All files are regenerated if changed.
That goes for the .java and the .class files that are created. The jsp server checks to see if the current version is the latest. If it is, nothing gets changed or recompiled. If things are different, programs are recompiled.
Youll notice that if you have a new jsp it always takes longer the first time. Or even when you change a jsp, the first time takes the longest for the page to come up in a browser. This is because of recompiling.
Does this make any sense?
