Don't use sendError.
- Call response.setStatus(int).
- Calculate the size of your body text
- Call setContentLength(value from previous step)

There is no need to turn jspf into classes. The jspf are included by real jsp

A lot of custom coding on your own.
You'd need a filter which traps all your precompiled servlet mappings and
then checks to see of the jsp the file was mapped to has changed. Then you'd
need to somehow manage compiling the JSP and loading the class file while
ignoring the existing mapping. In
From the jasper task all the [valid] jsp's are turned into java files and
compiled into class files. Those class files need to be a jar file in
WEB-INF/lib or inside WEB-INF/classes. The jasper task can also rewrite
web.xml so that all the mappings from the JSP --> class file are taken care of.
So, how can I do it with tomcat not "out of the box"?

Solely my opinion based on experience with 100's of servlets- it doesn't
matter. If the application is complex enough to worry about this, get a
MVC framework like struts for better organization inside the servlet and
let it draw the distinctions between pieces of the application.
