RuntimeException from xmlbeans - can't find compiled schema

java xml xmlbeans

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.

The answer of John was a good hint for me. I generated Java classes with xmlBeans and copied the source files out of the "noNamespace" manually in my project to modify them. unfortunately I did not recognize that there were also generated class files in the "schemaorg_apache_xmlbeans" folder and did not copy them.
After switching to the usage of the generated jar-file everything worked fine for me.
