I'm getting a RuntimeException while executing some code that depends on generated xmlbeans classes. I can't figure out if this is:

• me missing something during code-generation or packaging
• a runtime dependency missing
• a misleading error message, and I should be looking elsewhere.

The xbean.jar version is the same in the build and execution environment. Anyone seen this before or have any ideas?

Thanks.
