my datasource via 'JavaBean set datasource ' option and, as well, same result coming out when I am trying to use other option 'Custom JRDataSource'. I created jar file with MyDataSource class, which returns Map from getBeanCollection() methods. And when I test the connection environment to this class I do not receive "Connection test successfully", I receive "General problem com.myproject.web.report.MyDataSource.createBeanCollection()". I don't understand why. If somebody can help me to understand the reason? (version jdk and jre 1.5, version compiler from Eclipe 1.5). Thank you Post Edited by borisnikfai at 03/14/2012 15:30 Post Edited by borisnikfai at 03/14/2012 15:43
