I'm trying to create the first servlet in tomcat following many examples on the internet but always gives me error 404. I already checked for other solutions but I don't understand the main problem.(sometimes give me error 500 also)
link:
http://localhost:8080/Servlet/Hello
folder:
\--Tomcat
\--webapps
\--Servlet
\--WEB-INF
\--web.xml
\--classes
\--HelloWorld.class
\--HelloWorld.java
HelloWorld.java:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World copy!</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello World copy!</h1>");
out.println("</body>");
out.println("</html>");
}
}
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
-<web-app xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/j2ee" version="2.4">

<servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
