The portal components for the SAP EP are enterprise applications built on the J2EE platform. SAP's Portal Component API includes a custom framework called DynPage, which supports J2EE application development for the EP. DynPage provides a collection of interfaces and abstract classes to structure the application architecture of portal components that require dynamic page processing. Essentially an implementation of the Service to Worker pattern, the DynPage framework organizes the Controller and Dispatcher classes and subsequently manages their interaction with JavaBeans and JavaServer Pages
