  com.ibm.di.systemqueue.driver.WebsphereESB

All Implemented Interfaces:

JMSDriver

public class WebsphereESB
extends Object
implements JMSDriver

The JMS Client implementation for Enterprise Servcie Bus. It initialize the JMS client and provides specific way for obtaining JMS ConnectionFactory. JMS Client is limited for only one ConnectionFactory for Queue/Topic at a JVM.

Method Detail

getQueueFactory

public javax.jms.QueueConnectionFactory getQueueFactory()
                                                 throws Exception

This method retrieves the provider-specific javax.jms.QueueConnectionFactory object

Specified by:

getQueueFactory in interface JMSDriver

Returns:

QueueConnectionFactory object of the JMS Driver

Throws:

Exception - if QueueConnectionFactory cannot be created

getTopicFactory

public javax.jms.TopicConnectionFactory getTopicFactory()
                                                 throws Exception

This method retrieves the provider-specific javax.jms.TopicConnectionFactory object

Specified by:

getTopicFactory in interface JMSDriver

Returns:

TopicConnectionFactory object of the JMS Driver

Throws:

Exception - if TopicConnectionFactory cannot be created

initialize

public void initialize(Hashtable env)
                throws Exception

The initialize(Hastable env) method is passed a java.util.Hashtable object which stores provider-specific parameters, which can be used for connecting to a specific instance of the JMS server. Normally this method would use the supplied parameters to connect to the JMS server and obtain a javax.jms.TopicConnectionFactory object and/or a javax.jms.QueueConnectionFactory object. Then the method would store the object(s) in member variables so that it/they can be later retrieved via the getQueueFactory() and/or the getTopicFactory() method.

Specified by:

initialize in interface JMSDriver

Parameters:

env - Hashtable that holds Driver properties

Throws:

Exception - if JMS Driver cannot be initialized

terminate

public void terminate()
               throws Exception

This is a call-back method used to notify the JMS Driver so it could clean any used resources. This method should be used in very rare cases.

Specified by:

terminate in interface JMSDriver

Throws:

Exception - if error while terminating occurs.
