How to capture Runtime.exec() output? doesn't seem to work?

Question

This is the first time I've used Runtime.exec();
Here's the code:
Runtime rt = Runtime.getRuntime();
            process = rt.exec(jobCommand);
            BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line=null;
            while((line=input.readLine()) != null) {
                 System.out.println("OUTPUT: " + line);
            int exitVal = process.waitFor();
        } catch(Exception e) {
             e.printStackTrace();
        }//end catchas you can see, this is just copied and pasted out of the standard example for this method.
When it gets to the line:
while((line=input.readLine()) != null)
it doesn't read anything. However, when i run the SAME exact command from the windows CMD prompt i get a ton of output.
what am i doing wrong here?
thanks.

No one can see what command you are talking about; you didn't post the commnd or even describe what output you expect to get.

What you are doing wrong is not providing the code you are using, the command you are using or enough information about what exactly you are doing.
No one can try to reproduce your problem based on what you posted.
