Hi Rajeev,

Web Dynpro is SAP's strategy for developing Web applications, and is therefore the strategic approach for developing content for SAP's Enterprise Portal.

Web Dynpro applications can be integrated in the portal quickly and easily. A Web Dynpro application that runs in the portal can use the portal services that are available, without writing a single line of code. The applications running in the portal are called iViews. iViews communicate with one another using portal eventing - that is, they can send and receive events from other iViews on the same portal page, whether they are based on Web Dynpro or not.

If a company needs to use their own logos and colors (called themes), simply pressing a button can change the appearance of the application. Web Dynpro applications can be adjusted using the style sheet editor of the portal. For example, the colors in the tables are adjusted and automatically used in all applications. The integration of Web Dynpro applications in the portal will be intensified in future releases of the SAP NetWeaver application and integration platform.The application and integration platform of the SDN is SAP NetWeaver - based on the SAP Enterprise Portal, Knowledge Management, and J2EE Engine.

Hello Rajeev,

Web Continer is runtime environment for Web applications like servlets and jsps.it maintains and manges life cycle of servlelets and jsps.

when there is any request for webapplication(ex:http://<hostname>:50000/index.html),web container takes this http request and generates html content through servlets or jsp and retunrs it to client.

hope this helps.

Hello Rajeev,

J2EE Engine or J2EE stack is base for all java developments in SAP.if you want any java component in sap development,you require j2EE engine.it contains several componets like EJB container,WEB container,Web dynpro runtime ...etc for running different type of application.

Portla is addon to j2ee engine i.e portal runtine uses j2ee engine for executing it's application.so if you want to run your portal application,you require portal components which are installed on j2EE engine.

hope this helps
