Should I use a "non-Javadoc" comment?

I implemented my own method defined in an interface. However when I try to add Javadoc to this method Eclipse gave me a comment like this:

/* (non-Javadoc)
 * @see javax.servlet.ServletContextListener#contextInitialized(javax.servlet.ServletContextEvent)
 */

Actually, I really need to add some comment to this method. What should I do?
