since your posting some time has passed, but it might be interesing to others that we made the schema validation in combination with the wsdlLocation attribute of @javax.jws.WebService running for
* JBoss 4.2.3 and
A wsdlLocation like wsdlLocation="WEB-INF/BasisartikelKonfigurierenInternService.wsdl" and did the job for us.
(The error message occured when the attribute schemaLocation of the annotation SchemaValidation was used with the wsdl as a value of the schemaLocation.)
It is possible to start with a WSDL that is generated by JBoss under
and then copy it to the WEB-INF folder.
And there some modifications can be done on the WSDL, for instance if someone wants an xs:choice element or some special simple types in it.
With best regards,
