Before you begin
Java 2 security uses several policy files to determine the granted
permission for each Java program. The Java Development Kit provides the
PolicyTool tool
to edit these policy files. This tool is recommended for editing any policy
file to verify the syntax of its contents. Syntax errors in the policy file
cause an AccessControlException exception when the application runs, including
the server start. Identifying the cause of this exception is not easy because
the user might not be familiar with the resource that has an access violation.
Be careful when you edit these policy files.
See Java 2 security policy files for the list of available
policy files.

To use the
PolicyTool utility
with WebSphere Application Server for z/OS, choose one of the following two
options:
- Copy the policy files to another platform such as Microsoft Windows and
modify the files. To use this option, you must issue the FTP command to transfer
the files to the other platform, invoke the PolicyTool, and transfer
the updated files back to the z/OS system in binary mode.
- Invoke the PolicyTool that is supplied with the Software Development
Kit (SDK) installed on your z/OS system.
You must install
either the client or plug-ins component of WebSphere Application Server on
a workstation in order to access the PolicyTool. It is not currently
supported on the iSeries server.
