Jetty: Configuring many connectors

In previous post, I explained how to configure a connector to handle http requests. In this post, I am going to explain, how to configure multiple connectors. In this post, I am going to configure two connectors, one listens http and other listens https requests.

‘http’ request is straight forward, as I shown in previous post. But for https requests, you need a trusted certificate. Java provides command line tool 'keytool' to generate security certificates.

Following post, explains how to generate keystore.

Following is the complete working application.

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.server.handler.AbstractHandler;

public class HelloHandler extends AbstractHandler {
  public HelloHandler() {

  }

  public void handle(String target, Request baseRequest,
      HttpServletRequest request, HttpServletResponse response)
      throws IOException, ServletException {
    response.setContentType("text/html; charset=utf-8");
    response.setStatus(HttpServletResponse.SC_OK);

    PrintWriter out = response.getWriter();
    out.println("Welcome to Jetty embeddey programmng");
    baseRequest.setHandled(true);
  }
}

    Server server = new Server();

    HttpConfiguration http_config = new HttpConfiguration();

    server.setConnectors(new Connector[] { http, https });

    server.setHandler(new HelloHandler());

    server.start();
    server.join();
  }
}

Run above application and hit the url ‘http://localhost:8080/’, you will get following screen.

hit the url ‘https://localhost:8443/’, you will get other screen.
