ClassCastException on WebLogic BEA Servers

eliac

Dear All,

I have came recently across this very strange error. Whenever a report that contains cross tabs (Data Cubes) is being rendered in excel. On BEA servers only i get this exception. I tried on Tomcat and on WebSphere as well, the report did render normally without any exception.

I am using actuate excel emitters to render the reports in Excel and BIRT 3.7.1

Any help is much appreciated. Below are the error logs.

Thanks in advance

Regards
