RE: WSDL2Java throws a Null Pointer exception when processing mul tipa rt WSDL

[Mike Burati <mb...@bowstreet.com>]

You might also try getting a more recent wsdl4j.jar

We had some problems with our own use of WSDL4j parsing multi-part
(imported) WSDLs a while back that were fixed in part by moving up to a more
recent WSDL4j (looks like ours was built in 8/02 from the class files I see
in the jar file) among other things...

The classes in the wsdl4j.jar that come with AXIS1.1beta appear to have been
build in 6/02

This sounds like a bug to me, but it looks like it might be the WSDL4J code
and not the Axis code.  You might want to try just using WSDL4J to see if it
can read the multi-part WSDL without throwing a null pointer exception.

Hello, 
I have WebSphere service which is based on  Apache SOAP 2.x that has
multipart WSDL.
When I try to create a client with this, WSDL2Java throws a Null Pointer
Exception.

I have tried this with both release 1.0 and 1.1b.

	java org.apache.axis.wsdl.WSDL2Java
http://localhost:8080/simple/wsdl/smallTest-service.wsdl

It's easy enough to work around, I just merge the files into one,  but I
wanted to clarify if Axis is meant to support this? 

Here is the WSDL for a simple case.
service
