Tanks I will try that download. BTW, Yes I am trying to run both overall report and process summary report.
I have been able to run these 2 reports with following cases:
1) deploy Birt.war on WAS 7. Able to generate reports thru this - OK (addeded jdbc jar in classpath of viewer)
2) open these reports in Eclipse - Designer - able to see data ok- (added jdbc jar in classpath)
3) Installed Report Engine API in D:/xxxx - added jar in ReportEngine/lib - works OK
Error Case:
Deployed Console on WAS 7 - Birt Service is pointing to Report Engine installed in D:/xxxxx. Service initalized OK, Both Report Templates show up in Console - Reporting Section along with the Error mentioned in the original post.
(In this cases copied all jars from ReportEngine/lib to Console-server-war/WEB-INF/lib along with jdbc Jar, so they are in class path of Console).
I dont see any other errors in WAS server and ffdc logs. BTW, I also configured the jndi datasource in report template.
