Subject [jira] Updated: (AXIS2-1885) WSDL2Java with XMLBeans binding codegen fails with "Duplicate global type" when schema is imported from WSDL file and another schema file.
Date Mon, 18 Dec 2006 21:47:21 GMT
     [ ]

Michael Krumpus updated AXIS2-1885:


This example shows clearly that WSDL2Java fails with XMLBeans binding when message.xsd is
imported from the WSDL and from another schema.

Drop the axis2 libraries into 'lib'.

Run 'ant codegen' to demonstrate failure.

Run 'ant codegen-xmlbeans' to demonstrate success using the standalone XMLBeans code generator.

> The problem here seems to be that when message.xsd is imported in the WSDL file *and*
imported in another schema that is also imported in the WSDL file, the code generation process
does not realize that they are the same schema, thus leading it to believe that the type MessageContext_Type
is a duplicate global type when it is not.  I will attach an example that demonstrates the
problem clearly.

 When running scomp as a standalone utility, fully qualified absolute paths are passed into
this method, but when using WSDL2Java, relative paths are passed in.
