A function inside a JSP
This is something that I recently found out the hard way. In JSP, never, ever use global variables using a <%! ... >. When the servlet is generated, the global variables are placed outside the service() method.
Why did I do this in spite of dire warnings? I needed to call a function inside a JSP. The simple solution: Don't. Put the method inside a bean and call it there. MVC, remember!?
