WSDLToJava Error: Thrown by JAXB: 'CodeGroup' is already defined ...
OTA_CommonTypes.xsd
----------------------------------------------------------------------------------------
Key: CXF-4163
URL: https://issues.apache.org/jira/browse/CXF-4163
Project: CXF
Issue Type: Bug
Components: Tooling
Affects Versions: 2.5.2, 2.4.2
Environment: Windows XP
Java SDK 1.6.0_26
Eclipse IDE 3.5.2
Reporter: Yoann Guerro
My WSDL imports several schemas. Some schemas import/include other schemas.
Some schemas are imported/included by several schemas.
Running WSDL2java with an ant task with the following options I got several
errors such as:
[java] WSDLToJava Error: Thrown by JAXB:
[java] Thrown by JAXB:
[java] 'CodeGroup' is already defined
[java] at line 175 column 2 of schema
file:.../OTA/2010B/OTA_CommonTypes.xsd
[java] (related to above error) the first definition appears here
[java] at line 45 column 2 of schema file:/.../My_CommonTypes.xsd
OTA_CommonTypes.xsd defines the following type:
<xs:attributeGroup name="CodeGroup">
...
</xs:attributeGroup>
My_CommonTypes.xsd defines the following type:
<xs:attributeGroup name="CodeGroup">
...
</xs:attributeGroup>
OTA_CommonTypes.xsd is included by a schema defining a target namespace
"http://www.opentravel.org/OTA/2003/05/OTA2010B";
My_CommonTypes.xsd is included by a schema defining a target namespace
"http://xml.example.com/MyTypes";
XML schemas as well as WSDL are valid (other frameworks generates code without
any issue - and even CXF WSDL validator returns a success) and the types should
be generated in distinct packages, therefore without any conflicts.
My assumption is that CXF wsdl2java fails at resolving the type namespace with
schemas which are chameleon schemas (no targetNamespace attributes) which is
the case for all OTA type schemas.
A work-around that I would like to avoid as I'm exposing the WSDL to different
clients using different frameworks and I don't want to create 1 WSDL per
framework, would be to add targetNamespace attributes to all chameleon schemas.
