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

[Tom Jordahl <to...@macromedia.com>]

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.

Subject: WSDL2Java throws a Null Pointer exception when processing multipa rt WSDL

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
	ava.lang.NullPointerException

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
