Database web page wizard error

I'm trying to use the database web page wizard but it fails to have any
input fields. 
Part of the error log is as follows: 
!ENTRY org.eclipse.ui 4 4 Nov 09, 2004 21:37:35.427
!MESSAGE Unhandled exception caught in event loop.

I've reinstalled WSDC, but continue to have this problem. 
Any ideas?
