Internal server code is granted all permissions. These are covered by the AllPermission grant blocks to various parts of the server infrastructure code. Do not modify these entries.
Application permissions are granted in the default grant block. These permissions apply to all code not part of the internal server code listed previously. The Enterprise Server does not distinguish between EJB and web module permissions. All code is granted the minimal set of web component permissions (which is a superset of the EJB minimal set). Do not modify these entries.
A few permissions above the minimal set are also granted in the default server.policy file. These are necessary due to various internal dependencies of the server implementation. Java EE application developers must not rely on these additional permissions. In some cases, deleting these permissions might be appropriate. For example, one additional permission is granted specifically for using connectors. If connectors are not used in a particular domain, you should remove this permission, because it is not otherwise necessary.
