Cannot call Java Web Service in Visual Studio 2003

I can call this Java Web Service in JDeveloper without any problem.
The parameter is using string array.

I can add the WSDL url as a web reference into Visual Studio 2003. It
found the service description and the method. However, the web
reference name wasn't shown up in the Object Browser. No matter what I
tried to call it in aspx, I always got "Compiler Error Message:
BC30002: Type 'CIRS_Mapper.WebReference.SpeciesWebService' is not
defined.".

I tried a microsoft web service and can see it in the Object Browser
and can call it without any problem.

Anybody knows the reason?
