The J2EE application client programming model provides the benefits of the J2EE platform for the Java client application. Use the J2EE application client to develop, assemble, deploy, and launch a client application. The tooling provided with the WebSphere platform supports the seamless integration of these stages to help the developer create a client application from start to finish.
The Application Client for WebSphere Application Server V6 (Application Client) consists of the following client applications:

• J2EE application client application (uses services provided by the J2EE Client Container)
• Thin application client application (does not use services provided by the J2EE Client Container)
• Pluggable application client
• Applet application client application
• ActiveX to EJB Bridge application client application
