Description

Hi the following content is taken off a mail on the Axis2 user list where a user encounted this problem. According to lawrence this may be due to a change in the woden validation framework.

The original mail by Daniel is in the quote section.

We found a problem using a wsdl2java tool with WSDL v.2 files.

Last month we were able to generate stub/client Java code without problems.

<wsdl:description
   xmlns:wsdl="http://www.w3.org/ns/wsdl"
   targetNamespace="urn:wsdlSamples"
   xmlns:tns="urn:wsdlSamples"
   xmlns:dtns="urn:wsdlSamplesData"
   xmlns:wsoap= "http://www.w3.org/ns/wsdl/soap">
....

But with the latest revision from SVN (#635534) we received the following
error:

Exception in thread "main"
org.apache.axis2.wsdl.codegen.CodeGenerationException: Error parsing WSDL

After the following modification the generating of stub/client passed.

<wsdl:description
   xmlns:wsdl="http://www.w3.org/ns/wsdl"
   targetNamespace="http://127.0.0.1/wsdlSamples/all.wsdl"
   xmlns:tns="http://127.0.0.1/wsdlSamples/all.wsdl"
   xmlns:dtns="urn:wsdlSamplesData"
   xmlns:wsoap= "http://www.w3.org/ns/wsdl/soap">
...

Is it a problem of Description1001.validate() method ?

I've reproduced this failure. The problem is the Description1001 assertion attempts to open a stream to the target namespace to test if it is dereferencable. A stream cannot be opened for the urn scheme and a NPE is thrown.

Fixed. I've added a list of schemes for which the assertion can test. The list currently contains http, ftp, and file.
