Servlet configuration in Tomcat 4.1

I am using Tomcat 4.1.29 on fedora. JSP is working fine but there is problem in configuring servlet. In web.xml
I have uncommented
<!-- The mapping for the invoker servlet -->
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>

In server.xml added the virtual host.
In httpd.conf added

CustomLog domlogs/allhopeindia.com combined
ScriptAlias /cgi-bin/ /home/allhope/public_html/cgi-bin/

<IfModule mod_jk.c>
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
JkMount /servlets/* ajp13
<Location "/examples/WEB-INF/">
AllowOverride None
deny from all
</Location>
</IfModule>

I created WEB-INF folder and inside web-inf Classes. Uploaded the class files in it. Now when I go to
http://domain.com/servlet/CLassFileName it don't work.

Do I have to make any changes in workers2.properties.

Please suggest me where I am going wrong.
Thanks.
