Re: Re: JasperException caused by schema validation via JSP /Servlet

[Mi...@student.unisg.ch]

Eric,
I agree with you, the exception seems not to be emitted by Xerces (I copied the
full trace below), but does this mean that in this case there is a problem with
Tomcat/JSWDK? I hope the error is not in my JSP but I tried to check that by
validating non-Schema XML docs and that works fine. If SAXParseExceptions occur
these are also caught correctly.
Would it help if I send you the files?
Thanks for your help,
Michael

If the stack trace you gave is the complete stack trace, then the exception
presented is definitely not emitted from Xerces-J Parser. Certainly the
jasper package can mask the Exception thrown from the Xerces-J parser,  in
that case, we need more information on this.
