I have an issue with schema validation that I believe is related to
bug https://issues.apache.org/jira/browse/CXF-3233
Here's the full story, log files, and a workaround.
I have a jaxws:endpoint configured to use a wsdlLocation in a Jar file
(real namespaces etc removed):
<jaxws:endpoint xmlns:my="urn://my.namespace"
address="jms://"
transportId="http://cxf.apache.org/transports/jms";
serviceName="my:service" endpointName="my:port"
implementor="#myImplementor"
wsdlLocation="jar:file:WEB-INF/lib/my.jar!/path/to/my.wsdl"> ...
With turn schema validation off, everything is fine.
When I enable schema validation (<entry
key="schema-validation-enabled" value="true" />) incoming requests are
validated and accepted / rejected as expected.
When a valid request comes in and passes validation, I can see it's
getting into the code, and the code is returning successfully.
However, after the code returns, nothing comes back from CXF. It's a
complete blank.
As per Dan's suggestion on IRC, I turned on logging at the root-trace
level and added a custom OutInterceptor to see what was happening.
I created an interceptor that loops through the available interceptors
and prints them out:
public void handleMessage(SoapMessage message) throws Fault {
log.debug("--- HELLO OUT INTERCEPTOR handleMessage ! ---");
for( Interceptor<? extends Message> interceptor :
message.getInterceptorChain() )
debug.log("FOUND INTERCEPTOR:" + interceptor.getClass().getName());
}
}

Payload to be sent out is :[]
send out the message!
server sending reply:
===== End log for interceptorswith schema-validation=true =====
You can see that the payload is empty which explains the blank
response I get when I turn validation on.
It's like the payload got lost somewhere along the way with the
exception being thrown.
I imagine what's happening is that on the outbound validation, it
can't find any XSD's to validate against.
I tried to remedy this by explicitly telling it where to find the
schemas that are in the jar (which would be duplicate code):
<jaxws:endpoint [...]
wsdlLocation="jar:file:WEB-INF/lib/my.jar!/path/to/my.wsdl"> ...
<jaxws:schemaLocations>
<jaxws:schemaLocation>jar:file:WEB-INF/lib/my.jar!/path/to/1.xsd</jaxws:schemaLocation>
<jaxws:schemaLocation>jar:file:WEB-INF/lib/my.jar!/path/to/2.xsd</jaxws:schemaLocation>
etc.
</jaxws:schemaLocations>
But that did not work.
What does work for my purposes is disabling schema validation in an
outbound interceptor.
I read through the code for
org.apache.cxf.interceptor.AbstractOutDatabindingInterceptor and
basically just reverse engineered this from the "shouldValidate()"
method
which checks on Message.SCHEMA_VALIDATION_ENABLED:
public final class SchemaValidationDisablingOutboundInterceptor
extends AbstractSoapInterceptor
{
public SchemaValidatingOutbountInterceptor() {
super(Phase.MARSHAL);
}
public void handleMessage(SoapMessage message) throws Fault {
for( Interceptor<? extends Message> interceptor :
message.getInterceptorChain() ) {
message.setContextualProperty(Message.SCHEMA_VALIDATION_ENABLED,
false);
}
}
}
