Cause:
======
The project has both xsd and wsdl in the project. The wsdl included the full definition of the xsd.

The conflict is that the same element under same namespace has duplicate definitions in different files(locations). This leads to the runtime exception.
  
Resolution:
=========
Remove the duplicated definitions of one element. You can do one of the following:

- Remove the seperated xsd file as it has completed contained in the WSDL.
- When generating the WSDL, reference to the existing xsd instead of including it.

After the modification, rebuild the ear.
