Issue with Camel

[Ritwick <ri...@gmail.com>]

Hi, 
I am new to Camel and am facing an issue with a route I need to setup. It
will be great if someone can either guide me to the correct forum or better
still rectify the issue I am facing. 
Here is what I need to do - expose a restlet endpoint to accept data; use
this data as input to an external SOAP web service and send back the
response in JSON format back to the caller... 
Here is what I have done...however, I am getting the following error while
Camel tries to call the Web Service...can anyone guide me here? Thanks.

Re: Issue with Camel

[Ritwick <ri...@gmail.com>]

I was able to get this (Restlet -> CXF SOAP web service call) to work. Just
had to make sure that the following line was
there...exchange.getIn().setHeader("org.restlet.http.headers", "");The
restlet headers was actually causing the route to fail with the
ClassCastException - unable to convert from org.restlet.http.Parameter to
java.lang.String.In order to figure out the issue I had to configure the CXF
endpoint with "loggingFeatureEnabled=true". In the additional log that CXF
then provided me, I found that the only place where the request to the CXF
endpoint looked restlet-ish was in the header...once I removed that, it
worked like a charm...
