Tomcat servlet class not refreshing

Question

I just started to work with Tomcat.
My problem is that once I have compiled and put a servlet in myApps\WEB-INF\Classes directory even after I recompile it the browser displays old version. Only stopping and starting Tomcat shows the new version
My browser is IE v 6.
I have done everything as instructed in the book Java for the Web with Servlets... by Kurniawan.
My web.xml looks like so
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
<servlet>
          <servlet-name>Testing</servlet-name>
          <servlet-class>TestingServlet</servlet-class>
</servlet>
</web-app>      
My CLASSPATH variable looks like so
c:\j2sdk1.4.2_01\lib;.;c:\1ourfolder\Java Stuff;c:\jakarta-tomcat-4.1.27\common\lib\servlet.jar;C:\IBM\SQLLIB\java\db2java.zip;C:\IBM\SQLLIB\java\db2jcc.jar;C:\IBM\SQLLIB\java\sqlj.zip;C:\IBM\SQLLIB\bin;C:\IBM\SQLLIB\java\common.jar
Is there something I need to add in the web.xml file? On the comp.lang.java.help forum there was reference to the WEB-INF\classes directory being in classpath and removing that made it work but I don't have that situation AFAIK.
Thanks

This must have been answered many times but with the software evolving as it does there must be different ways of doing this. This is what I did
On your browser go to the manager page.
http://localhost:8080/manager/html
You may be prompted for a userid and password
If you haven't done so already edit the conf\tomcat-users.xml file in the tomcat directory and add a line to set you up as a manager. This is going to be something like this
<user username="manager" password="tomcat" roles="manager"/>
Login as manager/tomcat.
On the resultant webpage you should see a list of applications, myApps will be in that list. Stop it and start it (follow the grid to the right)
Now your servlet class will be refreshed.
I looked at other responses in this forum and found this answer
http://forum.java.sun.com/thread.jsp?forum=33&thread=404559
"...If it is tomcat 4.1 then you can use its adminitrator jsp page to make your context(webapp) reloadable. This in turn will make chages to your your server file and will add the context back to tomcat without stopping it..."
At this time I haven't figured out how to do this ;-)
Oh, and could you use code tags the next time?
