Subject [jira] Commented: (AXIS-2058) WSDL2java fails with an error code "Type ... is referenced but not defined" when run against valid schema.

Robin Taylor commented on AXIS-2058:
------------------------------------

Having just created this I have realised it appears to be exactly the same problem as another
currently open problem - Axis-2022.

Apologies for the duplication.

> 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 ...

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.
