Simple XML router using CXF

[sha_cxf <Sh...@morganstanley.com>]

I want to write a xml message router using cxf but I am not very clear about
the internal working of cxf.

A sample scenario that I want to implement is something like this -

There are two services - ADD (hosted on host1:9000 and host1:9001) &
SUBTRACT (hosted on host2:9000 and host2:9001).

The router listening on host3:7777 would decide the target service for the
xml message (not bound to any schema) based on the xml message (using
xquery).

After deciding the target service it would decide on the specific
connection(host*:9000 or host*:9001) in say a roundrobin fashion.Then fire
that message to that service.

Receive a response from the service and pass it to the client.

How can it be done using CXF?

It is not easy to implement your requirement in CXF by hacking the 
interceptors.
Here is an example which support routing the message between the 
endpoints in CXF by xml message's version[1].
It may be helpful to you case.

The only way to do this is to use a jax-ws Provider based endpoint.    
Making it Provider<SOAPMessage> would give you the whole soap message  
that you could then forward onto something else or mangle it or  
whatever.

Thanks Willem.

But is there any way to implement this in CXF. I have to prepare a prototype
in CXF alongwith one in CAMEL.

To be precise, any pointers on how to invoke a method on a service when the
incoming request format is not bound to any schema/format or how can I make
CXF relate all xml messages (with different schemas) to one particular
method in the service (say handleMessage).

Hi

It is easy to implement the such a content base routing by using Camel[1].
And it also provide a way to implement the load balance[2] .

BTW, You could also leverage the Camel's mediation by using the 
CamelTransport[3] in CXF.

These requirements look like you would benefit from an ESB like Mule or
ServiceMix.  For the proprietary BEA AquaLogic Service Bus, for example,
the tutorials here[1] are very similar to your requirements.
