The JDT includes a debugger that enables you to detect and diagnose errors in your programs running either locally or remotely.
The debugger allows you to control the execution of your program by setting breakpoints, suspending launches, stepping through your code, and examining the contents of variables.
The debugger has a client/server design so you can debug programs running remotely on other systems in the network as well as programs running locally on your workstation. The debugger server runs on the same system as the program you want to debug, which can be on your workstation (local debugging) or a system that is accessible through a network (remote debugging).
