Hi,

I just want to ask if any of you has encountered the following exceptions, and what are the possible reasons for these exceptions, when trying to run reports through the web viewer.


Kindly check out the attached images.

Thanks.

P.S.

Sometimes, I also get this error message:
1.)
HTTP Status 500 -

type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

2.)
java.lang.ClassCastException: org.eclipse.birt.core.template.Parser$LookaheadSuccess cannot be cast to java.lang.Exception
