Just set the proper content type and content length, and copy the contents of the file to the servlet's output stream.

Hello Rob,

Thank you for your reply. I did that already. May be I didn't explained my question properly.
What you said will work but only once, I mean you won't have to seek video, because it's depend on outputstream.

Do I need any video server or something, for example

I have
<video><source src="http://video.abhishek.com?id=1&encrypt=........"></source></video>

so this will hit my server and grab video to play. All videos are stored in mnt drive (not in same webserver).

Please guide me thanks

You said you wanted your site to be "like youtube". Okay: what does YouTube do? You can see their HTML, can't you?

Hello Paul,

May be I didn't clear my requirements properly . Here what I want.

I have like TB's of video stored in mnt drive.
Each video has it name stored in DB. So my video list page shows all videos link like <a href="video.abhishek.com?id=<id>&encrypt=<key>>${video.VideoName}</a>
Now when I'll click any link it will go to Servlet which will pull video from mnt drive and and dispatch to a jsp page so that I can use this

<video><source src="video.abhishek.com/samplevideo.mp4"></video>

I can able to do this if my video is stored on web directory but as I mentioned all my videos are in a separate drive

I dont' know if I want youtube of any thing, but wat I mentioned is my requirement.

Please Help

Okay. So like Rob already said, have your servlet copy the contents of the video to its output stream. I don't see why it makes any difference where the video is actually stored as long as the servlet code knows where it is.

String videoUrl = "../videos/"+"abhishek"+"/"+"videos"+"/"+batchName+"/"+videoName+"/200";
HTML video = new HTML("<video id=\"my_video_1\" class=\"video-js vjs-default-skin\" controls preload=\"auto\" width=\"640\" height=\"264\" data-setup=\"{}\">"+
"<source src="+videoUrl+" type='video/mp4'></video>");


here videos is my servlet


String videoPath= "C:/mnt/bigvol/WebImages/videos/2011/clips/";
String videoName= "L_00010.mp4";
ServletContext application= getServletConfig().getServletContext();
File file = new File(videoPath,videoName);


String contentType = getServletContext().getMimeType(file.getName());
response.setBufferSize(DEFAULT_BUFFER_SIZE);
response.setHeader("Content-Type", "video/mp4");
response.setHeader("Content-Length", Long.toString(file.length()));
response.setHeader("Content-Disposition", "inline; filename=\"" + file.getName() + "\"");

// Prepare streams.
BufferedInputStream input = null;
ServletOutputStream outputStream = response.getOutputStream();
BufferedOutputStream output = null;
try {
// Open streams.
byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);
output = new BufferedOutputStream(response.getOutputStream(), DEFAULT_BUFFER_SIZE);

// Write file contents to response.

int length;
while ((length = input.read(buffer,0,4096)) != -1) {
outputStream.write(buffer, 0, length);
}
} finally {
// Gently close streams.
// close(output);
// close(input);
try{
if(input != null)
input.close();
}catch (Exception e) {
// TODO: handle exception
}
if(outputStream != null)
outputStream.flush();
}

I cannot seek forward or backward and once played I cant play again .
I can setup a new server to serve video I read something like HTTP pusedstreaming etc.

Is I am in right direction ??

Here's a link to a tutorial on building a video display portlet for Liferay 5.2. I know you aren't building a portlet, but some of the concepts there may be useful to you.

Blog Page

There's also a downloadable portlet project for Liferay 6.0 where you can actually get the source code for it.

It is sorta covered in the JavaRanch Style Guide.
