WSDL2java fails with an error code "Type ... is referenced but not defined"
when run against valid schema.
----------------------------------------------------------------------------------------------------------
Key: AXIS-2058
URL: http://issues.apache.org/jira/browse/AXIS-2058
Project: Apache Axis
Type: Bug
Components: WSDL processing
Versions: current (nightly)
Environment: Windows XP, JDK 1.5, Axis 1.2 (newly downloaded)
Reporter: Robin Taylor
Can anyone help ? I'm trying to run wsdl2java against some wsdl published by
the IMS Global Learning Consortium but without success. I'm 90% sure there is a
bug somewhere but there is a possibility that my XML knowledge is letting me
down. I have attached a cutdown version of the original very complex wsdl. It
may look a bit pointless but that is because I have left in just enough code
for it to be valid and still produce the error. The problem lies in an imported
piece of XML schema in the third file ...
<element name = "createResourceListRequest">
<complexType>
<sequence>
<element name = "test1" type = "xsd:string"
maxOccurs = "unbounded"/>
</sequence>
</complexType>
</element>
<element name = "test2" type = "xsd:string"/>
<element name = "createResourceListResponse">
<complexType>
<sequence>
<element ref = "tns:test2" maxOccurs =
"unbounded"/>
</sequence>
</complexType>
</element>
The two elements "createResourceListRequest" and "createResourceListResponse"
should be essentially the same but are coded differently to illustrate the
problem. wsdl2java prodoces the following error relating to test2...
C:\Documents and Settings\RTAYLOR3\My Documents>java

at java.lang.Thread.run(Thread.java:595)
Strangely, if I remove the maxOccurs attribute from the ref to tns:test2 then
the command runs successfully. This is what makes me pretty sure this is a bug
rather than duff code. I have attached below the entire wsdl/xml which
comprises 3 files. I am running a recently downloaded version of Axis 1.2 with
J2SE 5.0.
Any help would be greatly appreciated.
Thanks, Robin Taylor.
