JAVA:open file with different credentials

Is it possible to access a开发者_如何学JAVA file (read/write/delete/move...) using different credentials then the one the logged in user?

Not directly from the JVM, no.

But under Windows, you could do exec() with a RunAs command, and under Unix/Linux/OS X you could do exec() with sudo. Though you may end up getting prompted for the password.

What's relevant is not the logged in user but the user under which the process is running - these are not necessarily the same.

However, running a process under a different user ID is very OS-specific, and there is no Java API for it. Besides, it would have to be done when the JVM starts up, as I do not think any OS allows a process to switch its user ID.

If it is available as a file share you can use jcifs
