Unable to run servlet in Tomcat

Question

I've installed Tomcat and ran the examples fine, Ialso created some test jsp files and placed them in C:\tomcat\Tomcat-4.1\webapps\ROOT\test and then ran them calling http://localhost:8080/test/Hello.jsp which worked fine. When I place servlets into the same folder and call it, I get a 404. Do I need to set something in the web.xml file and if so please show and example.

Answer 1

I've got a problem under Tomcat 4.1.27 - 5 . I wrote a Servlet and when I call it as an action in a form I get the message:
The requested resource (/G2Mweb/marketing/inseriscicampagnaservlet) is not available.
My web.xml contains the correct tags that define it:
<servlet>
<servlet-name>inseriscicampagnaservlet</servlet-name>
<servlet-class>servlet.InserisciCampagnaServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>inseriscicampagnaservlet</servlet-name>
<url-pattern>/inseriscicampagnaservlet</url-pattern>
</servlet-mapping>
Caller line in jsp file:
<form action="inseriscicampagnaservlet" method="POST">
I wrote other servlets that run without problems. The only difference between this and the others is that I created this in the wrong directory and then move it in /servlet.
Any idea of what's happening?
Thanks in advance
