                                           Properties properties,
                                           DataResourceAccessor dataResource)
                                    throws SessionManagerCreationException

Creates a new session manager instance.

This method is invoked only once when a data service resource is instantiated. The object returned is then used for managing all the sessions associated with that data service resource.

Parameters:

configuration - The sessionConfiguration element from the session configuration file. This may contain settings used to initialise the SessionManager.

properties - The properties associated with the session.

dataResource - The data resource accessor associated with the session manager or null if no data resource accessor is associated.

Returns:

a new SessionManager, initialised and ready for use.

Throws:

java.lang.IllegalArgumentException - if configuration is null

SessionManagerCreationException - if there is a problem creating the new session manager. The consequence of this is that the data service resource cannot be properly initialised, so requests cannot be processed.
