changing class file and reloading question

Hi,

I'm running tomcat 4.1.27 standalone on Redhat 9

I have a class that I'm changing (development) and don't want to have to
restart tomcat each time I make a change.

It wouldn't be so bad to do that if it wasn't for the fact that
tomcat takes ages to read my servlet every time it's restarted.

I have got the following entry in my server.xml file

#####################################
<DefaultContext reloadable="true"/>

        <!-- Tomcat Root Context -->

        <Context path="" docBase="ROOT" debug="0" reloadable="true">
        </Context>
#####################################

The class I'm changing is in the ROOT/WEB-INF/classes directory

the console message when I hit 'reload' on the browser is:

WebappClassLoader:   Resource '/WEB-INF/classes/Topic3x4.class' was
modified; Date is now: Wed Aug 20 05:53:59 CST 2003 Was: Wed Aug 20
05:44:04 CST 2003

How do I get tomcat to indeed reload the classes without having to
restart each time?

Thanks,
kind regards,

You can reload using the manager app (the link is on the start page when 
you first start tomcat).  You can also use an ant target.  You can 
reload a single webapp, which is probably the better way of doing it.  
Here's an example target from a build.xml that takes an arguement:



  <target name="reload" depends="deploy" description="Reloads Tomcat 
Application (Local)">
    <get src="http://127.0.0.1:8080/manager/reload?path=/${app.name}"
    dest="status.txt"
    username="yourtomcataccount"
    password="yourtomcatpassword" />
    <loadfile property="catalina.reload" srcFile="status.txt" />
    <echo>${catalina.reload}</echo>
    <delete file="status.txt"/>
  </target>
