Javier,

no problem.
Anyway what you described sounds really strange to me.

Normally it should work with Java 5 like a charm, at least it does itfor me.

Lars

Lars,

I have corrected the problem: it was that I need to compile with Java
1.6and I was using Java
1.5.

Thanks a lot for your answers (and speed)

Javier,

please make sure your bean implements the MessageExchangeListener
interface.
"public class MyBean implements MessageExchangeListener" for example.

Then make sure you define this in your bean class as well:

@Resource
private DeliveryChannel channel;

@Resource
private ComponentContext context; // if you need the component context

I all of this is done without getting it to work then I am a little
curious about that.
Maybe it helps when you post both xbean.xml and your class (throw your
private things out of the bean before doing this).

Regards,
Lars

Thanks for answering so fast!

I believed that I was doing what you have said but I had a problem with

my

project configuration.

The problem that I have now is with:

@Resource
    private DeliveryChannel channel;

    public void onMessageExchange(MessageExchange exchange) throws
MessagingException {
        System.out.println("Received exchange: " + exchange);
        exchange.setStatus(ExchangeStatus.DONE);
        channel.send(exchange);
    }


Now I get a NullPointerException, when "channel.send(exchange)" is

executed.

My problem is that the DeliveryChannel "channel" is not initialized. Am

forgetting something (like something as "@Resource")?

Thanks again.

Hi,

where to put the bean class is clearly defined.
In your SU you can configure via xbean.xml:

<bean id="listenerBean"
class="org.apache.servicemix.bean.beans.ListenerBean"/>

This means that you have to place this bean class in your bean SU in a
package called:
  org.apache.servicemix.bean.beans
and with the name:
  ListenerBean

So if you use eclipse for developing the path should be this:
  <your project path>/src/org/apache/servicemix/bean/beans/

Hopefully this will help you,
Lars

Hi,

I am trying an easy example with the bean component (the same that can

be

find in http://servicemix.apache.org/servicemix-bean.html) but I do

not

know

where to put the bean class (in the example:
org.apache.servicemix.bean.beans.ListenerBean).
I have tried to put it directly in the classpath and in the service

unit

but

I get:
...
Configuration problem: Bean class [
org.apache.servicemix.bean.beans.ListenerBean] not found
...

I am developing using Eclipse, and I am launchin servicemix using
org.codehaus.classworlds.Launcher.

Thanks
