- 21. 18 DATE: AIM: To write a html program for invoking servlet using html. ALGORITHM: Step1: In html program, define the html, head and title tag. Step2: Then the title is Student Information Form and close the title and head tag. Step3: Define the body tag inside the body tag create form and table simultaneously. Step4: The table consists of following information Roll no, Student name, Address, Phone no and total marks. Step5: In the servlet program, import the summary package and create a ownservlet class extends with generic servlet. Step6: In the service method defined to request and response. Step7: Create the object and for print writer and get writer()value. Step8: The enumeration object get the servlet request parameter. Step9: Create objects for string method and it is displayed another object valuereceived get parameter of name received and displayed the value received value. PROGRAM: //index.jsp <html> <head> <title>Processing get requests with data</title> </head> <body> <form action = "Servlet3" method = "get"> <b><p><label>Enter Your name Please!! <br /> <input type = "text" name = "firstname" /> <input type = "submit" value = "Submit" /> </label></p></b> </form> </body> </html> //Servlet3.java import java.io.IOException;import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

- 24. 21 DATE: AIM: To write a html program for invoking servlet using html. ALGORITHM: STEP 1: Remove a specific attribute You can delete the value associated with a specific key by calling the public void remove Attribute(String name) function. STEP 2:Delete your whole session. To delete an entire session, use the public void invalidate() function. STEP 3:Setting Session Timeout You may set the timeout for a session separately by calling the public void set MaxInactiveInterval(int interval) function. STEP 4:Log the user out On servers that support servlets 2.4, you may use the logout method to log the client out of the Web server and invalidate all of the users’ sessions. STEP 4:web.xml Configuration If you’re using Tomcat, you may set the session timeout in the web.xml file, in addition to the ways listed above.

- 34. 31 EX.NO : 6 B DISPLAYING STUDENT MARKLIST USING JSP DATE: AIM: To create a three tier application for displaying student mark list using JSP and database. ALGORITHM: 1. Design the HTML page (stud.html) with the following a) Create a form to get the input (Register Number) from the user. b) Set the URL of the server (marklist.jsp) as the value of the action attribute. c) Use submit button to invoke the server and send the form data to the server. 2. Create the JSP file with the following a) Read the parameter value (Register Number) from the form by using the method getParameter(). b) Server retrieves the details from the database table with respect to the form input. c) Server displays the mark list to the client as the response. marklist.jsp: <%@ page contentType="text/html" language="java" import="java.sql.*"%> <html> <head> <title>Three Tier Application</title> <style type="text/css"> body{color:blue;font-family:courier;text-align:center} </style></head><body> <h2>EXAMINATION RESULT</h2><hr/> <% String str=request.getParameter("regno"); Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); Connection con=DriverManager.getConnection("jdbc:odbc:markDS"); Statement stmt=con.createStatement(); ResultSet rs=stmt.executeQuery("SELECT*FROM markTab WHERE rno="+str); while(rs.next()) { %> Register No:<%=rs.getObject(1)%><br/> Name:<%=rs.getObject(2)%><br/> <table border="1"> <th>SUBJECT</th><th>Mark</th> <tr><td>Network Programming and Management</td><td><%=rs.getObject(3)%></td></tr> <tr><td>Object Oriented Analysis and Design</td><td><%=rs.getObject(4)%></td></tr> <tr><td>Cryptography and Network Security</td><td><%=rs.getObject(5)%></td></tr> <tr><td>Embedded Systems</td><td><%=rs.getObject(6)%></td></tr> <tr><td>Web Technology</td><td><%=rs.getObject(7)%></td></tr> <tr><td>Software Requirement and Engineering</td><td><%=rs.getObject(8)%></td></tr> </table> <%} %> <br/> <a href="stud.html">Back</a> </body></html>

- 37. 34 EX.NO : 7 XML SCHEMA FOR STUDENT DETAILS DATE: AIM: To write a program for implementing student information using XML & XSL. ALGORITHM: Step1:The XML document reference to the XSL document. Step2: The create the student information in the student tag and insert the same information about the student. Step3:Close all opened tags. Step4:In XSL document create a html file include the student information in table format. Step5:Close the necessary tags.
