Created attachment 241909 [details] birt exceptions file I develop a report with bar chart by birt, and I use birt WebViewerExample as web server.there are some issues when I access my developed report.The way I access is as follow: <html> <frameset cols="20%,20%,20%,20%,20%"> <frame src="http://localhost:8080/birt_viewer/frameset?__report=sdprov.rptdesign" /> <frame src="http://localhost:8080/birt_viewer/frameset?__report=sdprov.rptdesign" /> <frame src="http://localhost:8080/birt_viewer/frameset?__report=sdprov.rptdesign" /> <frame src="http://localhost:8080/birt_viewer/frameset?__report=sdprov.rptdesign" /> <frame src="http://localhost:8080/birt_viewer/frameset?__report=sdprov.rptdesign" /> </frameset> </html> I try to simulate concurrently accessing my report,but the exception is thrown the message that says "The viewing session is not available or has expired ".Now I know that Birt engine parse .rptdesign file and will generate a file named with .rptdocument and render the birt chart to svg image . Their parent directory associate with session id and the time when the URL request arrive the web server. I try to use Batch script to open IE.Its content is for %%a in (1,2,3,4,5,6,7) do ( start "C:\Program Files\Internet Explorer" IEXPLORE.EXE http://localhost:8080/birt_viewer/frameset?__report=sdprov.rptdesign ) I can get different sessionID to access my report ,but there are still some issues. org.eclipse.birt.report.engine.api.EngineException: Error happened while running the report.

one help me ? Thank you for replying
It seems to be related to https://bugs.eclipse.org/bugs/show_bug.cgi?id=429393 You should try to replace a class of the runtime as suggested in this topic, and confirm if it solves the problem: http://www.eclipse.org/forums/index.php/t/644300/
