[jboss-user] [JBossWS] - Exception in wstools wsdl-java, unwrap=true

[klease]

I'm trying to generate a client for a .net webservice. The wsdl uses the wrapped style with anonymous elmeents for the methods and responses, like this:

 <s:element name="TwoParamFunction">
  |       <s:complexType>
  |           <s:sequence>
  |             <s:element minOccurs="0" maxOccurs="1" name="arg1" type="s:string" />
  |             <s:element minOccurs="0" maxOccurs="1" name="arg2" type="s:string" />
  |           </s:sequence>
  |       </s:complexType>
  |       </s:element>

I run the wstools from the 1.0.3 release, with following parameters.
 
  |  <wsdl-java unwrap="true" file="UnwrapBug.wsdl">
  |     <mapping file="jaxrpc-mapping.xml" />
  |   </wsdl-java>
  |  
Environment is linux, jboss 4.0.4.GA, jbossws-1.0.3, jdk 1.5.0_07

I get the following error:

------------------
I assume this is a bug?
The workaround is to modify the wsdl so that the elements reference separate defined type elements, like this:
 
  | <s:element name="TwoParamFunction" type="tns:TwoParamFunctionType"/>
  |       <s:complexType name="TwoParamFunctionType">
  |           <s:sequence>
  |             <s:element minOccurs="0" maxOccurs="1" name="arg1" type="s:string" />
  |             <s:element minOccurs="0" maxOccurs="1" name="arg2" type="s:string" />
  |           </s:sequence>
  |       </s:complexType>
  | 
Then correct java is generated.
