The Administration Console provides an interface for administrative functions. If the Administration Console is not accessible, check the following:
The server must be running before the Administration Console can be accessed.
Review the information in Did the Server Start? to determine if the server is running.
The default port number for the Administration Console is 4848. However, it could be running on a different port number than expected, either because it was intentionally installed there, or because that port was in use when the server was started.
Refer to Was the Server Started at the Expected Port? for guidelines on verifying the port on which the Administration Console is running. Be sure to enter the correct port number and HTTP protocol when invoking the Administration Console.
The Security Manager is not optional; it must be enabled in Enterprise Server. Because there is no configuration interface in Enterprise Server for disabling the Security Manager, it can only be disabled when you directly modify the domain.xml configuration file in such a way that the following line is removed or commented out:
Verify that the -Djava.security.policy=yourPolicy option is present in the domain.xml file.
