    camel cxf producer to cxf-nmr consumer  java.lang.NullPointerException

    Dana Shaw Newbie

      I've been trying to get two separate bundles to communicate via a nmr endpoint using a camel cxf producer.  I have been working on this all week and so far I can't get it to work.

       

      I can however all the nmr endpoint just as in example cxf-camel-nmr without issue so I know that bundle is ok.  Seriously this is a super simple hello world prototype and I can't get it to work. 

       

      Any help or suggestions would be awesome!!

       

      Env: Java 1.5

      Apache Servicemix 4.3.2

       

      In servicemix I have two separate osgi bundles.    I am unable to get my camel cxf producer to successfully call the nmr endpoint and have zero clue on how to fix.

       

       

      Bundle #1 cxf-nmr //consumer

            • 3. Re: camel cxf producer to cxf-nmr consumer  java.lang.NullPointerException
              Willem Jiang Master

              Hi,

              Please take a look at this exception. Camel that you used can't turn a CxfPayload message into StreamSource.

              org.apache.camel.InvalidPayloadException: No body available of type: javax.xml.transform.stream.StreamSource but has value: org.apache.camel.component.cxf.CxfPayload headers: []body: [ [<m:sayHi xmlns:m="http://cxf.examples.servicemix.apache.org/">
              <arg0>foobar</arg0>
              </m:sayHi>]] 
              

              I think you can just use the MESSAGE instead of PAYLOAD data formate to pass the message to the nmr endpoint.

               

              Willem

                Thanks for the hint Willem,

                Yea I thought for some reason that it had to be payload, message did the trick.  Whohoo got hello world up and running lols
