> Using Pojo Messaging annotations, Camel automatically uses the Type Converter system
to unmarshall XML messages to JAXB objects in the following scenario:
> {code:java}
> public class CamelPojoDemo {
> 	
>     @Produce(uri = "amq:camelpojodemo.reply")
>     private ProducerTemplate producer;
> 	
>     @Consume(uri = "amq:camelpojodemo.request")
>     public void trigger(UpdateMarketDataMessage message) {
>     	String result = "Processed prices: " + message.getMarketData().getPrices().size();
>     	producer.sendBody(result);
>     }
> }
> {code}
> However, handing the producer a JAXB object and expecting it to marshall it to XML before
sending it does not seem possible in the current API.
> I would like to propose to add the following method to the ProducerTemplate:
> {code}
>   /**
>      * Sends the body to the default endpoint after converting it to the given type
>      * <br/><br/>
>      * <p/><b>Notice:</b> that if the processing of the exchange failed
with an Exception
>      * it is thrown from this method as a {@link org.apache.camel.CamelExecutionException}
with
>      * the caused exception wrapped.
>      *
>      * @param body the payload to send
>      * @param type the type which the body should be converted to before sending
>      * @throws CamelExecutionException if the processing of the exchange failed
>      */
>     void sendBody(Object body, Class type) throws CamelExecutionException;
> {code}
> This would allow users to send a JAXB object and instruct Camel to use its Type Converter
system to marshall the object to XML:
> {code}
> producer.sendBody(jaxbObject, String.class);
> {code}
> Note: The sendBody, sendBodyAndHeader and sendBodyAndProperty methods are all overloaded
several times which could mean quite a number of new methods.
