             Summary: Cached JAXB databinding 
                 Key: CXF-8450
                 URL: https://issues.apache.org/jira/browse/CXF-8450
             Project: CXF
          Issue Type: New Feature
          Components: JAXB Databinding
            Reporter: Mantas Gridinas
         Attachments: Creates_a_reordered_JAXBDataBinding_implementation_that_permits_expanding_internal_class_l.patch

Background: we use CXF 3.3.9 via apache camel 2.25

Our internal system provides single WSDL file every release which contains roughly 30 interfaces and produces about 3.2K classes. When using regular JAXBDatabinding implementation we found that it rescans the classes every time we attempt to create one of those interfaces endpoint when we use new instances of JAXBDatabinding. When we reuse an existing instance of JAXBDatabinding, there's a check in it that prevents expanding the class list in existing context:
{code:java}
// context is already set, don't redo it
if (context != null) {
    return;
}

{code}
and as a result, it crashes with the following error
{code:java}
org.apache.camel.RuntimeCamelException: org.apache.cxf.service.factory.ServiceConstructionException: Service class se.foo.schemas.bar.webservices.wsdl.BenefitInterface method getBenefit part {http://schemas.foo.se/bar/WebServices/wsdl}request cannot be mapped to schema.

{code}
I've attached the changes patch that would be made to existing JAXBDatabinding class to support the expanding internal cache. I'm sure that the cachedjaxbdatabinding breaks some existing concerns.

 

Looking through existing tests that refer to JAXBDatabinding class it seems I would have to duplicate quite a few of them. Is there a TCK that could be used for JAXBDatabinding implementations instead?
