The Portal on SAP Web Application Server 

The portal is deployed on the J2EE Engine, which is a component of the SAP Web Application server based on the Java 2 Enterprise Edition (J2EEÔ) standards. The Portal Platform relies on the J2EE architecture implemented by the application server.

For detailed information about the J2EE architecture, refer to Java architecture in SAP Web Application Server.

The portal is comprised of software that provides core functionalities, such as applications that are loaded at runtime, before other applications. Such applications provide central functionality to the Portal Platform, such as integration with the User Management Engine and the Portal Content Directory.

In addition to the runtime libraries, configuration files, core applications and so on, the portal sets up other services that interface with the J2EE Engine such as, PRTBridge: a service containing functionalities and services for inter-cluster communication. This facilitates the integration processes between the runtime environment of the portal and J2EE Engine. 

The following provide the interfaces between the portal and SAP Web Application Server:

·        Portal Runtime Container

A container implemented for the runtime processes of the portal to manage:

¡        The deployment of Portal Applications: these consist of Java software that is programmed for the portal.

¡        The communication between Portal Applications and the J2EE application.

¡        The robust interaction and integration between Portal Applications and the J2EE Engine.

·        PRTBridge Service

The PRTBridge is the link between the runtime process of the portal and the J2EE Engine cluster configuration. It is installed for the portal as a J2EE Engine service.

The PRTBridge allows communication among J2EE Engine cluster elements, including communication with the J2EE cluster groups. For example, the number of cluster servers, the name of each server, and so on.
