Java – Error parsing WSDL message

I have the following wsdl : http://pastie.org/804441 . I get the following errors with the wsdl. Im using it in a tool called XAware, which is a data integration tool.

This question is not about XAware. Just looking at the errors below and the wsdl file,does it indicate some problem with the WSDL im using or is my WSDL fine ?

Please help.
Thank You.
