It doesn't work how?Are you catching exceptions and displaying them?

I do have one question, is "start" a builtin MS-DOS command, and so not a separate program? It's just that when you are in a command line, you're actually in a dos prompt. Some command are interpreted by the prompt. When a command is not a built in command, then an executable is searched. If no executable is found, you got an error. I think that Runtime.getRuntime().exec( "something" ) doesn't launch a dos prompt, and so if "something" is a built-in command, it won't execute.

And it's weird. I run the same code in 2 win2000 machine, one works fine, the other doesn't, Could you tell me why, did I miss some setting? Thanks a lot. Regards

The following should work on a system that has 'start' available.Process p = Runtime.getRuntime().exec("cmd /C start temp.txt");p.waitFor();

Hi there:No, It still not work. I got the same exception. I even import the registry from other machine on which my code works. but still get the same problem, it's really weird. Could anybody help me out? Thanks a lot. Regards

# 7

Is there any difference when you type 'start' on the 2 machines? Just to make sure 'start' refers to the built-in DOS command on both machine, and not to a script in one of them.PS: That's when commands such as 'which' are very handy (unix/linux command) :)

Actually, I test seven computers in my office only one works. They are all running win2000. I even imported the registry from the "lucky" one to my machine, but the problem stays the same.

On the contrary, at my home's machine it works both on win98/win2000.

It really don't make sense.

Help me out please!

# 9

Now I found a work-around. I copy the "start.exe" from my win98 machine to win2000 machine under the folder of winnt/system32, everything works fine. So now I think maybe the problem is the "start.exe" command. the buildin start.exe command doesn't work properly, or .....

So how can I configure win2000 to be proper environment to run that java code ?
