in your java class, all you have to do is double click on the code where you want to set a break point(on the left side).
 (make sure you see a grey dot when you double click),
then stop the server and restart the server in DEBUG mode.

You can also refer to Eclipse Help.
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.jdt.doc.user/concepts/cbrkpnts.htm

ps: All the experts, administrators, moderators and page editors are members who volunteer their time to resolve questions and various issues that come up at EE, none of them get paid. There are times where none of the experts are available, this may due to different time frame (like me and David are at South East Asia), or may be busy on thier own work or ...etc. But all the experts at EE will try their best to help solving the questions. Hope you understand. :)
