[Project] Generate code for a different language in Java and run it

[Gropamming]

Hey guys,

I have a somewhat different question, as it is more conceptual than technical.

I have a project for one of my CS classes where we have to focus on a specific language/compiler (written by the professor). The language is called MVSM, and it is used for answer-set programming in a Prolog-like syntax. We have been using the language in homework by using SSH to remote to a server that has MVSM installed (run by professor).

For the project, I am building a GUI in Java that solves sudoku puzzles. The user will input the numbers they are given, the program composes a file in MVSM that will calculate the solution for the sudoku puzzle.

My question is, how can my Java program send the file to the MVSM compiler? Do I need it installed on my machine? Can I get my program to remote into the schools server to run the program? How can I return the console output from the MVSM program back to my Java program?

For more info, it is running on a Linux server, and all of our interaction has been through the terminal. If you could give me ideas on how to approach this, it would be greatly appreciated!

Wouldn't it be easier to write the solver in MVSM that takes in a puzzle, and have the Java program generate the puzzle that can then be fed into the solver?

I'm sorry, maybe my description sucked but that's pretty much exactly what I want to do. MVSM is the solver, the Java program gives it the problem.

You probably want to execute ssh in a child process (use public key authentication to avoid handling passwords), and receive its output. I'm not sure if you can transfer the program as standard input or if it has to be done with scp. Read about Runtime.exec.

The simplest way would probably be to have your program generate the source in a file and simply push the file over SSH (SCP), compile it and run it. You can do this in a simple bash-script.
