how to make "open resource" dialog in eclipse only find *.js files, not
*.jsp?

Is there any way in the Eclipse Open Resource (Ctrl+Shift+R) dialog, to
find *.js files, but NOT *.jsp or *.jspx or any other *.js* file? Someone
asked a related question, but the solution given just doesn't work in my
Eclipse Indigo.
