You should review the WebAuction Web code at this time. You'll notice that many of the techniques used in this chapter have been implemented in the WebAuction application. Most notable and applicable are the form-based authentication functionality, and the use of the RDBMS and the caching realm. Every time a user logs into the site or registers, WebAuction uses form-based authentication. In order to process the form for registration, a JavaBean is used. The Java code in the JSP pages makes calls into the WebLogic Server realm.
