All Implemented Interfaces:

FactoryCallback, GridServiceBase, GridServiceCallback, ServiceDataValueCallback, ServiceProperties

public abstract class EJBHomeFactoryProvider

extends GridServiceImpl

implements FactoryCallback

This is the base class of EJB Home Services. They expose any method on the home interface that returns a single instance of the remote interface. (all of the create and find methods that don't return enumerations)

Constructor Detail

EJBHomeFactoryProvider

public EJBHomeFactoryProvider(java.lang.String name,
                              EJBHome _home,
                              EJBObject ignoredParam)

Method Detail

preCreate

public void preCreate(GridServiceBase base)
               throws GridServiceException

Description copied from interface: GridServiceCallback

Called when a service object is created.

Specified by:

preCreate in interface GridServiceCallback

Overrides:

preCreate in class GridServiceImpl

Throws:

GridServiceException

initialize

public void initialize(GridServiceBase base)
                throws GridServiceException

Description copied from interface: FactoryCallback

associates this object with its GridServiceBase service. This method is called when the first instance creation is requested.

Specified by:

initialize in interface FactoryCallback

Parameters:

base - factory service that this factory callback should create services for

Throws:

GridServiceException - if the callback object could not be initialized

createRemoteService

public java.lang.String createRemoteService(EJBServiceImpl skel,
                                            java.lang.String nameClue)
                                     throws java.rmi.RemoteException

This method sets the skeleton that will be returned by createServiceObject(). Since it is a regular instance variable this method must be synchronized.

Throws:

java.rmi.RemoteException

createServiceObject

public GridServiceBase createServiceObject(ExtensibilityType creation,
                                           ExtensibilityTypeHolder extensibilityOutput)
                                    throws GridServiceException

Description copied from interface: FactoryCallback

creates a new Grid service instance that implements the GridServiceBase interface

Specified by:

createServiceObject in interface FactoryCallback

Parameters:

creation - parameters the client may pass to the factory at creation time

Throws:

GridServiceException - if the service instance could not be created

getCreationType

protected ExtensibilityType getCreationType(EJBObject remote,
                                            java.lang.String nameClue)

This attempts to guess a good name for the "path" portion of the service's url
