Open an RDP file with Remote Desktop Connection

New to Java Forums. :D

I frequently remote into my home computer, and I'm writing an application to make life a little easier where that is concerned.

So far, the app pings my computer, and if it doesn't get a reply, it sends a "wake up on lan" "magic packet" to wake up the computer, then continues pinging (up to 4 more times) until it gets a response.

Once it gets a reply, I want to call an .RDP file, which is just a plaintext XML-style file that stores Remote Desktop Connection settings.

I know that in order to call a program, in this case RD, I just use this:

Code:

---

Runtime.getRuntime().exec("mstsc");

---

And that DOES open the program, but I'd like to open a specific FILE with that program. Any ideas?

(Note: To simplify it, just telling me how to open a .txt and force it to open in notepad.exe would be fine, as I assume it's the same idea. )
