There are many ways to do this using the scope attributes Milt notes below (though "context" scope is called "application" scope in the JSP spec) using scriptlets (not recommended) and tags (JSTL, Struts, and custom). See jakarta.apache.org/struts to educate yourself.
BTW: I have all the main books. I like Jason's best because it is the most sophisticated. Marty's books are very good for beginners or quick reference for the experienced. And then there's David Geary's "Advanced JavaServer Pages" (Sun/Prentice Hall 2001), which does an excellent job with custom tags, MVC/Model 2 design, database access, XML, and security. For an in-depth examination of JSP tags, Gal Schachor's, et al, "JSP Tag Libraries" (Manning, 2001) even goes into Java reflection. If you just need an excellent overview of JSP, Servlet and J2EE technologies and how they can interoperate, get a copy of Jim Farley's, et al, "Java Enterprise In A Nutshell, 2d ed." (O'Reilly 2002, which, btw, is coauthored by William Crawford, Jason's collaborator on his 1st edition).

Sounds like request is what you want. Check the spec/API for details. (The relevant methods are setAttribute/getAttribute.)
