Subject [jira] Created: (CXF-3061) Resolving a DTD from Schema fails when Endpoint definition uses wsdlLocation

Resolving a DTD from Schema fails when Endpoint definition uses wsdlLocation
----------------------------------------------------------------------------

                 Key: CXF-3061
                 URL: https://issues.apache.org/jira/browse/CXF-3061
             Project: CXF
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.2.11, 2.3.0
         Environment: Windows, Java build 1.6.0_21-b07
            Reporter: Marco Zapletal
            Priority: Minor


This bug affects endpoints, which have schema validation enabled and also contain a wsdlLocation.
If a schema of the WSDL holds a reference to a DTD, the resolution of the DTD fails. These
results in the fact that schema validation is repealed. This issue has already been raised
on the mailing list (cf. http://cxf.547215.n5.nabble.com/SAXException-resolving-resource-http-www-w3-org-2001-XMLSchema-dtd-td551217.html
and http://cxf.547215.n5.nabble.com/SAXException-resolving-resource-http-www-w3-org-2001-XMLSchema-dtd-td3200050.html
, respectively).

The resulting stacktrace is:

I attach a test case to this issue. Please note that the test case passes, since it is not
possible to check this error with any asserts on the client side. However, you will see the
stacktrace raised by the service.
