How to execute external EXE?

**2bGeek** · 02-13-2009, 02:45 PM

Hi,

I'm trying to make a GUI so that it can run a third-party command-line exe.
the command that I'm trying to work on is as follows on netbeans:

clic mp3play.gd -i c:\test.mp3

where:
clic is the main exe.
mp3play.gd -i is the parameter
test.mp3 is the actual file, which is the user input.

I have tried using runtime class. but it doesn't seem to work..
Thanks in advance
Pls do help me out.

Runtime.exec returns a process. Do a 'process.join' on that to ensure the process has finished. Then you can get the InputStream and error streams for the process to see what happened. But looking at what you have, my guess is you are trying to do something like

Java Code:

Runtime.getRuntime.exec("clic mp3play.gd -i c:\test.mp3");

Which isn't going to work, because '\' is the escape character in java, so it's going to convert the '\t' in 'c:\test.mps' into a tab character. The OS will not find a file called c:{tab}est.mp3 and the clic command will fail.
