Report With Aggregation Fields Could Not Be Shown After Upgrading Application Server

mmah

After I upgraded the web application server to Weblogic 10.3 from 10.0, Most of the reports that I've designed earlier on could not be generated. This is unusual as when I run in 10.0, it is able to generate the reports properly.

Interestingly, on a thorough testing, I noticed that reports that do not have aggregation fields (e.g, those with count, total, average) could be generated, but those that do have could not. As a result I got a preparedQuery exception (see part of the stacktrace below).

Can someone please advise on this one? I've tried asking a few times but without success. I suspect that maybe the BIRT runtime engine might not work properly. My BIRT runtime engine is 2.3.1, as well as the version of the report designer.

Hi,<br />
<br />
take a look at my post here : <a class='bbc_url' href='http://www.birt-exchange.com/forum/deploying-integrating-birt-report-engine-applications/14706-birt-3-2-3-weblogic-9-2-java-lang-assertionerror.html#post46568'>http://www.birt-exchange.com/forum/deploying-integrating-birt-report-engine-applications/14706-birt-3-2-3-weblogic-9-2-java-lang-assertionerror.html#post46568</a><br />

No more AssertionError for me with version 2.5M6.
