linkageError

Hi,

I am using Jigsaw to run servlets but I´ve got an linkageError by trying to define one alias for a Servlet.
When I try to click on the servlet icon, I don´t get anything.
I think I have badly define my alias for the servlet. So I have an identifier without class related to it ...
How could I get rid of this identifier which points on nothing ?

Any help on this would be much appreciated.
Thank you.
