<p>
I recently migrated a CR4E 1.x project to the latest 2.0 update 3. After a few tweaking of my code, I was able to get the everything working except "Export" or "Print". Whenever I clicked the icon, I am getting an "Error" page returned by "CrystalReportViewerHandler".
</P>
<p>
After enabling "crystal_exception_log_file" parameter value in web.xml, I was able to find out below stack trace. The application is running in WebSphere 6.1 container. Can someone shed some light on what possible cause it might be?
</p>
Thanks,<br/>
