reload a class file without restarting Tomcat

[Michel Getraide]

Hi,
I have a webapp (java, jsp, struts,mysql) on a shared host.
Tomcat version is 5.0.27.
I have my webapp locally. When i do a slight change in a java file, I would
like to be able to upload the updated recompiled class file in my webapp on
the shared host.
Is there a way that the class be reloaded without restarting the server (the
server restarts once a day only since it is a shared host.)
Thanks a lot,
Michel
