The Java API for ENS uses a subset of the standard JMS API, with the addition of two new proprietary methods:
com.iplanet.ens.jms.EnsTopicConnFactory
com.iplanet.ens.jms.EnsTopic
The following list of JMS object classes is used in the Java API for ENS:
javax.jms.TopicSubscriber
javax.jms.TopicSession
javax.jms.TopicPublisher
javax.jms.TopicConnection
javax.jms.TextMessage
javax.jms.Session
javax.jms.MessageProducer
javax.jms.MessageConsumer
javax.jms.Message
javax.jms.ConnectionMetaData
javax.jms.Connection
The Java API for ENS does not implement all the JMS object classes. When customizing, use only the object classes found on this list.
