Problem with Runtime.exec()
Hi all,
I want to get a list of a directory with dir command (windows Vista). I write:
Runtime.getRuntime.exec("cmd.exe /C dir " + MyPath);
but the command can't find the specified path for dir. My question is that how we can pass an argument for command line's programs like dir, copy,etc?

Yes, actually it is:
Runtime.getRuntime().exec().
I made a mistake in posting.
What is the problem?

Why don't you just use File?
But, did you use the full path? Or did you use a partial path, in which case, your "current path" is probably not what you thought it was.

I ue the full path. I know that I can do it with File, but I want to know how to do with exec().

Did you check the output is correct, trying to write into a stream? And also the best way is, use a command string array. Check overloaded functions of exec().

What happens if you leave off the cmd.exe /C and start the comand with dir?
Have you tried the exec() with other commands and gotten them to work?

It solved. If a program generates output or error, you should get the stream and write it immediately.
I read the javaworld article, thanks Masijade  |

Might need to have something like this ("cmd.exe /C dir """ + MyPath + """") had a similar issue with vbscript today, damn """" and spaces. This may not be exact but might help with your problem. |
