Creme 4.0 on MI 2.5 Sp13 ?

Hi forum,

I'm trying to upgrade my mobile applications developed with sap MI 2.5sp13 with Creme Virtual machine 3.27 (that support JDK 1.1.8);

I would like to know if it may be possible to use the MI Client on the PDA with a newer version of the creme runtime JRE because the supported jdk that i use now is too old.

<b>Is it possible to use the newer version of the creme (4.0) with MI 2.5 that supports jdk 1.3 or 1.4?</b>

MY TEST:

1. I modified my 'listOfJar.txt' with new jars of creme 4.0

2. I am trying to start MI

3. I always get the following error message (from JVM log <b>jscpout.log</b>)

    Hi Eliana

    MI is Personal Java compliant which means only JDK 1.1.8 is supported. MI on PDA will not support newer versions of JDK. Moreover Creme 4.0 is J2ME compliant where as MI is not J2ME compliant. Hence you can only use Creme 3.26, 3.27A etc.

    Hope this helps.

    Hi all

    But the Creme that is available in the link mentioned above will only be once that is certified by SAP and as of today Creme 4.0, 4.1 are never certified by SAP for MI. You may only be able to download Creme 3.2* versions.

    Best Regards

      Hi All,

      As I said, unfortunately we didn't have the choice to decide exactly what software platform to use in such dethails, we were obliged to follow strightly the project specifications obviously put together by people who have not all the necessary technical skills to preventivate all the possible situations such as this.

      The project is based on these specifications:

      - OFFLINE mode (clients are connected ONLY when in synchronizing mode, all the work within data must be managed locally on the device)

      - SAP MI 2.5 sp13 compliant

      - WAS 6.40

      - Satisfacting performances

      - Order capabilites.

      By saying this and after reading your answers I thing that the range of possibilities that is offered is a lot more restricted...

      Finally, talking about SortOrder, JDK 1.1.8 does not implement a satisfacting version of that...

      We talked and talked but if you would like to see or have an idea of what we created up now, please follow this links (sorry, for the italian language):

    hi Eliana,

    This is the Link to download the latest version of CrEme JVM. Here you go!

    http://www.nsicom.com/Default.aspx?tabid=289

    It will ask for your SAP Partner/Customer id. Once you give that, you are through!!!

    Good day.

    Regards

    Ak.
