[mule-user] Run Echo Mule example in RAD

[sg...@aol.com]

My experience with Mule is for a few hours. I am trying to run the Echo Mule example.
 
I created a Java project (not web, or J2EE) project in RAD 6.0 with JDK 1.4.
I created a package com.trial and under which I have two classes namely EchoComponent.java and EchoService.java have. I also have echo-config.xml under com.trial.

I copied all the source codes from Mule's Echo example.

I have mule1.4.3.jar, mail.jar and activation.jar in classpath for this project. I am not using the Axis web-service version.

My question:
How can I run it from RAD, instead going through command prompt? There is no Java main class, or client class to run. What do I need to do to run this so see the output?

Any help will be appreciated on how to run my first Mule example in RAD.

Should the echo-config.xml file be placed outside of package?

What I observed is, there is no tutorial/book available on this outside of Mule.org. 

Any suggestion on how to get feet wet with Mule will be appreciated.
Sam

Two options:

1) Use/start Mule Server programatically

http://mule.mulesource.org/display/MULE/Running+Mule  (2/3 of the way down this page it says "You can also start a mule server from your code by using one of -" and has an example.

2) http://mule.mulesource.org/display/MULE/Embedding+Mule+in+a+Java+Application

This is my first attempt using Mule. I want to run it from RAD (kDK 1.4) as a Java app and want to run Echo example. I copied all the necessary java files for Echo example, xml and created a client. I get following error when I run the client, which is Java main class:

org.mule.umo.provider.DispatchException: Failed to route event via endpoint: MuleEndpoint{endpointUri=vm://my.object, connector=VMConnector{this=600dd30d, started=true, initialised=true, name='connector.VM.0', disposed=false, numberOfConcurrentTransactedReceivers=4, createMultipleTransactedReceivers=true, connected=true, supportedProtocols=[vm], serviceOverrides=null}, transformer=null, name='endpoint.vm.my.object', type='sender', properties={}, transactionConfig=Transaction{factory=null, action=NONE, timeout=30000}, filter=null, deleteUnacceptedMessages=false, initialised=false, securityFilter=null, synchronous=null, initialState=started, createConnector=0, remoteSync=null, remoteSyncTimeout=null, endpointEncoding=null}.

I copied all the source codes from Echo example and echo-cinfig.xml is in the same directory as the java class files (all under one package). I have the necessary jar files.

Following is the client Java code that I am trying to run, but getting exception:

public class MyClient {

 public static void main(String[] args) {  
  try {
   MuleServer server = new MuleServer("mule-config.xml");

   server.start(true);

   MuleClient client = new MuleClient();

   UMOMessage message2 = client.send("vm://my.object", "Some more data", null);
  } catch (ConfigurationException e) {
   e.printStackTrace();
  }catch(Exception e){
   e.printStackTrace();
  }
  
 }
}

Any help will be appreciated.

Is your "mule-config.xml" file the same as the "echo-config.xml" one?

If yes, this configuration does not define any component listening on "vm://my.object", so what do you expect by sending a message to this queue?
