[servicemix-user] Custom Component Question

[Julio Faerman]

Hi,

I am doing a simple InOut component to servicemix.
I want it to receive a string as a property in the inMessage and return the same string in the outMessage.
The problem is that client.sendSync() freezes and client.send() returns null, so i cannot get the output message.
Can anyone help me to understand what is going on ?

Code follows:

------- Component --------
public class HelloComponent extends OutBinding{
    protected void process(MessageExchange ex,
                           NormalizedMessage inmsg) throws
            MessagingException {
        ...
            NormalizedMessage out = ex.createMessage();
            out.setProperty("myString",inmsg.getProperty("myString"));
            ex.setMessage(out,"out");
            // canot call done(ex), as it is InOut, right ??  
        ...
}

------- Client --------
...
       InOut exchange = client.createInOutExchange();
      
       NormalizedMessage message = exchange.getInMessage();
       message.setProperty("name", "James");
       message.setContent(new StreamSource(new StringReader("<hello>world</hello>")));
      
 //      client.sendSync(exchange);      /** This blocks forever **/
//        client.send(exchange);            /** This returns null **/

       NormalizedMessage outmessage = exchange.getOutMessage();
...
------- Config --------
  <!-- the JBI container -->
  <sm:container spring:id="jbi" useMBeanServer="true" createMBeanServer="true" dumpStats="true" statsInterval="10">
    <sm:activationSpecs>
      <!-- Route the event to a trace component that just outputs the event to the console -->
      <sm:activationSpec componentName="hello" service="my:hello">
        <sm:component>
          <bean xmlns="http://xbean.org/schemas/spring/1.0" class="jm.jbi.HelloComponent"/>
        </sm:component>
      </sm:activationSpec>
    </sm:activationSpecs>
  </sm:container>
  <bean id="client" class="org.servicemix.client.DefaultServiceMixClient">
    <constructor-arg ref="jbi"/>
    <constructor-arg>
      <sm:activationSpec destinationService="my:hello"/>
    </constructor-arg>
  </bean>

What i did wrong ?

Thnx,
Julio
