Since servlets know nothing of GUI, they do not offer any way to manage GUI behavior.
JavaScript knows nothing of Java. They are two entirely different things. The only way
they can communicate is via request parameters. So, if your customer requires that a
particular thing happens when a certain value is selected from a drop-down list, you
have to pass some value to the servlet in a request parameter. You can also use
JSP/servlets to conditionally insert JavaScript into your HTML output. The book Web
Development with Java Server Pages (Fields and Kolb, published by Manning) discusses
this a little bit, but not to any great extent.

I think the subject of effective gui in a browser is pretty big and pretty
distinct from server-side techniques, whether done in servlets or something
else. I think you may have to concentrate on the gui area without
consideration of the server-side, and then work out the links to the
back-end (via JSP, etc.). A good book on JSP should give some hints, but I
have none to recommend.
