Hi there,

As far as I know there is no way to set execute permission by default on a newly created file. You might be able to change the permissions from within your Java program after creating it, though. Which version of Java are you using? In Java 7, try setPosixFilePermissions() in the java.nio.file class.

Out of curiosity, any particular reason you need execute permission? This is an unusual requirement. What files are you creating that need this?

Regards,

Clifford

i am writing a project under cloud Computing Design,,
and admin user can add new function to the server and i want to compile the function before adding to the server
in linux when we create a file,, execution permission is not as default, for this reason i cant run the file for compile

setPosixFilePermissions() did worked..

thanks man..

at last i have a question

this Solution "Set<PosixFilePermission> perms = new HashSet<PosixFilePermission>();"
is a OS Dependence or is universal Solution and work all right in all Operation System ????

This works only on POSIX-compliant systems. This means it will work on Linux, most other UNIX systems, etc, but not on Windows.
