> Hi,
> chaining 2 cxfrs endpoints in a route reveals 2 problems :
> - proxy-client method choice in producer (CxfRsProducer.findRightMethod) is way too restrictive : the choice is based on the name and the exact type of the parameters. As a consequence, if parameters  type transmitted are compatible (i.e. extend the signature parameter types) with the method signature but are not the very ones of the signature, the operation will not be found.
> That problem occurs when you chain 2 cxfrs endpoints having an InputStream parameter since cxf uses DelegatingInputStream to handle received InputStreams.
> That problem may also occur for any ".to()" cxfrs endpoint if the message body uses subtypes of the parameters.
> - transmitting Content-Type header from camel to CXFRS request in DefaultCxfRsBinding may cause trouble for multipart messages : actually, if Content-Type contains a boundary defintion (which is the case when you chain cxfrs endpoints), that definition will be included into the Content-Type transmitted (in addition with the one generated during binding). That throws an exception since the "old" boundary is not used in the transmitted message. NB : header propagation was not enforced in 2.13.2 but it is enforced in head.
> I developped a JUnit test that shows such failures in the case of a cxfrs endpoint chaining, and some code that prevents them. I am going to submit them on github.
> Regards
