Hi, I'm developing an web application (using Java) on the Google App Engine...
The thing is the my logs are full of this weird stderr message <stderr>: SystemId Unknown; Line #57; Column #31; Failed calling setMethod method I did googled a lot and asked this question on many places, but no one knew the reason why and recently I bumped into several posts with similar stderr that was caused by Xalan , the stderr were of the same structure : <stderr>: SystemId Unknown; Line #XXX ; Column #YYY; Failed calling setMethod method So I was wondering... any chance that the stderr message that I'm getting is cause by Xalan? I'm not making explicit use of Xalan, by I have added the following files o the lib folder (in order to run JSF2 application on GAE) - serializer.jar - xalan.jar - xercesImpl.jar - xml-apis.jar - xsltc.jar Help will be much appreciated... Regards, Daniel.
