SAP J2EE Application / Portal Runtime
Application Interaction
Purpose
The PRT supports the use of SAP J2EE applications, libraries, interfaces and services in portal applications. It also supports the use of portal applications in SAP J2EE applications. Furthermore, it is also possible to execute a servlet as portal component.
This chapter describes these usages and the possibility to deploy portal applications as part of SAP J2EE Applications.
The term “SAP J2EE Application” refers here to any kind of SAP J2EE Application such as EJB and servlet. SAP J2EE libraries, interfaces and services are part of the SAP J2EE Engine, but not part of the J2EE standard.
On the portal side, a portal application can contain portal components and portal services. However it is only meant to use portal services in SAP J2EE Applications – portal components can not be used in SAP J2EE Applications. They can only be called and executed in the PRT environment.
The current implementation supports the following interaction scenario.
·
Executing a
Servlet as Portal Component
·
Accessing Portal
Applications From J2EE Applications
·
Accessing J2EE Applications from Portal
