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

daynok Jun 10, 2011 1:02 PM

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

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.
