Hello,
I am trying to write a component which sends the message to the broker but I
am getting some exception.
javax.jbi.messaging.MessagingException: In not supported

public class MyComponent extends PojoSupport implements
MessageExchangeListener {
public void onMessageExchange(MessageExchange exchange)
throws MessagingException {
// TODO Auto-generated method stub
System.out.println("inside onMessageExchange ");
NormalizedMessage msg = exchange.createMessage();
exchange.setMessage(msg,"in");
msg.setContent(new StringSource("Hey! This is my ws-notification
message"));
done(exchange);
}
}
I have also attached the servicemix xml file. (servicemix_test.xml)
http://www.nabble.com/user-files/235943/servicemix_test.xml
servicemix_test.xml . Please help me.
Thanks,
Pradeep
