Server.policy file

Question

The ejb I am developing is trying to delete the following file from a local filesystem (Linux SuSE 9.3 Pro) : /path/to/file/delete.me I get the following exception:
java.security.AccessControlException: access denied (java.io.FilePermission /path/to/file/delete.me delete)
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)
at java.security.AccessController.checkPermission(AccessController.java:427)
at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
at java.lang.SecurityManager.checkDelete(SecurityManager.java:990)
at java.io.File.delete(File.java:869)
I tried to modify the server.policy file adding the following line:
permission java.io.FilePermission "/path/to/file/delete.me", "delete";
but nothing changes, even when I restart the application server (don't know even if it is necessary to restart). I am using Sun Java System Application Server Enterprise Edition 8.1. Any help is welcome...
Thanks in advance

I think I solved the problem. At least I managed to delete the file :-)
First I had to add the following line to JRE's java.policy file:
permission java.io.FilePermission "/path/to/file/delete.me", "delete";Then I added the following entry to the server's server.policy file:
grant codeBase "file:${com.sun.aas.instanceRoot}/applications/j2ee-apps/MyApp-" {
  permission java.io.FilePermission "/path/to/file/delete.me", "delete";
};like described here:

I hope this could help to someone with the same problem
