>>>>The JDBC driver requires
>>>>>>>> permission java.net.SocketPermission "host:port", "connect";>>>>>>>>in the policy file of the application using the JDBC driver>>>>in the postgresql.jar file. Since the Socket() call in the>>>>driver is not protected by AccessController.doPrivileged() this>>>>permission must also be granted to the entire application.>>>>>>>>The attached diff fixes it so that the connect permission can be>>>>restricted just the the postgresql.jar codeBase if desired.David Daney
