An application client module is a JAR (Java ARchive) file containing a client for accessing a Java application.
The J2EE (Java TM 2 Platform for WebSphere Application Server Enterprise) Application Client and the Java Application Thin Client are supported by this product. Both clients provide first-tier client support where Web applications are enabled with Java technologies.
The Java Application Thin Client provides a lightweight, downloadable Java application run time that is capable of interacting with enterprise beans. This client is designed to support those users who want a Java client application programming environment without the overhead of the J2EE platform on the client machine.
