java.lang.Runtime.getRuntime().exec(command);
Check the "exec" method. It can take several forms, but I typically use this one where "command" is a String.
java.lang.Runtime.getRuntime().exec(command);
Also, you may need to return a Process to get output depending on the app you launch. exec runs in a new process space (memory etc), so don't think it's related to a console and System.out.
java.lang.Process p = java.lang.Runtime.getRuntime().exec(command);
Then you can capture it's output with getOutputStream() etc.
I've moved away from IDE's in Java. I prefer notepad and a dos prompt. Inserting resources sounds like an IDE function. You did say that you use J++; try its "Help".
