   Using BEA Jolt

BEA Jolt is a Java class library and API that provides an interface to BEA Tuxedo and BEAWebLogic Enterprise (WLE) from remote Java clients.

BEA Jolt consists of several components for creating Java-based client programs that access BEA Tuxedo services. These Jolt components are as follows:

• Jolt Servers-One or more Jolt servers listen for network connections from clients, translate Jolt messages, multiplex multiple clients into a single process, and submit and retrieve requests to and from BEA Tuxedo-based applications running on one or more BEA Tuxedo servers.

• Jolt Class Library-The Jolt class library is a Java package containing the class files that implement the Jolt API. These classes enable Java applications and applets to invoke BEA Tuxedo services. The Jolt class library includes functionality to set, retrieve, manage, and invoke communication attributes, notifications, network connections, transactions, and services.

• JoltBeans-BEA JoltBeans provides a JavaBeans-compliant interface to BEA Jolt. JoltBeans are Beans components that you can use in JavaBeans-enabled integrated development environments (IDEs) to construct BEA Jolt clients. Jolt Beans consists of two sets of Java Beans: JoltBeans toolkit (a JavaBeans-compliant interface to BEA Jolt that includes the JoltServiceBean, JoltSessionBean, and JoltUserEventBean) and Jolt GUI beans, which consist of Jolt-aware Abstract Window Toolkit (AWT) and Swing-based beans.

• Jolt Repository-A central repository contains definitions of BEA Tuxedo services. These repository definitions are used by Jolt at run time to access BEA Tuxedo services. You can export services to a Jolt client application or unexport services by hiding the definitions from the Jolt client. Using the Repository Editor, you can test new and existing BEA Tuxedo services independently of the client applications.

• Jolt Internet Relay-The Jolt Internet Relay is a component that routes messages from a Jolt client to a Jolt Server Listener (JSL) or Jolt Server Handler (JSH). This component eliminates the need for the JSH and BEA Tuxedo to run on the same machine as the Web server. The Jolt Internet Relay consists of the Jolt Relay (JRLY) and the Jolt Relay Adapter (JRAD).
