Good news! :)
Here's the usual story that explains the problem.
1. The developer creates and compiles a Bean or class with limited
functionality.
2. The developer creates a JSP page that uses the Bean.
3. Satisfied with no errors in step 2, the developer then finishes off the
Bean by putting in the functionality they want to call then recompiling the
Bean.
4. The developer modifies their JSP page to call the Bean's added
functionality then refreshes their JSP to find that the new functionality
isn't turning up.
The reason the new functionality doesn't turn up is that the JSP
server/container, while having the ability to detect changes to JSP's,
probably servlets, and maybe even includes, is not implemented to detect
changed support classes (like Beans) and reload them dynamically. By
restarting your server, you've forced the JSP server/container to reload
your support class.
