I am trying to get the CXF BC working within my lwcontainer component, but
I'm having some problems, most likely due to my lack of webservices
experience. I am posting messages onto the NMR programatically, and then
reading them out of JMS within a lwcontainer for delivery to the outside
world. Everything seems to be working from the CXF BC side, however my
external CXF server doesn't seem to like the format of the message I'm
sending it. This might be due to the fact that I'm constructing the
jbi:message brute force via XSL. My webservice was created using CXF's
java2wsdl utility from the following 2 java source files.
WsMessageSink.java:
package com.initiatesystems.publisher;
public interface WsMessageSink
{
void onMessage(String message);
}
WsMessageSinkImpl.java:
package com.initiatesystems.publisher;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
public class WsMessageSinkImpl implements WsMessageSink
{
private static final Log log =
LogFactory.getLog(WsMessageSinkImpl.class);
public void onMessage(String message)
{
if (log.isDebugEnabled())
{
log.debug("onMessage: " + message);
}
}
}
Below is the error I'm seeing from the CXF server:

I am also seeing this coming from stdout/stderr within my ServiceMix
container, but I suspect its a side effect of the CXF server errors:

If anybody has suggestions or ideas what I'm doing wrong I would really
appreciate the help!
