Directory Permissions problem when using mkdir() of the File class

Hello,

I hava a Java application that creates directories using the mkdir() method of the File class. This is in UNIX. when the directory is created by madir() it has drwxr-xr-x permissions string by default. As you can see the user has r/w/ex permissions, and the group has only r/ex permissions and does not have 'write' permissions. Our requirement is, when this directory is created, we must give permissions to the group also for writing.

Since mkdir() defaults to drwxr-xr-x, how can I set the peremissions to be drwxrwxr-x so that the group will also have write permissions when the directory is created.

Thanks

Two ways i can think of

1. set the umask of the shell in which the java app is running to 0002 (man umask)
2. Runtime.exec a chmod after the fact

No. Java is platform independent, so would have no platform-dependent way of altering file perms

I set the permissions using chmod 775  by Runtime.exe();
