Runtime.exec() method Posted: May 10, 2005 9:27 PM

I am trying to run following code...

String command = "batch.bat";
Process child = Runtime.getRuntime().exec(command);

When the batch-file contains some command that doesn't involve any file operation then the code is running fine.
But when it contains some commands related to file creation/modification , then the code is getting hanged.

I have used the following command in batch-file...

echo inside batchfile
pause
edit test.dat
pause

first line is getting executed but program gets hanged when it comes to second line. The batch-file is running fine when it is being executed from commandline. Can anyone solve this problem?

Just a thought:
Try executing "cmd /C batch.bat"

This solved several problems I had in the past.

Are you trying to do this in an applet?

If not, have you tried the same batch file with the same user account on the command line?
