camel-cxf: unwrapped style web service returning empty body when schema-validation-enabled=true

[chiochuan]

Dear team,

could you help me for below issue?

i trying to read the body response for the web service but encounter below exception.

Based on the test, these only happen for unwrapped style web services.

i have tried with wrapped style and there is no issue for that.

FYI, this is only happen for jboss release, e.g 2.17.0.redhat-630XXX, but when i try wth camel 2.17.0, there are no issue.

Not sure if this is a bug or mistake on my end.

Attach is the test case.

You are using PAYLOAD and by default CXF does not do schema validation. If the schema validation is enabled, then CXF uses validation in databinding on JAXB like when marshal/unmarshal. Hence, with PAYLOAD the schema validation does not work.

I not sure if that really correct, but when i try to response with wrong response, CXF did throw error.
