Intellij IDEA remotely debug java console program

Question

I have a remote server with Java running to which i have SSH access. I am writing an app on the local machine, building it with maven. Is it possible to set the IDE Itellij IDEA to run my project remotely? The idea is : to build the jar, copy it to the server, and debug the process ( or something like that).

It would be nice of you to share the settings i need to setup.

Answer 1

This is what I usually do to debug my remote app.

1. Run the server on debug mode

   This can be adding this particular line when you run your application server

   -Xdebug -Xrunjdwp:transport=dt_socket,server=n,suspend=n,address=9999
   

   for JDK above 1.4, you can use this

   -agentlib:jdwp=transport=dt_socket,server=n,suspend=n,address=9999
   

   After that, run your application server

2. SSH Tunneling

   I'm not 100% sure that you can access to your application's port directly if you're using ssh connection (well, maybe there is a way ;) ). So, first we need to expose the port for debugging that we set on first step by running this command.

   ssh -f [email protected] -L 9999:personal-server.com:9999 -N
   

3. Setting up the IDE

   You can follow the step that @SSJVegito has said, which basically, is to point the debugger to the port 9999. Open the debug configuration in your Idea, then Change the circled value to 9999. Then, happy debugging :D
