Running servlet

[nebulom]

I'm using Eclipse and wanted to run a simple servlet. I made a project on the workspace as you can see on the attached image. And got a code on WEB-INF/src on temp project

package net.nevyn.brownmonkey;
 
import java.io.IOException;  
import java.io.PrintWriter;     
 
import javax.servlet.ServletException;
 
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
public class FirstServlet extends HttpServlet{
    public void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException,IOException{
        PrintWriter out=response.getWriter();
        out.println("Hello World");
        out.close();
    }
}

How do I run the FirstServlet? Can't seem to find an answer. All I found on the net was putting my class to ROOT/WEB-INF/classes on Tomcat's installed folder. Any articles or links for this stuff is very well accepted and thanked.

Thank you so much.
