How to run servlet on vps?

Question

Java

Hello, I decided that learning Java would be more productive and enjoyable on a VPS, and I ran into a problem that I can’t find a solution to. In fact, the problem is not complicated, but I'm missing something, help, please.

There is a VPS (ubuntu), it has tomcat7 and nginx. The /var/lib/tomcat7/webapps/simple folder contains the project itself. /var/lib/tomcat7/webapps/simple/WEB-INF/classes/Servlets contains the file

MyServlet.java after clicking on it, it redirects to the myServlet page with a 404 error. On the local machine (win8) everything works. Do I need to compile anything at all before running it on the server? Maybe I misconfigured something?

servlet listing MyServlet.java

package Servlets;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
 
public class MyServlet extends HttpServlet {
    public void doGet(HttpServletResponse response,
                      HttpServletRequest) throws IOException, ServletException {
        response.setContentType("text/html");
        response.setStatus(HttpServletResponse.SC_OK);
        PrintWriter out = response.getWriter();
        out.write("<h1>Hello!</h1>");
        out.flush();
        out.close();
    }
}

web.xml listing:

<servlet>
     <servlet-name>myServlet</servlet-name>
     <servlet-class>Servlets.MyServlet</servlet-class>
 </servlet>
<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/myservlet</url-pattern>
</servlet-mapping>

upd: I found a description of Java Server-Side Programming , everything worked, it remains to deal with nginx, for some reason it does not want to work with servlets.

Answer 1

Everything worked.
Perhaps someone will need to configure nginx to work with apache and tomcat servers... ;
And a description of the creation of the Java Server-Side Programming project

Answer 2

I have a suspicion that you do not know about WAR archives.
WAR

PS: .java files are not executable - they are just a text file on the basis of which the executable code is compiled - files with the .class extension.
Yes, and packages are usually called with a small letter.

Answer 3

Yes, here you need to learn the basics first, and then write servlets.
