Hi,

I try to create a new Jazz repport with BIRT. Therefor I use the tutorial https://jazz.net/wiki/bin/view/Main/ReportsCreatingANewReport

But at Step 7 in "Creating the report", I got the following exception: 
org.eclipse.birt.data.engine.core.DataException: Data engine operation failed due to an unexpected exception. 

The expression cannot be null or empty.


Can anyone tell me why this happened? The creation of the Data Source was without any problems. The test of the connections was ok.

I use Standard RTC with an DB2 Database and a Websphere Server.

Thanks and regards

Are you using RTC 1.0.1 for both server and client?

The problem was, that I have user BIRT 2.3, instead of BIRT 2.2. With BIRT 2.2 this error doesnt occure.......
