Hi,
Your JDK version is not compatible with the nwds version so better try to install the JDK 1.4.* and then set JAVA_HOME path.
Close the NWDS and restart the NWDS with using the new workspace.
Hope it will resolve ur problem
Thanks

Hi,

hi,
1. For nwds 7.0 you should use jdk 1.4.8 and
2. Install jdk 1.4.8 and nwds again but before installing it delete your workspace .
Now try to create your maodel it should work now.
Thanks and regards.

Hi Rami,
JDK 6 is not compatible with the NWDS 7.0.14 version. You need to work with some higher version of jdk 1.4 (say 1.4.2_12 or so)
Now, after installing the compatible jdk version, verify the environment variable JAVA_HOME is set to it, start NWDS in a fresh new workspace (I would advise you to remove jdk 6 if you do not need it for any other purpose).
Kind Regards,
Nitin

Hi Rami,
It looks like this NPE is coming from the Web Dynpro model plug-in code.
If 'Create Model' was working earlier, then this might be due to metadata corruption. Close the NWDS.
1) Either delete the contents of the metadata folder of your workspace & restart NWDS.
2) Or you can restart NWDS in a fresh workspace.
Please verify that you are providing all the required parameters in the model creation wizard.
If the NWDS installation has gone fine & still the problem persists, this seems to be a bug & you can raise a customer ticket (CSS message on Web Dynpro component)
Kind Regards,
Nitin
PS: If you are using quite old version of NWDS, I would advise you to upgrade to a later version as these very basic things should be working fine.

Which version of NWDS are you using? Have you installed all the plugins?
