Subject Code generation fails when using the WSDL..

Hi,

I am trying to generate client side code for the following WSDL.

And I got the following error.

It seems that targetNamespace attribute is mandatory in schema definition. I
could use Axis 1 to generate the code for this WSDL. There I dont face the
problem with this mandatory namespace attribute.

Could some one help me with modifying the WSDL to use for Axis 2.

Thanks,
Paul
