ABAP and Java Stack: Which to choose/supported standards and components?

Hello,

I am trying to understand the role of the two stacks in NW. Maybe anyone has a few

hints where I can find answers to the following questions:

- An overview of supported Standards (Java 5 since when?)

- An overview of which component runs on which stack? Portal->Java, Integration Server->ABAP and so on.

- Guidelines when to install both stacks and when to use just one stack? When do I use which one?

- Has SAP an stategy towards an one Stack solution (possibly Java?)

Best regards and thanks for any pointers!

Stefan

    • An overview of supported Standards (Java 5 since when?)

    Go to service.sap.com/pam

    Product Availability Matrix will tell you about supported version and platforms.

    • An overview of which component runs on which stack? Portal->Java, Integration Server->ABAP and so on.

    Usually the question goes the other direction: what stacks we need for implementation of a particular function?

    More and more products require ABAP backend and Java frontend.

    For example Employee Self Service has been transerred from ABAP only ITS based to ABAP backend and Java frontend.

    Same with SRM.

    • Guidelines when to install both stacks and when to use just one stack? When do I use which one?

    Same as above, driven by business requirements, not technology.

    • Has SAP an stategy towards an one Stack solution (possibly Java?)

    No. Core business functions are still being developed on ABAP and interface, GUI etc utilize JAVA.
