404 Not Found : Servlet not found on this server

Question

I have been trying to run a simple servlet from a JSP page. For some reason I keep getting an error informing me that the servlet in question cannot be found on the server. I have incuded some code from my project in the hope that it may provide a clue to the problem. I would appreciate any help.
from the web.xml file
<servlet>
<servlet-name>MapTestServlet</servlet-name>
<servlet-class>Common.MapTestServlet</servlet-class>
</servlet>
from the JSP page
<FORM ACTION="\PATSCoreROC\classes\Common.MapTestServlet" METHOD="post">
<INPUT TYPE="SUBMIT" NAME="Test" VALUE="Test Servlet">
</FORM>
Clicking the Test Servlet button produces the following 404 error in the browser
404 Not Found
Resource /PATSCoreROC/classes/Common.MapTestServlet not found on this server

Answer 1

After a little work and some coffee I tried the following and it resolved my problem.
<FORM ACTION="servlet\Common.MapTestServlet" METHOD="post">
<INPUT TYPE="SUBMIT" NAME="Test" VALUE="Test Servlet">
</FORM>
I should have included 'servlet\' in the ACTION property.
