Download YouTube Videos and Replay the Videos From Disk

To many times I have seen my favorite graphic or media files disappear from the Internet. Following is instructions to save your favorite YouTube videos to your hard drive.

Steps:
1. Download a special player, an FLV player from http://applian.com/flvplayer/. Install it. Note, I first checked it for viruses, and there were none.
2. Download your videos. I used the site http://www.youtubecatcher.com/.
2.1 First, I went to YouTube.com to get the URL for for the video I wanted to download.
Example: http://youtube.com/watch?v=uswYdQqHC6s
2.2 Second, copy the URL into YouTubeCatcher, and click Download. Save the file to disk, and give it a file name with the extension .flv, example, jeepney.flv.
3. Play the video file you saved to disk using the FLV Player.

NetBean Project Distribution

This blog describes packaging a NetBeans project for others to download, install, edit, and run from their NetBeans IDE. To prepare a NetBeans project for distribution:
* Copy to the project directory to a work directory.
* Delete the directories: build, dist, nbproject/private, and any directory not used, example the test directory.
* Zip the directory up.
Now anyone with NetBeans, can:
* Download the project zip file.
* Unzip the file into a directory.
* Open the project, edit it, and run it.

Note, if you are distributing a project that requires a NetBeans plugin, example the jMaki plugin, include the same version of the plugin into the zip file.
Example package directory:

.../jMakiProject1
.../jMakiProject1/nbproject
.../jMakiProject1/src
.../jMakiProject1/web
.../jMakiProject1/0-setup
.../jMakiProject1/0-setup/readme.txt
.../jMakiProject1/0-setup/org-netbeans-modules-sun-jmaki.nbm

The goal is a complete set of files and instructions for the user to have a successful experience.

Ajax Call Updated

Ajax is when:
A web browser event causes a JavaScript program to make a call to the server.
The server returns a response, and the JavaScript program handle the response, for example, by posting the response onto the browser.

In my Web 2.0 course, I updated the Ajax call because a student, Charles Phillips, in Washington, DC, USA, pointed that I need to handle Microsoft's newest browser, I.E.7. Thank you Charles.

Following is a description of Ajax demonstration code, a JavaScript program, an HTML file, and a server side JSP.
Click here, to download the complete files. If you are using NetBeans, unzip the file, and open and run in NetBeans 5.5 or higher.

Below is the updated JavaScript Ajax call.

var http = createRequestObject();
function createRequestObject() {
    var theRequestObject;
    if (window.XMLHttpRequest) { // Firefox, others...
        theRequestObject = new XMLHttpRequest();
    } else if (window.ActiveXObject) { // IE
        try {
            theRequestObject = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                theRequestObject = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
        }
    }
    if (!theRequestObject) {
        alert('Error: the Request Object is not created.');
        return false;
    }
    return theRequestObject;
}

Below is the JavaScript code which uses the above Ajax object, http.
1. A URL is set in the object, http, using http.open.
2. The function processResponse() is set in the object, http, to process the response from the server, using http.onreadystatechange.
3. An http call is made to the server by the Ajax object, http, using http.send.

The function processResponse() is called when there is a state change in the Ajax call. The first state handled, (http.readyState == 1), is the state where the web browser is waiting for a response from the server. When there is a response, http.readyState == 4, this code handles the HTTP responses 404, 500, and 200, which are the most common responses.

function validateUserId() {
    document.getElementById('msgCall-1').innerHTML = 
       'Called: validateUserId: ' + document.getElementById('userId').value;
    // sample: http://localhost:8080/AjaxValidate1/validateData.jsp?userId=duke
    http.open('get', 'validateData.jsp?userId='+ document.getElementById('userId').value);
    http.onreadystatechange = processResponse;
    http.send(null);
}
function processResponse() {
    var count = 0;
    if(http.readyState == 1) {
        document.getElementById('msgCall-2').innerHTML = 'Waiting for response...';
    }
    if(http.readyState == 4) {
        if (http.status == 404) {
            document.getElementById('msgCall-2').innerHTML = 
                 '*** Error, URL:' + http.statusText + ' ***';
        }
        else if (http.status == 500) {
            document.getElementById('msgCall-2').innerHTML = 
                 '*** Error 500, statusText:' + http.statusText + ' ***';
        }
        else if (http.status == 200) {
            document.getElementById('msgCall-2').innerHTML = 
                 'Ajax response: '+http.responseText;
        }
    }
}

Below is the HTML code. The event to trigger the Ajax call, is the button Make Ajax Call.

<html>
    <head>
        <title>Ajax:Validate</title>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <script src=ajaxCall.js></script>
    </head>
    <body>
        <h1>Ajax call to Validate a User ID</h1>
        User ID: <input type="text" id="userId" value="Duke">
        <br><button onclick="Javascript:showUserId();">
                 Show User ID</button>
        <br><button onclick="Javascript:validateUserId();">
                 Make Ajax Call</button>
        <p>
        <div id=msgCall-1 style="font-size: 25px;">Debug message 1.</div>
        <div id=msgCall-2 style="font-size: 25px;">Debug message 2.</div>
    </body>
</html>

Below is the JSP code to handle the Ajax call.

<%
    ServletContext app = getServletContext();
    RequestDispatcher disp;
    if ( (request.getParameter("userId")==null || 
          request.getParameter("userId")=="" ) )
    {
        out.print("invalid: Requires userid." );
        return;
    }
    if ( request.getParameter("userId").compareTo("Duke")==0 )
    {
        out.print("Invalid" );
        return;
    }
    out.print("valid" );
%>
