wsdl4j compatibility

[Ben Wyckoff]

Hello,
I am a relatively new Axis user, and I have been trying to both create and consume web services. I found an interesting article at <http://www-106.ibm.com/developerworks/webservices/library/ws-udax.html?dwzone=webservices> on Dynamic Discovery and Invocation of Web Services which uses uddi4j, wsdl4j, and Axis to discover a service, parse the WSDL, and then invoke using Axis.

I'm not interested in the uddi4j now, but am very interested in the wsdl parsing and Axis invocation steps. Using wsdl4j to extract the relevant data from a wsdl file automatically would be a big help for me.

Unfortunately, the only file the wsdl4j WSDLReader seems to parse ok is the WebMath_Impl.wsdl file that is part of the sample code for the article. I tried the WSDL from Axis 1.0 and 1.1RC1 .jws?wsdl services, and also from a few services offered through xmethods.com. In all the failure cases, I get the following error:

WSDLException: faultCode=OTHER_ERROR: No WSDL interface definition found.

And yet, these services do work, and both Axis and SOAP::Lite clients can process the WSDL and make successful queries.

Can anybody offer any insight or alternatives?

thanks,
Ben
