Hi,
I'm presenting a question belonging to both the tomcat and xerces mailing lists, but
so far no luck on the xerces list.
I'm using the Xerces toolkit to build my own XML-parser. Running this parser
standalone works fine. My second step is to move my parser into tomcat to run as a
servlet.
This is where my problems start. I get an error:
java.lang.NoSuchMethodError

...
This method exists in the DOMParser class found in the xerces.jar archive. Why the
tomcat environment can't find it, I don't know.
For anyone interested:
I'm attaching my files test_parser.java and myParser.java, and a XML file and XML
schema to test with. You need to edit files to set the correct IP-address to use.
For xerces users: This occurs when I set all three options validation, schmasupport
and namespaces to true. Any other combination do not give this error.
Any suggestions?
