00.01 Hii everyone.
00.02 Welcome to the tutorial on Integrating an Applet in a Web Application
00.08 The application that you build in this tutorial shows you how to build and deploy applets in the Netbeans IDE.
00.16 If this is the first time you are using Netbeans, please view the tutorials,
00.21 Introduction to Netbeans, to get started with the IDE.
00.25 Also view the tutorials Developing Web Applications and Designing GUIs on Netbeans
00.32 to get familiarised with the IDE.
00.36 All the above tutorials can be viewed on the spoken tutorial website
00.41 For this demonstration, I am using the Linux Operating System Ubuntu v11.04 and Netbeans IDE v7.1.1
00.55 In this tutorial, we will
00.57 Create an Applet
00.59 Run the Applet; and
01.02 Embed the applet in a web application
01.05 Let us now launch the IDE to create our project.
01.10 Go to File>New Project and create a Java Class Library


01.17 Click Next'


01.19 Give your Project a name
01.21 I will name my Project as SampleApplet.
01.26 Set the Location to any directory on your system


01.30 And Click Finish to create your project
01.34 Let us Next create the Applet Source File
01.39 Right-Click on the SampleApplet project node
01.42 and choose Properties to open the Properties window.
01.47 Select the desired Source and Binary Format for the project.
01.53 This is to make sure if the correct version of the JDK has been chosen.
01.59 For example, if you choose the latest version of JDK,
02.04 then the applet might not run on machines that have an older version of the Java browser plugin.
02.10 I will select the latest version of JDK since my browser supports the latest version of the java browser pluggin
02.19 Click on OK
02.21 Right-Click again on the SampleApplet project node
02.25 and select New >Applet
02.29 If you do not find the applet option in this contextual menu, Click on Other
02.35 Under Categories, select Java.
02.38 And Under File Types, select Applet to create an Applet
02.43 Give the Class name as Sample and the Package as org.me.hello
02.55 Click Finish
02.57 The IDE creates the applet source file in the specified package.
03.02 You can expand the Source Package node in the Projects window to see this.
03.08 The Applet source file opens in the source editor.
03.12 Let us now define our applet class.
03.17 I have the code for a simple applet,
03.21 that sets the background color to cyan,
03.24 the foreground color to red,
03.27 and displays a message that illustrates the order in which the methods in the applet,


03.34 i.e. the init() method, the start() method, and the paint() methods are called, when the applet starts up.
03.43 I will copy the entire code on my clipboard and paste it over the existing code in the IDE.
03.54 Right-Click on the Sample.java file in the Projects window,
04.00 and choose Run File from the contextual menu.
04.04 The Sample.html launcher file, with the applet embedded, is created in the build folder,
04.13 which you can see in the Files window.
04.15 Sample dot html file
04.18 The Applet is also launched in the Applet viewer.
04.23 With the message display on the screen
04.27 Let me close the appletviewer
04.29 And let us next embed the Applet in a Web Application
04.33 So that we can make the applet available to the user


04.37 To do so, we create a Web Application,
04.42 Under Categories select java web and under Projects select Web application
04.48 and Click Next


04.50 We wll name our Project as HelloSampleApplet and
05.01 Click Next
05.03 See if the correct server is selected and click Finish to create your Project
05.12 Note that, when we add the Java project SampleApplet to the web project HelloSampleApplet
05.20 we enable to IDE to build the applet whenever we build this web application.
05.26 Therefore, when we modify the Sample dot java applet
05.34 the IDE builds a new version of the applet whenever this is built.
05.40 Now In the Projects window, right-click the HelloSampleApplet project node,
05.45 and Click on Properties
05.49 Our applet is in a Java project,
05.52 To add the Jar file select the Packaging option from the menu on the left side of the window
05.59 click on Add Project and select the java project that contains the Applet class
06.05 In this case it is SampleApplet
06.09 Click on Add Project Jar Files
06.14 The JAR file containing the applet source file is now listed in the table
06.20 Click on OK
06.24 And let us build the HelloSampleApplet project now by right clicking on it in the Projects Window
06.31 and selecting Clean and Build options
06.36 Now when this project is built the applets Jar file is generated in the original SampleApplet Project
06.45 Go to the Files Window expand the HelloSampleApplet Project node
06.51 Under build and web folder
06.54 You can see that the jar file has been added
06.58 Now Let us next embed the applet in a HTML file,


07.02 Go back to the Project Window, right-click on the HelloSampleApplet project node,
07.09 choose New and select the HTML file option
07.13 If you cannot find the HTML option in this contextual menu
07.18 Click on Other
07.21 Select Web under Categories and select HTML under File Types and click Next
07.29 Give your Html file a name
07.32 I will name the file as MyApplet and Click on Finish.
07.40 The next step is to enter the applet tag in between the body tags in MyApplet dot html file
07.48 I have the applet code here
07.51 Let me copy it onto my clipboard and paste it in between the body tags in the html file
08.03 The Next step is to run the html file
08.07 Right click on MyApplet dot html in the project windows and select Run File
08.14 The server deploys the html file in the IDE default browser
08.25 Now the server as deploy the html file in the IDE's default browser
08.30 You can see the message displayed across the screen
08.36 Now to the assignment
08.38 As your assignment create another simple banner applet in the IDE,
08.43 where the applet scrolls a message across the applet's window.
08.49 Embed your applet in a web application,
08.52 and add JAR files to the web project and,
08.56 finally create and run the HTML file.
09.00 I have created my own moving banner applet
09.04 Let me open the project and run it
09.18 You can see that the applet has opened with the message scrolling across the Window
09.28 Watch the video available at the link shown on the screen.
09.32 It summarizes the Spoken Tutorial project.
09.36 If you do not have good bandwidth, you can download and watch the videos.
09.41 The Spoken Tutorial project team conduct workshops using Spoken Tutorials.
09.46 Gives certificates to those who pass an online test.
