Any good sources for using Apache-cxf/jax-rs to pass an object to a rest service? Looking for help

I am currently passing an object to my Apache CXF Rest client and it is not getting through. Relevant stack trace below:

cxf.interceptor.Fault: Could not send Message. at cxf.interceptor.MessageSenderInterceptor$MessageSenderEndingInterceptor.handleMessage(MessageSenderInterceptor.java:xxx)
at cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorC开发者_高级运维hain.java:yyy)
at cxf.jaxrs.client.ClientProxyImpl.doChainedInvocation(ClientProxyImpl.java:zzz)
at cxf.jaxrs.client.ClientProxyImpl.invoke(ClientProxyImpl.java:qqq)

Any suggestions of things to look into for this type of problem to trace into this or sources of reference information on what can go wrong with jax-rs?

Fixed it, turns out I had an unresolved server in a configuration file.
