Subject [jira] [Created] (CXF-5228) Rest client reports interface not visible for service interface
Date Thu, 22 Aug 2013 15:18:53 GMT
Christian Schneider created CXF-5228:

             Summary: Rest client reports interface not visible for service interface
                 Key: CXF-5228
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS
    Affects Versions: 2.7.6
         Environment: OSGi
            Reporter: Christian Schneider
            Assignee: Christian Schneider
             Fix For: 3.0.0, 2.7.7

When using a rest client in blueprint in OSGi I get the following stacktrace:
Caused by: java.lang.IllegalArgumentException: interface
is not visible from class loader

See this for the full trace:

I debugged into it and found that the true execption is hidden.
It happens in org.apache.cxf.jaxrs.client.JAXRSClientFactoryBean.createWithValues(Object...)

There is first tries to create the proxy using the classloader of the service interface. 

This fails as in the user classloader there is only the service interface but the proxy is
also create for the cxf Client interface. So it fails when resolving cxf Client.

This exception is swallowed and the context classloader is used to create the proxy. This
classloader is not set so it reports the user service interface is not visible. This is not
the root of the problem though.

I fixed this by using a ProxyClassloader that contains the user classloader and the classloader
of the JAXRSClientFactoryBean. So it then finds user classes as well as cxf classes.
