    Hello Arthur,

    If you have NWDS 7.3x it means you have a Portal (or other AS Java) 7.3 or 7.4, exactly as you wrote. But with these releases you have to stick with lower JDK, that is 1.6. Only NetWeaver AS Java 7.5 support Java 8.

    Best Regards,

    Peter

    Hello Arthur,

    Here you can find more information about the Compatibility between the SAP JVM (JDK) and the NetWeaver release:
    https://wiki.scn.sap.com/wiki/display/ASJAVA/SAP+JVM+Netweaver+compatibility+and+Installation

    As Peter mentioned NetWeaver 7.5 supports Java 8.

    Best Regards,

    • Arthur, your question has been answered. The JVM version is the J2EE version for all intents and purposes. If you are using NetWeaver 7.5, then it is running on SAPJVM 8 (or 8.1), and that is what you must develop with. That is the equivalent of JDK 1.8 (or J2EE 8) outside of SAP.

      Cheers,
      Matt

    Hello Arthur,

    Please refer to Peter's answer (and review the other answers and comments as well)

    The 7.50 release of AS JAVA (a.k.a J2EE Engine) runs with SAPVM 8 (this acts like a JRE) on server side, and expects NWDS 7.5 on client side that uses a 1.8 JDK (usually again SAPVM8 recommended that includes the SDK part).

    In this context 1.7 cannot be used.

    730/740 J2EE Engine runs with SAPVM6 and expects NWDS 730/731 that expects JDK1.6.

    I am not sure there is a J2EE Engine of any Netweaver AS JAVA releases that would use a JVM7.

    There is no version of NWDS you could run with a JDK1.7.

    I am not sure either tricking with with 1.7 compile mode would be a way out here.

    Best Regards

    Ervin

    Okay, I have now installed a Portal 7.5 AS Java.

    Where can I find the Information which J2EE Version I can Use?

    I would like to use J2EE 7.

    Is it possible?

    How?

    Best Regards,

    Arthur
