Eclipse tips on source code

Try to attach source codes for *.jar, then the auto-generated source (such as method) will comes with meaningful name, for example, A generated execute(...) method of Struts Action:

without attach source:

    public ActionForward execute(
           ActionMapping arg0,
           ActionForm arg1,
           HttpServletRequest arg2,
           HttpServletResponse arg3
           throws Exception {
   }

lots of ugly arg0, arg1.... !!!

after attach Struts source codes to struts.jar:

    public ActionForward execute(
           ActionMapping mapping,
           ActionForm form,
           HttpServletRequest request,
           HttpServletResponse response)
           throws Exception {
   }

whew! much better !

Another tip is when you attach source codes, you can view java docs without assigning javadoc location. Eclipse will parse javadocs that inside attached source codes for you.
