Run program.exe from eclipse plugin project

Question

I am writing an eclipse-plugin witch run program.exe. I have added program.exe to plugin jar file. How can a execute this program?

public class Handler extends AbstractHandler {
    public Object execute(ExecutionEvent event) throws ExecutionException {
        Runtime.getRuntime().exec(/*What should I write here*/);
        return null;
    }
}

Answer 1

You can't run the program.exe from inside the plugin jar, so it needs to be extracted. In your plugin use:

Bundle bundle = Platform.getBundle("plugin id");

URL url = FileLocator.find(bundle, new Path("relative path to program"), null);

url = FileLocator.toFileURL(url);

This will find the program in the plugin jar and extract it to a temporary location (done by FileLocator.toFileURL).

Answer 2

You should just execute the program like you would in cmd, but now specify the whole path of the programs location.

Runtime.getRuntime().exec("C:\\your\\path\\program.exe");

In the Oracle documentation of the Runtime class you can see the acceptable inputs in exec().
