Class ServerManager

java.lang.Object
  org.apache.synapse.ServerManager

public class ServerManager
extends Object

This is the core class that starts up a Synapse instance.

From the command line scripts synapse.sh and synapse-daemon.sh (though the wrapper.conf) the SynapseServer is invoked which in turn calls on this to start the instance

When the WAR deployment is used, the SynapseStartUpServlet servlet calls on this class to initialize Synapse.

This is the entry point for starting an Synapse instance. All the synapse related management operations are exposed through this class.

Constructor Summary

ServerManager()
Construct a server manager.

Method Summary

ServerState	endMaintenance() Ends server maintenance resuming transport listeners, senders and tasks.
ClassLoader	getClassLoader() Returns the context class loader of the original thread.
ServerConfigurationInformation	getServerConfigurationInformation() Returns the ServerConfigurationInformation, if the system is initialized and if not a Runtime exception of type SynapseException will be thrown
ServerContextInformation	getServerContextInformation() Returns the ServerContextInformation, if the system is initialized and if not a Runtime Exception of type SynapseException will be thrown
ServerState	getServerState() Retrieves the state of the server.
ServerState	init(ServerConfigurationInformation serverConfigurationInformation, ServerContextInformation serverContextInformation) Initializes the server, if we need to create a new axis2 instance, calling this will create the new axis2 environment, but this won't start the transport listeners
boolean	isInitialized() Has server manager been initialized ?
ServerState	shutdown() Shuts down the Server instance.
ServerState	start() Starts the system, if the system is initialized, and if not a Runtime exception of type SynapseException will be thrown
ServerState	startMaintenance() Put transport listeners and senders into maintenance mode.
ServerState	stop() Stops the system, if it is started and if not a Runtime exception of type SynapseException will be thrown
ServerState	stopGracefully(long maxWaitMillis) Perform a graceful stop of Synapse.

ServerManager

public ServerManager()

Construct a server manager.

Method Detail

init

public ServerState init(ServerConfigurationInformation serverConfigurationInformation,
                        ServerContextInformation serverContextInformation)

Initializes the server, if we need to create a new axis2 instance, calling this will create the new axis2 environment, but this won't start the transport listeners

Parameters:

serverConfigurationInformation - ServerConfigurationInformation instance

serverContextInformation - ServerContextInformation instance

Returns:

ServerState - State of the server which is ServerState.INITIALIZED, if successful

shutdown

public ServerState shutdown()

Shuts down the Server instance. If the Server is stopped this will shutdown the ServerManager, and if it is running (i.e. in the STARTED state) this will first stop the ServerManager and shutdown it in turn.

Returns:

the state after the shutdown, ServerState.UNDETERMINED

start

public ServerState start()

Starts the system, if the system is initialized, and if not a Runtime exception of type SynapseException will be thrown

Returns:

the state of the server after starting, for a successful start ServerState.STARTED

startMaintenance

public ServerState startMaintenance()

Put transport listeners and senders into maintenance mode.

Returns:

the state of the server after maintenance request, for a successful execution ServerState.MAINTENANCE

endMaintenance

public ServerState endMaintenance()

Ends server maintenance resuming transport listeners, senders and tasks.

Returns:

the state of the server after maintenance request, for a successful execution ServerState.MAINTENANCE

stop

public ServerState stop()

Stops the system, if it is started and if not a Runtime exception of type SynapseException will be thrown

Returns:

the state of the system after stopping, which is ServerState.STOPPED for a successful stopping

stopGracefully

public ServerState stopGracefully(long maxWaitMillis)

Perform a graceful stop of Synapse. Before the instance is stopped it will be put to maintenance mode.

Parameters:

maxWaitMillis - the maximum number of ms to wait until a graceful stop is achieved, before forcing a stop

Returns:

if successful ServerState#STOPPED

Throws:

SynapseException

getServerConfigurationInformation

public ServerConfigurationInformation getServerConfigurationInformation()

Returns the ServerConfigurationInformation, if the system is initialized and if not a Runtime exception of type SynapseException will be thrown

Returns:

the configuration information of the initialized system

getServerContextInformation

public ServerContextInformation getServerContextInformation()

Returns the ServerContextInformation, if the system is initialized and if not a Runtime Exception of type SynapseException will be thrown

Returns:

the context information of the initialized system

getClassLoader

public ClassLoader getClassLoader()

Returns the context class loader of the original thread.

Returns:

the context class loader of the original thread.

isInitialized

public boolean isInitialized()

Has server manager been initialized ?

Returns:

true if the server manager has been initialized by given required configuration information

getServerState

public ServerState getServerState()

Retrieves the state of the server.

Returns:

the state of the server
