- The demo application (Auction system) obviously consists of more than just some EJB's
- E.g. It has 3 different UI's that we haven't seen code for
- We're going to take a small look at the web-based UI
- The web-based UI makes use of other elements of the J2EE environment
- In particular, Java Server Pages (JSP)
- JSP is a server-side technology for dynamic generation of HTML
- JSP allows mixing of ordinary HTML with Java
- Ordinary HTML output as is
- Java executed and output substituted
- A JSP is compiled down to a servlet
- A servlet is another J2EE interface that allows Java code to easily handle an incoming request
- All HTML must be explicitly output
