Method Detail

start

public Object start(ServiceBeanContext context)
             throws Exception

The start method provides the capability for a ServiceBean to initialize itself and make it ready to accept inbound communications, returning an Object which can be used to communicate with the ServiceBean. It is the responsibility of the ServiceBean to initiate appropriate startup logic. If the ServiceBean has started itself, subsequent invocations of this method will not re-start the ServiceBean, but return the Object created during the initial start

Specified by:

start in interface ServiceBean

Parameters:

context - The ServiceBeanContext containing ServiceBean initialization attributes

Returns:

An Object that can be used to communicate to the ServiceBean

Throws:

Exception - If any errors or unexpected conditions occur

initialize

public void initialize(ServiceBeanContext context)
                throws Exception

The initialize method is invoked to initialize the ServiceBean. This method is invoked only once. The ServiceBeanAdapter initializes required infrastructure elements in order to prepare the ServiceBean for processing.

Specified by:

initialize in interface ServiceBean

Parameters:

context - The ServiceBeanContext to initialize the ServiceBean with

Throws:

Exception - If something unexpected happens

                throws Exception

The initialize method is invoked to initialize the ServiceBean. This method is invoked only once. The ServiceBeanAdapter initializes required infrastructure elements in order to prepare the ServiceBean for processing.

Parameters:

context - The ServiceBeanContext to initialize the ServiceBean. If this parameter is null a NullPointerException is thrown

protected Remote getExportedProxy()

Get the Object created by the configured Exporter

Returns:

Returns:

The proxy to use

getServiceProxy

public Object getServiceProxy()

Deprecated. Use ServiceBeanContext.getDiscoveryManager

Get the DiscoveryManagement instance for this service. If the DiscoveryManagement attribute is null, this method will create a DiscoveryManager instance. If the DiscoveryManagement attribute is not null, this method will return the DiscoveryManagement instance that has already been created

Returns:

A DiscoveryManagement instance created from the ServiceBeanContext

Throws:

IOException - because construction of the class DiscoveryManagement implementation may initiate the discovery process, which can throw an IOException when socket allocation occurs.

Returns:

The EventHandler that has been created to handle the sending of SLAThresholdEvent events

Specified by:

unadvertise in interface ServiceBean

Specified by:

unadvertise in interface ServiceBeanAdapterMBean

See Also:

Parameters:

force - If true, unexports the ServiceBean even if there are pending or in-progress calls; if false, only unexports the ServiceBean if there are no pending or in-progress calls. If the force parameters is false, unexporting the ServiceBean will be governed by the following configuration properties:
