> Hi
> I encountered problems regarding message routing to the camel service engine and
> back to the jbi NMR again. The information about the ("initial") called
> operation on a endpoint is lost while communicating with camel.
> see also
> http://www.nabble.com/Possible-Solution-to-a-camel-serviceengine-problem-or-only-a-bad-workaround---tf4645158s12049.html
> IMHO there are three different strategies to solve this problem:
> (thanks Guillaume pointing me to them ;-) )
> * (1) DSL - API call within the RouteBuilder 
>   It's currently not possible to do this because the JbiEndpoint doesn't have
>   methods to set the operation.
>   Sample:
>   --- 8< ---
>   String toUri = "jbi:endpoint:xxx";
>   Endpoint endpoint = getContext().getEndpoint(toUri);
>   if (endpoint instanceof JbiEndpoint) {
>     		
>   	 JbiEndpoint jbiEndpoint = (JbiEndpoint) endpoint;
>      //not possible
>      jbiEndpoint.setOperation(operation);
>     		
>   } 
>     	
>   from(fromUri).to(toUri);
>   --- 8< ---
> * (2) URI - Setting the operation within the endpoint URI. 
>   This option specifies the operation within the given endpoint URI. It's clear
>   which operation should be called but you always have to define the operation
>   for a routing.
>   --- 8< ---
>   String toUri = "jbi:endpoint:xxx?operation=process";    	
>   from(fromUri).to(toUri);
>   --- 8< ---  
> * (3) Copying the information
>   This option copies the operation information from the "from-"Endpoint to the
>   "to-"Endpoint. This is a simple solution if you want to call the same
>   operation on all endpoints involved.
> I think option 2 and 3 should be applied. Option 2 overrides option 3. If you
> specify a direct operation information within your URI this one is used.
> Kristian
> ps: option 2 and 3 are available as patches within the attached file
