    • Hi Amit,

      I will assume that you will be going with 6.40 SAP Web AS. With this release there is quite a bit of technical funcationality that is only available on the J2EE side of things...for instance Web Dynpro. If you want to use this functionality you will need to know some java. That said, you can use BSP pages that are based on ABAP to do web development if you like. There is also support for creating and calling web services from ABAP. But in the future, more and more will be coming out on the J2EE side of things from SAP, and you will need to support this...so obviously if your ABAPers can start to learn Java/J2EE now, it will only make things easier for your company going into the future.

      I hope this helps!

      Cheers,

      Jeff

    First of all, I'm a Java developer who has within the last 18 months gotten into SAP and ABAP development.

    Questions:

    1. Will the IDE's ever merge (ie will SE80 and NetWeaver Developer Studio (Eclipse)) ever come together?

    2. Compare and contrast transactions in J2EE with the ABAP classical transactions and object-oriented transactions.

    3. Are there any published performance metrics comparing the SAP J2EE server to others (IBM, Oracle, BEA etc).

    4. Is the WebDynpro idea supposed to be the notion that we create a model for our application then implement that model (more or less automatically) in the language of our choice (Java, ABAP, C#)?

    5. What will OpenSQL look like in the Java context? How does it differ from SQJ?

    6. Will SAP J2EE developers ever have direct access to the R/3 data dictionary? Or will we have to used BAPIs/RFMs forever?

    Thanks for your time

      Hi Jeff,

      Thanks for the nice presentation. I have also gone through the recorded session at AT&T but it will be helpful if we can get the link to download the presentation. Is the presentation available for download?

      Regards

    Hi All,

    If you need a short tutorial to bring you up to speed on Java (with JCo!) for ABAP programmers. Have a look at www.sapgenie.com

    It's very easy to read, and it will give you <b>a good grounding for J2EE</b>if you don't have any Java experience.

    BTW I delivered the <b>FIRST</b> course of J2EE for ABAP programmers at SAP Education centre in Brussels.

    Thank you for the webinar on Wednesday, it was very informative. I have a few follow-up questions:

    1. Are there any specific release dates yet for Web AS 6.40? With the Developer Studio and the integrated ITS, it seems worth waiting for when planning an upgrade.

    2. I had read that Web Dynpro for ABAP was to be included in 6.40, did you say that it would not be until a later release?

    3. With NetWeaver '05, will there be a new release of the Web AS - 6.50? Any new development capabilities planned with the next release?

    4. What is the SAP Integration Framework that is shown sitting on top of the Eclipse Plugin Framework?

    5. As far as data access, and ABAP schema and JAVA schema, is it correct to say that any data access for SAP data as we know it today will be through BAPIs, RFC, connectors, etc. With my limited knowledge of JAVA, I assume it is possible for a JAVA application to access SAP data with a BAPI while also accessing external data through SQL calls?

    Thanks,

    • Hi Jeff,

      good questions, below are your answers:

      1) 6.40 Web AS will be released for Rampup at the end of March. For more information about rampup visit: http://service.sap.com/rampup

      2) Yes, Web Dynpro for ABAP was originally planned for release with 6.40 Web AS, it has now been moved back to the NetWeaver 05 release of the Web AS.

      3) Yes, there will be a new release for NetWeaver 05.

      4) The Integration framework is refering to the ability to easily create and to call web services.

      5) Yes, all data access from Java to ABAP will be made using BAPIs/RFMs, IDocs, and web services...the SAP Java Connector plays a critical part in this. As for calling the underlying ABAP database schema from Java, this is not supported! There are many reasons for this, one being that the data integrity is maintained at the ABAP application level, not in the database.

      I hope this helps!

      Cheers,

      Jeff
