I am designing a report using Birt and Eclipse. When I deployed inside the Tomcat I am getting this problem.

I configured web.xml and context.xml files and copied the ojdbc14.jar file into webapps\birt\WEB-INF\platform\plugins\org.eclipse.birt.report.data.oda.jdbc_2.6.2.r262_v20110127\drivers folder.
After running the report though browser I am getting this problem. Initially it is showing progress bar. But after some time (30min) it is showing blank report.
My query may take one hour to execute. But report showing blank with in 30min. What is the problem?
This sounds like it could be related to some kind of session timeout. I believe that Tomcat has a default session-timeout set to 30 minutes. I believe this setting is within the web.xml file.
