Java EE (Java Enterprise Edition) General Discussion

All,

We were previously using adb with Axis2 and all was working fine. Recently we have been prototyping jaxb with Axis2. We have a complex wsdl which imports several schemas and in turn the schema has additional schema imports. In this scenario...errors are thrown. When we researched into it...we figured out the code generation tool of Axis (JAxB) is not able to handle a chain of schema imports based on the scenario described above. I get the following error:

Exception in thread "main" org.apache.axis2.wsdl.codegen.CodeGenerationException: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

ANy help is appreciated. The exact wsdl works for ADB class generation. Also...I do have the activation-1.1.jar in my classpath.

Thanks
