Servlet not found error

Question

Hi everyone,
i am trying to write a chat application using applet,servlet and RMI.
so i have my servlet and aaplets accordingly...
but when i put my servlet and applets in their respective folder of tomcat,i am getting and error..which is as follows....
Resource not found: http://10.0.2.65:8080/servlet/ChatServlet
The configuration that i am using is:
1)win XP
2)Tomcat5.1
3)JDK 1.5
my servlet file is 'ChatServlet.class',which is placed in a package(or folder) called 'servlet'...
so i have place the whole package(servlet) in WEB-INF...
and the mapping that i have given in web.xml is as follows:
<servlet>
<servlet-name>ChatServlet</servlet-name>
<servlet-class>ChatServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ChatServlet</servlet-name>
<url-pattern>/ChatServlet</url-pattern>
</servlet-mapping>
NOW is that mapping correct??
Do you find anything wrong in the way i have put my files in Tomcat??
and also if possible please tell me for what is these mapping in web.xml used??
thanx in advance

</servlet>
<servlet-mapping>
<servlet-name>ChatServlet</servlet-name>
