Method Detail

initialize

public void initialize(Hashtable aEnv)
                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:

aEnv - Hashtable that holds Driver properties

Throws:

Exception - if JMS Driver cannot be initialized
