The client/server design of the Java debugger allows you to launch a Java program from computer on your network and debug it from the workstation running the platform. This is particularly useful when you are developing a program for a device that cannot host the development platform. It is also useful when debugging programs on dedicated machines such as web servers.
Note: To use remote debugging, you must be using a Java VM that supports this feature.
To debug a program remotely, you must be able to launch the program in debug mode on the remote machine so that it will wait for a connection from your debugger. The specific technique for launching the program and connecting the debugger are VM-specific. The basic steps are as follows:
When setting up the remote launch configuration there are a few items to take note of:
Certain Java VMs support another way of starting a remote debug session. In this alternative connection type, the debugger is launched first. The debugger then waits and listens for the VM to connect to it. To debug this way, you must properly configure and launch a remote debug session, then launch the VM, specifying the location of your waiting debugger.
