And here is my register.html codes:

Here is my Register.java codes:
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class Register extends HttpServlet{
public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{
response.setContentType("text/html");
PrintWriter out=response.getWriter();
String n=request.getParameter("name");
String p=request.getParameter("password");
String e=request.getParameter("email");
String c=request.getParameter("userCountry");
try{
Connection con=DriverManager.getConnection(
"jdbc:mysql://localhost:8888", "root", "1234"
);
PreparedStatement ps=con.prepareStatement("insert into REGISTERUSER values(?, ?, ?, ?)");
ps.setString(1,n);
ps.setString(2,p);
ps.setString(3,e);
ps.setString(4,c);
int i=ps.executeUpdate();
if(i>0){
out.print("Registered successfully..");
}
}catch(Exception d){d.printStackTrace();}
out.close();
}
}
And here is my Web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<servlet>
<servlet-name>Register</servlet-name>
<servlet-class>Register</servlet-class>
</servlet>
<servlet-mapping>

<url-pattern>/register.html</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>register.html</welcome-file>
</welcome-file-list>
</web-app>
Help would be appreciated!!

Solution: Use only the form button you mapped to your servlet action. Show activity on this post. If you're still facing the issue even after replacing doGet() with doPost() and changing the form method="post" . Try clearing the cache of the browser or hit the URL in another browser or incognito/private mode.
The problem is that you mapped your servlet to /register.html and it expects POST method, because you implemented only doPost() method. So when you open register.html page, it will not open html page with the form but servlet that handles the form data.
Alternatively when you submit POST form to non-existing URL, web container will display 405 error (method not allowed) instead of 404 (not found).
To fix:
<servlet-mapping>
<servlet-name>Register</servlet-name>
<url-pattern>/Register</url-pattern>
</servlet-mapping>
Override service method like this:
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
And Voila!

I think your issue may be in the url pattern. Changing
<servlet-mapping>
<servlet-name>Register</servlet-name>
<url-pattern>/Register</url-pattern>
</servlet-mapping>
and
<form action="/Register" method="post">
may fix your problem
