I'm not familiar with MyEclipse. It is possible to use a debugger on a running ES5 server, and I can get those instructions for another IDE if you like - perhaps it will be close enough. In the meantime, have you read Debugging Extensions?

I just noticed that you are learning ES4, not ES5. The Debugging Extensions article is still mostly correct.

I found my notes on setting up the server side IDE for debugging. These notes are for IntelliJ, and Eclipse should be similar. I assume that MyEclipse will also be similar.
----------------
The key is setting up a Debug Launch Configuration of the type "Remote Application", and choosing the port as specified in your ElectroServer startup.

Of note:
• The port is 8000 for my example.
• In both IDEs you would want to pick your server project as the location for the IDE to find source for the program under debug.
• The startup parameters for the vm (-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,ad dress=8000) need to go into the Additional JVM Parameters section of the ES Admin, or if you're using a custom start script, just in the main Java execute line.
• If you have something you want to debug on server startup (like a data populator or something), and are worried about connecting your debugger in time, you can change the "suspend=n" in the above line to "suspend=y" - this will prevent the VM from actually starting until your debugger has connected.
----------------------

Since you are using ES4, not ES5, you don't have a place in the web admin to add startup commands. You will have to start ES4 using a java -jar command line script (or batch file if you are on Windows).
