Hi there,

I just updated my Weblogic 8 application with Xerces 2.5 (need to have XML Schema support) and Tamino API for Java broke with the Exception:

Any clues?

Thanks in advance,

Sorry, we havn’t yet tested throughly with Xerces 2.5. Anybody out there has any clues about the difference between Xerces 2.5 and Xerces 2.3?

Interesting would also be if this only happens in a EJB server environment or also in a plain Java context.

Well, I rolled back to weblogic 7.0 SP3, now using xerces 2.2 and I am having the same error. This happens only during update operations on an XML document. Very strange. Exception below:

Hi Juan,

after analysing the stacktrace, we believe that this might be a bug in the Tamino API for Java. If you have a maintenance contract, could you please communicate this problem to your Software AG Support contact, so that it gets tracked properly.

Thanks.
