I have developed an J2EE application that allows people to watch video. This implementation is working fine for desktop browsers. Videos for the Browser are currently encoded in MP4 format and have been tested to work. When someone hits a video URL we have a Video servlet thats writes the bytes to the response. The code is given below:

MIME types to play the video's :

video/mpeg: MPEG-1 video with multiplexed audio; Defined in RFC 2045 and RFC 2046

video/mp4: MP4 video; Defined in RFC 4337

video/ogg: Ogg Theora or other video (with audio); Defined in RFC 5334

video/quicktime: QuickTime video;

video/webm: WebM Matroska-based open media format

video/x-matroska: Matroska open media format

video/x-ms-wmv: Windows Media Video; Documented in Microsoft KB 288102

video/x-flv: Flash video (FLV files)

Here is the example code to test Video functionality using servlet :

This is VideoServlet.java main class having the application business logic.

 
    
package com.cv.servlet.video.play;



import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;



import javax.servlet.ServletContext;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



/**

 * Servlet implementation class VideoServlet

 *

 *

 */



public class VideoServlet extends HttpServlet {

  private static final long serialVersionUID = 1L;



  /**

   * @see HttpServlet#HttpServlet()

   */

  public VideoServlet() {

    super();



  }



  /**

   * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse

   *      response)

   */

  protected void doGet(HttpServletRequest request,

      HttpServletResponse response) throws ServletException, IOException {



    String fileName = request.getParameter("filename");

    fileName = "/"+fileName + ".mp4";

    ServletContext ct = getServletContext();

    InputStream input = ct.getResourceAsStream(fileName);

    //response.setContentType("video/quicktime"); //Use this for VLC player

    response.setContentType("video/mp4");



    response.setHeader("Content-Disposition", "inline; filename=\""

        + fileName + "\"");

    OutputStream output = response.getOutputStream();



    byte[] buffer = new byte[2096];

    int read = 0;

    while ((read = input.read(buffer)) != -1) {

      output.write(buffer, 0, read);

    }

    input.close();

    output.flush();

    output.close();



  }



  /**

   * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse

   *      response)

   */

  protected void doPost(HttpServletRequest request,

      HttpServletResponse response) throws ServletException, IOException {

    doGet(request, response);

  }



}

This is index.html view file and making this as a welcome file for the application.

Hi Great article.
Does it support, video pause, video forward operations on the video when it is playing in browser?

You may have the technology to assemble a superior mousetrap, yet in the event that you have no mice or the old mousetrap functions admirably, there is no chance and afterward the technology to fabricate a superior one gets superfluous. IT company North York
