Create and save an XML document at the server,which contain some users information.write a program,which takes user id as an input and returns the user details by taking the user information from the XML document.

4. Develop a javabean which gives the exchange value of INR(Indian rupees) into equivalent American/canadan/Australian dollor value. Indian.java : package currency; import java.beans.*; import java.awt.*; import java.awt.event.*; public class Indian extends Canvas { private double rupees; private String other; public Indian() { setSize(200,25); other="America"; } public void setRupees(double amount) { rupees=amount; repaint(); } public double getRupees() { return rupees; } public void setOther(String other) { this.other=other; repaint(); } public String getOther() { return other; } public void paint(Graphics g) { if(other.equals("America")) { g.drawString(String.valueOf(rupees/42),20,20); } elseif(other.equals("Australia")) { g.drawString(String.valueOf(rupees/27),20,20); } else if(other.equals("Canada")) { g.drawString(String.valueOf(rupees/35),20,20); } else g.drawString("I Can't convert for such country",20,20); } } currency.mft : Manifest-Version: 1.0 Java-Bean: True Name: currency/Indian.class Created-By: 1.6.0 (Sun Microsystems Inc.) OUTPUT : Initially the beans window will be, India 550 rs converted into US dollorand shown in Beanbox window like 13..095 India 550 rs converted into Australia dollor and shown in Beanbox window like To select different country we have to enter in highlited space, 5. Create two beans traffic light(only 3 colors –red,green,yellow)and automobile(implemented as a Textbox which states its state/movement).the state of the Automobile should depend on the following Light Transition Table. Light Transition Automobile State Red ->yellow Ready Yellow ->Green Move Green ->Red Stopped TrafficPerson : package demo; import java.awt.Panel; import java.awt.event.*; import java.io.PrintStream; import java.io.Serializable; import javax.swing.JTextField; import java.beans.*; public class TrafficPerson extends Panel implements Serializable, PropertyChangeListener { public TrafficPerson() { tx = new JTextField(12); state="Ready"; tx.setHorizontalAlignment(JTextField.LEFT); tx.setText("Ready"); tx.setEnabled(false); add(tx); } public void change() { if(state.equals("Ready")) { state="Move"; tx.setText(state); } elseif(state.equals("Move")) { state="Stopped"; tx.setText(state); } elseif(state.equals("Stopped")) { state="Ready"; tx.setText(state); } } public void propertyChange(PropertyChangeEvent e) { change(); } private JTextField tx; private String state; } TraficLight : package mypack; import java.awt.*; import java.beans.*; import java.io.*; import java.util.Date; public class TrafficLight extends Panel implements Runnable, Serializable, PropertyChangeListener { public TrafficLight() { setSize(50, 50); color = Color.red; label = new Label(); label.setSize(100,100); label.setBackground(Color.red); add(label); changes = new PropertyChangeSupport(this); changes.addPropertyChangeListener(this); interval = 5; runner = new Thread(this); runner.start(); } public void addPropertyChangeListener(PropertyChangeListener propertychangelistener) { changes.addPropertyChangeListener(propertychangelistener); } public void removePropertyChangeListener(PropertyChangeListener propertychangelistener) { changes.removePropertyChangeListener(propertychangelistener); } public int getInterval() { return interval; } public void setInterval(int i) { interval = i; if(runner != null) runner.interrupt(); } public int getSeconds() { return (int)((new Date()).getTime() / 1000L); } public void run() { int i = getSeconds(); do { try { Thread.sleep(interval * 1000); } catch(InterruptedException interruptedexception) { } int j = getSeconds(); changes.firePropertyChange("seconds", new Integer(i), new Integer(j)); i = j; } while(true); } public void propertyChange(PropertyChangeEvent propertychangeevent) { if(color == Color.red) { label.setBackground(Color.orange); color = Color.orange; } else if(color == Color.orange) { label.setBackground(Color.green); color = Color.green; } else if(color == Color.green) { label.setBackground(Color.red); color = Color.red; }} private Color color; private Label label; private PropertyChangeSupport changes; private int interval; transient Thread runner; } TraficLight.mft : Manifest-Version: 1.0 Name: mypack/TrafficLight.class Java-Bean: True TraficPerson.mft : Manifest-Version: 1.0 Java-Bean: True Name: demo/TrafficPerson.class Created-By: 1.6.0 (Sun Microsystems Inc.) OUTPUT : After setting TrafficLight and changing interval to 10 sce.. After setting the TrafficPerson,TrafficLight in the BeanWindow….. the light is changing to yellow,,,,the person window is showing ready…. 6. Install TOMCAT web server. Convert the static webpages of assignments 2 into dynamic webpages using servlets and cookies. Hint: Users information (user id, password, credit card number) would be stored in web.xml. Each user should have a separate Shopping Cart. 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.xml Next place all the class files under the classes and jar files(servletapi.jar,classes12.jar etc…) under lib subdirectories. After this start tomcat by giving the following command at the instll_dir>tomcat>bin Catalina.bat run At the I.E(web browser) give the url as http;//localhost:8080//tr/htmlfile or servlet url pattern Portno 8080 is assigned for the tomcat.

Redo the previous task using JSP by converting the static web pages of assignments 2 into dynamic web pages. Create a database with user information and books information and books information. The books catalogue should be dynamically loaded from the database. Follow the MVC architecture while doing the website. 1) 2) 3) 4) Create your own directory under tomcat/webapps (e.g. tr1) Copy the html files in tr1 Copy the jsp files also into tr1 Start tomcat give the following command Catalina.bat run At install-dir/bin 5) at I.E give url as http://localhost:8081/tr1/main.html Main.html:
