Reloading - again..

[Endre Stølsvik <En...@Stolsvik.com>]

Sorry for going on and on with this, but I cannot stop being puzzled by
it.

It seems like Tomcat only really reloads the one class that you hit
first. I do a full recompile (deleting all class files just to be sure!),
and look at the tomcat log while clicking reload.

These logs are both right after a full recompile, but hitting different
servlets first:

Here I hit "Initialize" first, and then "design.Topbar" and then
"Workbench".

This is strange right away, because why aren't all the servlets destroyed
right away? I mean, they're all ditched right away, since a context reload
actually puts the whole ClassLoader out of scope and makes a new one to be
able to reload the classes. So why aren't they all destroyed too?


Then this is if I hit Workbench first, and then hit the "design.Topbar".

Why is this so?

One more thing: Shouldn't the "load-on-startup" servlets also be started
up again on a context-reload?

btw; I'm using tomcat 3.2 final.
