Hello Mullin,

the stacktrace you posted is not enough to track your problem properly, so please give a little more details by answering the following questions:


  • Did you generate an application using X-Application generator?
  • Please attach the schema your application is based on
  • Please tell a little more of how it came to this error (which steps did you perform before?)

Before answering the questions above you can try one thing:
Delete the contents of the Tomcat work directory and restart Tomcat. If this doesn’t help, more info is needed.

Thank you for your contribution

Has this problem been solved?

If not, could you please post a recent stacktrace
together with the file Error_1.java from your
work directory? This should help to track down the
problem.
