    Hi Preethi,

    I need more Information about your scenario.

    Do you use the WAS only because of the jCo?

    If so then you can develop the application on client side, as a WAS is not necessary for jCo communication.

    Regards,

    Edgar

    hello preethi,

    you can write a servlet service to run on WAS that will

    invoke the BAPI from your backend server using JCO. from

    your client you can POST your data to that service using

    HTTP then.

    if you want to directly access the DB server rather than

    BAPI, you have to use java sql.

    good luck.

      hi folks,

      Write a simple Remote Enabled Function Module in the backend.

      This function module should have the logic to interact with the database. It could be as simple as just getting the data from the Front end using JCo and pushing it into the respective table and reteriving from the same (when the RFC is executed).

      In your Servlet, use JCo to connect to this R/3 System and Execute the Function Module giving the respective parameters. (Refer SAP JCo java docs for the usage of APIs). You can definitely achieve your business functionality with the APIs of JCo.

      Good Luck.

      Regards

      Ak.
