I wrote a .asmx web service which I'm trying to consume from a java client. I'm using axis2's wsdl2java to generate code. But it says that the wsdl is invalid. What exactly is the problem here? It is .net which generated the wsdl automatically after all. Are there problems with wsdl standards, rather the lack of them? What can I do now?

I'm putting the wsdl here for reference.
