AIM4. Write a program illustrating various methods in cascading style sheets.

1) Use different font, styles2) Set a background image3) Control the repetition of the image4) Define styles for links5) Work with layers6) Add a customized cursor

DESCRIPTION: Design a web page using CSS (Cascading Style Sheets) which

includes the following:

1) Use different font, styles: In the style definition you define how each selector should work (font, color etc.).Then, in the body of your pages, you refer to these selectors to activate the styles.

2) Set a background image for both the page and single elements on the page. You can define the background image for the page like this:

3) Control the repetition of the image with the background-repeat property.

As background-repeat: repeat

4) Define styles for links as

5) Work with layers:

6) Add a customized cursor:

Selector {cursor:value}

.xlink {cursor:crosshair}

.hlink{cursor:help}

AIM :5.Developing a Simple Bean Using the BDK:This section presents an example that shows how to develop a simple Bean and connect it to other components via the BDK.Our new component is called the Colors Bean. It appears as either a rectangle orellipse that is filled with a color. A color is chosen at random when the Bean beginsexecution. A public method can be invoked to change it. Each time the mouse is clickedon the Bean, another random color is chosen. There is one boolean read/write propertythat determines the shape.The BDK is used to lay out an application with one instance of the Colors Bean andone instance of the OurButton Bean. The button is labeled “Change.” Each time it ispressed, the color changes.

SOFTWARE DEVELOPMENT USING JAVA

Create a New BeanHere are the steps that you must follow to create a new Bean:1. Create a directory for the new Bean.2. Create the Java source file(s).3. Compile the source file(s).4. Create a manifest file.5. Generate a JAR file.6. Start the BDK.7. Test.

The following sections discuss each of these steps in detail.

Create a Directory for the New BeanYou need to make a directory for the Bean. To follow along with this example, createc:\bdk\demo\sunw\demo\colors. Then change to that directory.The Colors and OurButton BeansCreate the Source File for the New Bean

The source code for the Colors component is shown in the following listing. It islocated in the file Colors.java.

The import statement at the beginning of the file places it in the package namedsunw.demo.colors. Recall from Chapter 9 that the directory hierarchy corresponds tothe package hierarchy. Therefore, this file must be located in a subdirectory namedsunw\demo\colors relative to the CLASSPATH environment variable.

The color of the component is determined by the private Color variable color, andits shape is determined by the private boolean variable rectangular.The constructor defines an anonymous inner class that extends MouseAdapter and



overrides its mousePressed( ) method. The change( ) method is invoked in response tomouse presses. The component is initialized to a rectangular shape of 200 by 100 pixels.

The change( ) method is invoked to select a random color and repaint the component.The getRectangular( ) and setRectangular( ) methods provide access to the oneproperty of this Bean. The change( ) method calls randomColor( ) to choose a color andthen calls repaint( ) to make the change visible. Notice that the paint( ) method uses therectangular and color variables to determine how to present the Bean.

// A simple Bean.package sunw.demo.colors;import java.awt.*;import java.awt.event.*;public class Colors extends Canvas {transient private Color color;private boolean rectangular;public Colors() {addMouseListener(new MouseAdapter() {public void mousePressed(MouseEvent me) {change();}});rectangular = false;setSize(200, 100);change();}public boolean getRectangular() {return rectangular;}public void setRectangular(boolean flag) {this.rectangular = flag;repaint();}public void change() {SOFTWARE DEVELOPMENTUSING JAVAcolor = randomColor();repaint();}private Color randomColor() {int r = (int)(255*Math.random());int g = (int)(255*Math.random());int b = (int)(255*Math.random());return new Color(r, g, b);



}public void paint(Graphics g) {Dimension d = getSize();int h = d.height;int w = d.width;g.setColor(color);if(rectangular) {g.fillRect(0, 0, w-1, h-1);}else {g.fillOval(0, 0, w-1, h-1);}}}

Compile the Source Code for the New BeanCompile the source code to create a class file. Type the following:javac Colors.java.Create a Manifest File.

You must now create a manifest file. First, switch to the c:\bdk\demo directory. Thisis the directory in which the manifest files for the BDK demos are located. Put thesource code for your manifest file in the file colors.mft. It is shown here:Name: sunw/demo/colors/Colors.classJava-Bean: True

This file indicates that there is one .class file in the JAR file and that it is a Java Bean.Notice that the Colors.class file is in the package sunw.demo.colors and in thesubdirectory sunw\demo\colors relative to the current directory.Generate a JAR File

Beans are included in the ToolBox window of the BDK only if they are in JAR files in thedirectory c:\bdk\jars. These files are generated with the jar utility. Enter the following:jar cfm ..\jars\colors.jar colors.mft sunw\demo\colors\*.classThis command creates the file colors.jar and places it in the directory c:\bdk\jars.(You may wish to put this in a batch file for future use.)Start the BDK

Change to the directory c:\bdk\beanbox and type run. This causes the BDK to start.You should see three windows, titled ToolBox, BeanBox, and Properties. The ToolBoxwindow should include an entry labeled “Colors” for your new Bean.Create an Instance of the Colors Bean

After you complete the preceding steps, create an instance of the Colors Bean in the



BeanBox window. Test your new component by pressing the mouse anywhere withinits borders. Its color immediately changes. Use the Properties window to change therectangular property from false to true. Its shape immediately changes.Create and Configure an Instance of the OurButton BeanCreate an instance of the OurButton Bean in the BeanBox window. Then followthese steps:1. Go to the Properties window and change the label of the Bean to “Change”.You should see that the button appearance changes immediately when thisproperty is changed.2. Go to the menu bar of the BeanBox and select Edit | Events | action |actionPerformed.3. Move the cursor so that it is inside the Colors Bean display area, and click theleft mouse button. You should see the Event Target Dialog dialog box.4. The dialog box allows you to choose a method that should be invoked whenthis button is clicked. Select the entry labeled “change” and click the OK button.You should see a message box appear very briefly, stating that the tool is“Generating and compiling adaptor class.”5. Click on the button. You should see the color change.You might want to experiment with the Colors Bean a bit before moving on.

Output:



Create two Beans Traffic Light(implemented as a label with only three background colors-red, green, yellow) and Automobile(Implemented as a Text Box which states its state/movement). The state of the Automobile should depend on the following Light Transition table./*<applet code="Sig.class" height=300 width=200></applet>*/import java.awt.*;import java.lang.String;import java.awt.event.*;import java.applet.Applet;import java.applet.*;

r2.addItemListener(this);r3.addItemListener(this);

}public void paint(Graphics g) {

g.setColor(Color.red); g.drawOval(10, 30, 20, 20); //System.out.println(s1); g.setColor(Color.yellow); g.drawOval(10, 60, 20, 20); g.setColor(Color.green); g.drawOval(10, 90, 20, 20); s1=cbg.getSelectedCheckbox().getLabel(); if(s1=="red") { g.setColor(Color.red); g.fillOval(10, 30, 20, 20); } else if(s1=="yellow") { g.setColor(Color.yellow); g.fillOval(10, 60, 20, 20);



} else if(s1=="green") { g.setColor(Color.green); g.fillOval(10, 90, 20, 20); }

} public void itemStateChanged(ItemEvent ie) {

AIM:6. Install TOMCAT web server. Convert the static webpages of assignments 2 intodynamic webpages using servlets and cookies. Hint: Users information (user id,password, credit card number) would be stored in web.xml. Each user should havea separate Shopping Cart. PROCEDURE:First install the tomcat into the system.Then make a subdirectly(eg., tr) in the \tomcat\webapps.Under tr create WEB-INF directory and also place the html files in this tr directory only.Next under WEB-INF create two subclasses lib,classes and web.xmlNext place all the class files under the classes and jar files(servlet-api.jar,classes12.jaretc…) under lib subdirectories.After this start tomcat by giving the following command at the instll_dir>tomcat>binCatalina.bat runAt the I.E(web browser) give the url as http;//localhost:8080//tr/htmlfile or servlet urlpatternPortno 8080 is assigned for the tomcat.
