Did you install JBoss, using the JEMS installer? Just this past week, we had a discussion about this where it turned out that JEMS installer does not configure the JNDIView ( http://www.jboss.com/index.html?module=bb&op=viewtopic&t=133889).

For JNDIView to be available, you will have to download the JBoss zip archive. Unzip it to some location (which does not contain a space in its folder name Ex: D:\JBoss), set JAVA_HOME and start the server.

My intention of asking you to post the contents of the jndi tree was to see what the datasource is being bound to. If re-installing JBoss, is not an option for you, can you try out the following piece of code from the client and post the output?

 public static void main(String[] args) {
  | 
  |        try {
  | 
  | 		InitialContext ic;
  | 		Object ds = ic.lookup("MySqlDS"); 
  | 		Class[] interfaces = ds.getClass().getInterfaces();
  | 		System.out.println("Implemented interfaces: ");
  | 		for (int i = 0; i < interfaces.length; i++) {
  | 			System.out.println("*** " + interfaces);
  | 		}
  | 	}......
  | 	//other stuff
  | }

Let's see if this output gives us some clue.
