NWDS cannot find Java Virtual Machine

Posted on Jan 08, 2007 at 03:39 PM 770 Views

I just installed Developer Workspace (SAP NetWeaver 2004s SR2 (SP9)

) in my another laptop.

When I try to launch NWDS, I got the following message:

A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to run Eclipse. No Java Virtual Machine was found after searching the following locations:

3\bin\javaw.exe

But I have jdk 1.4.09 in my C;\ and set the environment variable:

In sytem variable, I set:

JAVAHOME = C:\j2sdk1.4.2_09

and Path: C:\j2sdk1.4.2_09\bin

The problem not solved with these config.

Thanks for advise.

    Hi Keant

    Richt click on Studio icon and go to Shortcuts and check whether the target is set to <b>"C:\Program Files\SAP\IDE\IDE70\eclipse\SapIde.exe" -vm "C:\j2sdk1.4.2_09\bin\javaw.exe"</b> or not. If that is correct then it works fine.

    Regards,

      Jhansi,

      Doing this actually solve our problem:

      Richt click on Studio icon and go to Shortcuts and check whether the target is set to "C:\Program Files\SAP\IDE\IDE70\eclipse\SapIde.exe" -vm "C:\j2sdk1.4.2_09\bin\javaw.exe"

      Thanks.

    Hi Kent,

    i would suggest you re-install your JDK.

    Maybe it is a typo, but the environment variable is JAVA_HOME and not JAVAHOME.

    If you are sure your JDK is installed correct, you can also try to start the Developer Studio from the installation path with this command:

    <b>Example</b>

    SapIde.exe -vm c:j2sdk1.4.2_09binjavaw.exe

    Regards,

    Martin

      Hi,

      add the following line as part of your short cut.

      -vm "C:\jdk1.5.0_07\bin\javaw.exe"

      Ex:"C:\Program Files\SAP\IDE\IDE71\eclipse\SapNetweaverDeveloperStudio.exe" -vm "C:\jdk1.5.0_07\bin\javaw.exe"

      Inside SapNetweaverDeveloperStudio.ini check for the entry

      -DJDK.1.5.0_HOME=C:\jdk1.5.0_07

      Modify the contents according to your system.

      Regards

    Hi Kent,

    After installing the JDK set the sytem variable <b>JAVA_HOME to C:\j2sdk1.4.2_09.</b> As u have j2sdk1.4.2_09 there no problem with the version compatibility also.While installing the NWDS make sure that it is taking the java path that u have set already.

    If u have already installed then try to check the path of jdk that NWDS has taken.

    Regards,

    Jhansi
