Apache Web Server

Hi,
We are using Apache Web Server under Unix.
We have a problem related to reloading of jsp files.
When jsp file is first time put into webserver
and accessed through the browser .java and .class files are created.
When we change the jsp file and access it again the file is not getting
reloaded with the changes. But we get the same old jsp file.
We tried after clearing the history files at browser level.
We tried after deleting the .java and .class files still we are not
able to get the new jsp file. Even when we delete the .java and .class
files, still we get the old jsp file.
We tried to set the property "autoreload= true" in "zone.properties" file
which is used during server startup, but not able to reload the new jsp
file.
We are able to get the new(changed) jsp files only if we restart the
web server. But we dont want to shutdown and restart the web server
everytime we make changes to jsp file. Can somebody help us with this???
