The Jolt Class Library provides four classes that implement the asynchronous notification mechanism for Jolt client applications:

• JoltSession—the JoltSession class includes an onReply() method for receiving notifications and notification messages.
• JoltReply—the JoltReply class gives the client application access to any messages received with an event or notification.
• JoltMessage—the JoltMessage class provides get() methods for obtaining information about the notification or event.
• JoltUserEvent—the JoltUserEvent class supports subscription to both unsolicited and event notification types.

For additional information about these classes refer to the Oracle Jolt API Reference.
