I really doubt that pursuing this will turn out to be a good use of
our time -- I fear that it is likely to introduce hard-to-find and fix
problems -- but if anyone wants to look into it....
-- a tomcat flag is unlikely to work in geronimo since we are not
using any tomcat class loaders.
-- I would investigate what tomcat does from this flag and if eclipse
has a similar feature and find out how they work.
-- I think I recall a jvm feature that lets you replace class
definitions in some circumstances. I've never used it and don't know
when it can be used.
Basically I don't see how you can reliably replace one class - say a
servlet class - in a web app without restarting the whole web app.
There is going to be at least one instance of the servlet class
created, so you need to stop and recreate the servlet. Assuming it
has load-on-startup == 0..... you have to start the whole web app.
If people have different perspectives I'd like to hear them :-)
From a user perspective what I do is to set up a maven build that
builds my app, uses the car-maven-plugin to build it into a geronimo
plugin, use the car-maven-plugin again to build a micro server
including my app, and use selenium to run tests against it in the
micro server.

I also agree that it's nice to have that. But I guess it's not as
easy as just exposing the attribute. As David J. pointed out in
another thread, we are dealing with two containers here. I did a
small experiment by adding a context.xml in Tomcat's conf folder,
and set "reloadable=true". Then Tomcat reports a
NullPointerException each time it wants to do class reload. We need
to look deeper into this.

Currently, it seems that the reload attribute of the context is not
exported by the TomcatWebAppContext GBean, shall we add this
attribute to allow the user to set it in the config.xml ?
Thanks !

Hello,
My name is Kai, a new geronimo user. I met a small problem when
develope a web application on geronimo. It seems that geronimo won't
reload the java class file when it is replaced.
Here is what I did:
After I deploied a war file, I wanted to change a java class, so I
replaced the old one with a new one, but the application didn't make
any changes. Then I restart the war application, it works.
Is there any way to make geronimo reload the java class file
automaticly?
I expect that there could be a config file which can enable this
function, but I didn't find...
Would anyone help?
