You should have a support contract with SAP - open a ticket for component BC-DWB-WD-JAV.

Unless you decompile the class files mentioned in the stack trace, the chances of stumbling into the solution for a NPE is pretty small.

I have just had a similar issue and have identified a fix.

In your install directoty for NWDI e.g. C:\Program Files\SAP\IDE\IDE70\eclipse

locate file VM.properties

The following settings worked with Win 2000, but not with Windows Vista:

-Xmx512m

-Xms128m

-XX:PermSize=32m

-XX:MaxPermSize=128m

By changing entries to following, NWDI worked with Vista:

-Xmx1024m

-Xms256m

-XX:PermSize=32m

-XX:MaxPermSize=128m

-Dos.name='Windows XP'

I hope this works for you.

Hi,

take a look into sap-plugin.log. There you can possibly find a more detailed message.

Best regards,
