Unfortunately, the stack trace for the *real* exception is printed to standard error on the server in version 2.2. I'm not sure whether this ends up on the console or in a file in %TOMCAT_HOME%\logs. You will probably need to get this trace to be able to track down the problem. Or, if you can, switch to SOAP 2.3.1 or the current build. These return better exception information to the client.
Also, what versions of Tomcat and Xerces (or other XML parser) are you using?
