Edge application customization
To implement the Application Service at the Edge feature, a Java™ 2 Enterprise Edition (J2EE) application must be repackaged to differentiate between parts that can execute on an application server located at the Caching Proxy and parts that must execute on an origin application server. This change can be done to a finished application, but it also can be partially automated by implementing certain Java interfaces when the application is written.
Adapting applications for Application Service at the Edge describes the interfaces provided for creating edge applications and discusses guidelines for determining which components of an application should be executed at an Application Server.
