Constructor Detail

BasicServer

public BasicServer(org.w3c.dom.Element rootElement,
                   java.io.File fedoraHomeDir)
            throws ServerInitializationException,
                   ModuleInitializationException

Method Detail

initServer

public void initServer()
                throws ServerInitializationException

Description copied from class: Server

Performs any server start-up tasks particular to this type of Server.

This is guaranteed to be run before any modules are loaded. The default implementation does nothing.

Overrides:

initServer in class Server

Throws:

ServerInitializationException - If a severe server startup-related error occurred.

shutdownServer

public void shutdownServer()
                    throws ServerShutdownException

Description copied from class: Server

Performs shutdown tasks for the server itself.

The default implementation simply calls closeLogger() - it should be overridden in Server implementations that tie up additional system resources.

This should be written so that system resources are always freed, regardless of whether there is an error. If an error occurs, it should be thrown as a ServerShutdownException after attempts to free every resource have been made.

Overrides:

shutdownServer in class Server

Throws:

ServerShutdownException - If a severe server shutdown-related error occurred.

getRequiredModuleRoles

public java.lang.String[] getRequiredModuleRoles()

Gets the names of the roles that are required to be fulfilled by modules specified in this server's configuration file.

Overrides:

getRequiredModuleRoles in class Pluggable

Returns:

String[] The roles.

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception
