i face Error 403 FORBIDDEN what to do now?

in the firstservlet.java i write only the following code

package first; 
import java.io.IOException; 
import javax.servlet.http.*; 
public class FirstServlet extends HttpServlet { 
  /** 
  * 
  */ 
  private static final long serialVersionUID = 1L; 
  public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {
    resp.setContentType("text/plain"); 
    resp.getWriter().println("Hello, world"); 
  } 
} 

whats the wrong??

Answer 1

403 Forbidden is a HTTP status code returned by a web server when a user agent requests a resource that the server does not allow them to

(wikipedia)

The server is up and running, accepted you request but can't respond because you're not allowed to access some resource. So the problem is inside the Firstapplication, maybe this aplication trys to access some file system resources and the server does not have sufficient privileges.
