Remote debugging in java

Remote debugging is something most people doesn't need every day, but being able to debug an application deployed in another server is unvaluable. It saves a lot of time and effort making trial-and-error attempts to discover where is the problem and how to fix it.

Here i will show you how to do it in a few steps; lets say you have a JAR file called "application.jar":

Start the application enabling remote debbuging:

Start the application with the following command.
This command starts a server socket at port 8998 and broadcasts the debugging messages using JDWP (Java Debug Wire Protocol).

Configure Eclipse

•  Go to Run -> Debug Configurations
•  Create a Remote java Application
•  Configure the details:
•  Connection Type: Standard
•  Host: Server of the remote app
•  Port: Chosen when launching the jar (8998 in this example).
•  Check "Allow termination of remote VM"
•  Check Common->Debug if you want it on your favorites menu.

Click "apply" and...voi-la! you can now debug your application by launching this configuration!
