Hi,

Can someone tell me a bit more about Java Policy Files?

What is contained in them apart from Grant Entries?

Thanks,
Dom

Dom,

A nice explanation can be found at:

Java 2 security policy files

The J2EE 1.3 specification has a well-defined programming model of responsibilities between the container providers and the application code. Using Java 2 security manager to help enforce this programming model is recommended. There are certain operations that are not allowed in the application code because such operations interfere with the behavior and operation of the containers. The Java 2 security manager is used in the product to enforce responsibilities of the container and the application code.
This product provides support for policy file management. There are a number of policy files in the product, which are either static or dynamic. Dynamic policy is a template of permissions for a particular type of resource. There is no relative codebase defined in the dynamic policy template. The codebase is dynamically calculated from the deployment and run-time data.
