I get a similar error when I try to open the Web Dynpro perspective.

I have un-installed and re-installed NWDS. But no luck.

Any inputs on this?

Thanks in advance.

Hi,

Removing the .metadata folder and restarting NWDS fixed my NWDS as well. deleted the metadata folder and reimported the tracks and also did the J2ee engine settings again in preferences

Hope this helps!!

Please check in your plugin's if the activation plugin - com.sap.ide.eclipse.cbs.activation in activated ?

Which version of NWDS are you using?

Hello,

The issue was with the user rights for NWDS.

Somehow the privileges for my id went missing on the program files folder on my machine.

So on launching NWDS the plugins were not loaded.

Changed security properties and it worked fine.

Thanks.
