running rosjava pub/sub tutorial as NodeRunner

edit

Hi there, I took a look at the rosjava https://rosjava.googlecode.com/hg/rosjava_tutorial_pubsub/src/main/java/org/ros/tutorials/pubsub/">pub and sub tutorials today and tried to get them to run through the NodeRunner class.

I thus created the below MyRobot.java file with the main, placed it into the folder with the [Talker|Listener].java files and successfully compiled it.

package org.ros.tutorials.pubsub;
import org.ros.node.NodeRunner;
import com.google.common.base.Preconditions;
import org.ros.node.Node;
import org.ros.node.NodeMain;
import org.ros.node.NodeConfiguration;
import org.ros.node.DefaultNodeRunner;
import org.ros.tutorials.pubsub.Talker;
public class MyRobot 
{
  public static void main(String[] args) 
  {
    NodeMain nodeMain =  new Talker();
    //        NodeConfiguration nodeConfiguration;
    NodeConfiguration nodeConfiguration = NodeConfiguration.newPrivate();
    NodeRunner nodeRunner = DefaultNodeRunner.newDefault();
    nodeRunner.run(nodeMain, nodeConfiguration);
    nodeRunner.shutdown();
  }
}

The problem however is that I am now NOT able to successfully execute it. I tried with "java MyRobot" command (in targer/classed folder) but all I am getting back is the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: MyRobot
Caused by: java.lang.ClassNotFoundException: MyRobot

Could not find the main class: MyRobot. Program will exit.

If anyone could tell me why the class is not being found I'd greatly appreciate it.

best, D.
