   Using BEA Jolt

A Jolt client applet or application that is built using JoltBeans typically consists of Jolt-aware GUI beans, such as JoltTextField or JoltList, and JoltBeans, such as JoltServiceBean and JoltSessionBean. The main mode of communication between Beans is by JavaBeans events.

Jolt-aware beans are sources of JoltInputEvents or listeners of JoltOutputEvents or both. JoltServiceBeans are sources of JoltOutputEvents and listeners of JoltInputEvents.

The Jolt-aware GUI Beans expose properties and methods so you can link the beans directly to the parameters of a BEA Tuxedo service (represented by a JoltServiceBean). Jolt-aware beans notify the JoltServiceBean via a JoltInputEvent when their content changes. The JoltServiceBean sends a JoltOutputEvent to all registered Jolt-aware beans when the reply data is available after the service call. The Jolt-aware GUI Beans contain logic that updates their contents with the corresponding output parameter of the service.

The following figure represents the possible relationships among the JoltBeans.
