How to debug J2ME?

Dear all,
I am new to J2ME. I have wrote a Midlet and try to send message to a servlet, but not successful. I want to know can I debug a Midlet? Can I use System.out.println() in Midlet?
Or I need to write debug message to recordset? Can I use forte for java to debug it? Or need to display error message in alert?
Thanks a lot

Writing to System.out.println() is always a good starting point for debugging.
There are various J2ME/MIDP tools that support more robust debugging capablities.
Here are links to various tools available:
