    You can find most all the information you want on the SAP WEB AS servers http://www.sap.com">here as for how it differs from a WebSphere server or a Tomcat Server or BEA server well that is a huge topic. What exactly are you wanting to know?

    Basics:

    Check out http://help.sap.com/saphelp_nw04/helpdata/en/0d/a3bb3eff62847ae10000000a114084/content.htm

    for the top level information on the Web AS.

    As for details of the J2EE implementation, this comes directly from the official docs:

    Compliance with Java 2 Enterprise Edition

    The SAP J2EE Engine supports the industry standard Java 2 Platform Enterprise Edition and therefore has a broad base of security and development standards. On this base you can develop applications, which are transferable and independent of the manufacturer. The SAP J2EE Engine supports the following J2EE components and interfaces:

    Among all the features, java dictionary and the WebDynpro are the selling points of WAS. But if your implementation ever uses these two parts, then the solution is no longer portable to other application server.

    I am still not quite sure what's the difference between WebDynpro and JavaServer Faces, which is part of J2EE. It seems WebDynpro is just a simple web UI framework similar to Microsoft WebForm and the JavaServer Faces.
