Deploy servlet

Question

Hello everybody,
I am having the "famous" problem that my servlet does not start. There are many questions about this topic, and many answers, but I haven't found the right one for me.
When I am calling my servlet in my applet, I get the error message
"javax.servlet.ServletException: Wrapper cannot find servlet class SaveServlet or a class it depends on"
----- Root Cause -----
java.lang.ClassNotFoundException: SaveServlet. "
I put the SaveServlet in the WEB-INF/class directory, and obviously Tomcat finds it when starting. At least, when I just create a dummy SaveServlet-class (which is not derived from HttpServlet), Tomcat says at startup
javax.servlet.ServletException: Class servlet1.SaveServlet is not a Servlet
So it should find the class, shouldn't it?
The servlet is in a package. I am using Tomcat 4.1.31 and Java 1.5.01
This is the code of my servlet (I took everything out, so that I need only two imports):
package servlet1;
import javax.servlet.*;
import javax.servlet.http.*;
public class SaveServlet extends HttpServlet {
}and this is my web.xml:
<servlet>
  <servlet-name>SaveServlet</servlet-name>
  <servlet-class>servlet1.SaveServlet</servlet-class>
  <load-on-startup>5</load-on-startup>
</servlet>
<servlet-mapping>
        <servlet-name> SaveServlet </servlet-name>
        <url-pattern> /SaveServlet </url-pattern>
    </servlet-mapping>Has anybody an idea?
Thanks, Thea

You are using this for the URL:
http://localhost/servlet/SaveServlet?width=100&height=100
But the servlet is mapped to:
/SaveServlet.
So you should be using:
http://localhost/SaveServlet?width=100&height=100
(see, no /servlet). The /servlet is there for use with the 'invoker servlet'. It is <bad news> to use the invoker servlet, so I won't explain how to do so...
But, since you have a servlet mapping done correctly in the web.xml, the URL you use is:
http://domain:port/servletContext/servletMapping?quaryParam=value...
When you are in the ROOT context, the /servletContext becomes just "/", and your URL should be
http://localhost:8080/SaveServlet?...
got it?
