Converting between original data formats and XML

Issue

After reading up on Apache Camel and JBoss Fuse, I'm trying to implement a route to do the following, but I'm not exactly sure what would be the best (most Camel-like) way of doing it.

 Read legacy data in original format (A) from MQ -> Convert to XML -> Call Web Service
               -> Convert response (XML) to original format (B) -> Place message on output queue

The problem is with the conversions to/from original format and XML. There seems to be a variety of ways to do this in Camel. I've looked into using a bean to do the conversion, as well as creating an original DataFormat but I have not implemented anything yet.

• What would be the most Camel-like way of solving this?
