    How to get original message?

    Alex Sokolov Newbie

      Hi,

      I run into problem getting original body/message from route on exception/completion.

      The flow is like:

      - get message from source

      - transform

      - split

      - an exception occurcs during processing parts

      - catch exception and log original message as it came from source

      Here is the test describing this behaviour:

       

      public class TestSplitterAggregator extends CamelTestSupport {

       

          @Produce(uri = "direct:start")

          protected ProducerTemplate templ;

       

          @Test

           public void testFreshTrades() throws Exception {

               templ.sendBody("ORIGINAL");

           }

           

          @Override

          protected RouteBuilder createRouteBuilder() {

              return new RouteBuilder() {

                  public void configure() {

                       onCompletion().process(new Processor() {

                               @Override

                               public void process(Exchange exchange) throws Exception {

                                    System.out.println("Original Body after completion: " + exchange.getUnitOfWork().getOriginalInMessage().getBody());

                               }

                          });

       

                       onException(Exception.class).handled(true)

                       .process(new Processor() {

                               @Override

                               public void process(Exchange exchange) throws Exception {

                                    System.out.println("Original Body after exception: " + exchange.getUnitOfWork().getOriginalInMessage().getBody());

                               }

                          });

       

                      from("direct:start").process(new Processor() {

                               @Override

                               public void process(Exchange exchange) throws Exception {

                                    exchange.getIn().setBody("Processor1");

                                    System.out.println("Processor1: Original Body " + exchange.getUnitOfWork().getOriginalInMessage().getBody());

                               }

                          })

                          .split().method(new Splitter(), "split").stopOnException()

                          .process(new Processor() {

                               @Override

                               public void process(Exchange exchange) throws Exception {

                                    if ("Part2".equals(exchange.getIn().getBody(String.class)))

                                         throw new Exception("Exception!");

                                    System.out.println("Processor2: Original Body " + exchange.getUnitOfWork().getOriginalInMessage().getBody());

                                    exchange.getIn().setBody("Processor2");

                               }

                          }).end();

                  }

              };

          }

       

           public static class Splitter {

                public List split() {

                     return Arrays.asList(new String[] {"Part1", "Part2", "Part3"});

                }

           };

      }

      -


      The output:

      Processor1: Original Body ORIGINAL

      Processor2: Original Body Part1

      Original Body after exception: Part2

      Original Body after completion: Part2

      -


      used Camel 2.6

      Is there a way to get original message (e.g. ORIGINAL) after route completed/failed?
