Hi,

I need to call a shell script from my Java code. That works. But I am not able to create a file using 'touch' (in Linux). The shell script has the touch command and its not creating a new file.

I used policytool to set teh policy to AllPermissions, even tried to set teh permission to FilePermission but nothing worked.

What could be the problem.

regards,
vijay.

You say that the shell script contains the "touch". If you run the shell script in standalone mode (i.e. from command line, not from your program), does the "touch" work? Maybe the user you are running the Java program as doesn't have permission to create a file in the directory. there are several possibilities here, but first let us know if the script works by itself.

So instead of calling a shell script to create a file, why not something simple like
