Running external programs

[toffie]

i know that to run an external program you have to use the Runtime.exec() method, but i'm having some difficulty with it. i've created a runtime environment variable using the getRuntime() method and used this to call the exec() method, specifically the exec(String command, String[] environment, File dir) method but when it executes it gives an IOException that's something about the String command and error=0 (i can't recall the exact message)

So my question basically is, if i'm doing it wrong, how do u implement the Runtime class with the exec method and what exactly is the String command ie the DosPrompt cmd to run the program or what?
