[mule-user] Unable to run Echo example from RAD

[sg...@aol.com]

New to Mule. Want to run Echo example of Mule in RAD.
Created a Java project (not J2EE) in RAD. Copied EchoComponent.java, EchoService.java in a package. Inside the same package in the same level, I have mule-config.xml and echo-config.xml - which are the same. In fact, echo-config.xml is copied into mule-config.xml (as I do not know if mule-config.xml is also necessary).

Have all jar files from lib and opt directory of Mule in classpath.
Using JDK 1.4 in RAD.

I wrote a Java client (main class) and inside the same package as other two Echo.. java classes.

Client code is:

import org.mule.MuleServer;
import org.mule.config.ConfigurationException;
import org.mule.config.builders.MuleXmlConfigurationBuilder;
import org.mule.extras.client.MuleClient;
import org.mule.umo.UMOMessage;
import org.mule.umo.manager.UMOManager;

public class TestClient {

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

   server.start(true);
   MuleClient client = new MuleClient();
   UMOMessage message2 = client.send("vm://echo", "Some more data", null);
  } catch (ConfigurationException e) {
   e.printStackTrace();
  }catch(Exception e){
   e.printStackTrace();
  }
  
 }
}

Get error in RAD console as:

log4j:ERROR Could not find value for key log4j.appender.stdout

log4j:ERROR Could not instantiate appender named "stdout".

log4j:WARN No appenders could be found for logger (org.mule.MuleServer).

log4j:WARN Please initialize the log4j system properly.

You have a jar conflict with libraries in your project. Ensure Mule's are coming first, including any bundled with Mule:
