First of all putting some servlets in a folder under webapps won't nessasarily 
work. At the very least you need the following structure:

/WEB-INF directory
/WEB-INF/classes directory
/WEB-INF/web.xml file

The web.xml file can be very minimal, but is required in order for tomcat to 
recognise it as a web application. Also, how are you calling the servlet? If 
you want to call a servlet directly it usually looks somthing like:

http://localhost:8080/test/servlet/com.foo.MyTestServlet

However, if you want to have a more friendly URL you can create a mapping in 
the web.xml file like this:

	<servlet>
		<servlet-name>test</servlet-name>
		<servlet-class>com.foo.MyTestServlet</servlet-class>
	</servlet>

	<servlet-mapping>
		<servlet-name>test</servlet-name>
		<url-pattern>test</url-pattern>
	</servlet-mapping>

Peter
