Description

Assuming you have split out XSDs into their own project, and you have an endpoint configured like so:

        <jaxws:properties>
            <entry key="schema-validation-enabled"
                   value="true"/>
        </jaxws:properties>

What happens is, if you send a request to your endpoint it can't find the referenced XSDs.

The error message I get differs on whether I use 2.2.6 or 2.2.7-SNAPSHOT. I'm not sure if they both represent the same problem. In 2.2.6, the problem states that the WSDL had a "premature end of file", but when I debugged I found it was simply the fact the schemas it references could not be found:

2.2.6 error

In 2.2.7-SNAPSHOT it actually lists the schemas it could not resolve, and gives another message stating "this schema contains two occurrences of 'urn:hl7-org:v3,FICR_IN100204CA'.":

I've tried several things, including catalog files, but I can't resolve this. It seems to be the underlying schema parsers themselves that have the issue. Spent a few days trying to debug far enough into the issue to formulate that opinion, so unfortunately I have no patch to contribute.

To replicate:
1. Unzip the attached project
2. Change directory to CXFSchemaRefProblemPom
3. edit pom.xml to switch to the appropriate version of cxf and cxf-codegen (2.2.6 or 2.2.7-SNAPSHOT (which is the one the project is currently set for))
4. switch to CXFSchemaRefProblemWar and execute mvn jetty:run
5. switch to the parent directory where sample-req.xml exists and send a request to the endpoint: curl -d @sample-req.xml -H "Content-Type: text/xml;charset=UTF-8" http://localhost:8080/ProcessClaim
