26.Develop an application to write a "page-composite" JSP that includes other pages or passes control to another page. (Hint: Use <jsp:include> or <jsp:forward>).
index.jsp
<html>
<head>
<title>EX-26</title>
<style>
div
{
background:#ababff;
position:absolute;
width:1000px;
left:110px;
}
.abcH
{
top:0.5cm;
width:1000px;
border-style:solid;
}
.abcL
{
top:200px;
width:1000px;
}
.abcF
{
top:500px;
width:1000px;
border-style:solid;
}
</style>
</head>
<body bgcolor="#ababff">
<%@ include file="/header.jsp" %>
<jsp:include page="/login.jsp" />
<jsp:include page="/footer.jsp" />
<br>
</div>
</body>
</html>
header.jsp
<div class="abcH" id="f1">
<br>
<table align="center">
<tr>
<td><h1>www.BipinRupadiya.blogspot.in<h1></td>
</tr>
</table>
</div>
login.jsp
<div class="abcL" id="f1">
<br>
<form method="POST" action="result.jsp">
<table align="center">
<tr>
<td colspan=2 align=center> <h3>Login</h3><hr></td>
</tr>
<tr>
<td>User Name : </td>
<td><input type="text" name="txtUsr"></td>
</tr>
<tr>
<td>Password :</td>
<td><input type="password" name="txtPwd"></td>
</tr>
<tr>
<td colspan=2 align=center><hr>
<input type="submit" value="Login">
<input type="reset" value="Reset">
</td>
</tr>
</table>
</form>
</div>
footer.jsp
<div class="abcF" id="f2">
<br>
<table align="center">
<tr>
<td><h3>© Mr. Bipin S Rupadiya<h3></td>
</tr>
</table>
</div>
result.jsp
<%
String d;
if(request.getParameter("txtUsr").equals("bipin") &&
request.getParameter("txtPwd").equals("rupadiya"))
d="welcome.jsp";
else
d="index.jsp";
%>
<jsp:forward page="<%= d%>" />
welcome.jsp

<head>
<title>EX-26</title>
<style>
div
{

</head>
<body bgcolor="#ababff">
<%@ include file="/header.jsp" %>
<div class="abcL">

<a href="index.jsp">Home</a>
</div>
<jsp:include page="/footer.jsp" />
<br>

</html>
27. You want to reduce the amount of Java coding in your JSP using a JavaBean component. (Hint: Use with the name of your bean).
Simple Interest Calculation Using Java Beans (Form Beans)
index.jsp
<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>
</head>
<body>
<div class="abc" id="f1">
<br>
<form method="POST" action="result.jsp">
<table align="center">
<tr>
<td colspan=2 align=center><h3>Simple Interest</h3><hr>
</td>
</tr>
<tr>
<td>Amount : </td>
<td><input type="text" name="p"></td>
</tr>
<tr>

<td><input type="text" name="r"></td>
</tr>
<tr>
<td>Time :</td>
<td><input type="text" name="n"></td>
</tr>
<tr>
<td colspan=2 align=center>
<hr>
<input type="submit" value="Calculate">
<input type="reset" value="Clear">
</td>

</form>
</div>

<jsp:useBean id="si" class="bsr.SimpleIntrest" />
<jsp:setProperty name="si" property="*" />
<div class="abc" id="f1">
<br>
<table width="50%" align="center">

</html>
SimpleIntrest.java
package bsr;
public class SimpleIntrest
{
private float p=1;
private float r=1;
private float n=1;
// Principal Amount
public float getP()
{
return(p);
}
public void setP(float v)
{
this.p = v;

public void setN(float v)
{

}
23. Develop a interest calculation application in which user will provide all information in HTML form and that will be processed by servlet and response will be generated back to the user.
1. Using Servlet
index.jsp
<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>
</head>
<body>
<div class="abc" id="f1">
<br>
<form method="get" action="/Ex23/bipinrupadiya.blogspot.com">
<table align="center">
<tr>
<td colspan=2 align=center><h3>Simple Interest</h3><hr>
</td>
</tr>
<tr>
<td>Amount : </td>
<td><input type="text" name="p"></td>
</tr>
<tr>
<td>Rate :</td>
<td><input type="text" name="r"></td>
</tr>
<tr>
<td>Time :</td>
<td><input type="text" name="n"></td>
</tr>
<tr>
<td colspan=2 align=center>
<hr>
<input type="submit" value="Calculate">
<input type="reset" value="Clear">
</td>
</tr>
</table>
</form>
</div>
</body>
</html>
Ex23.java
package bsr;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.WebServlet;
/** Ex23 simple Interest. by Bipin S rupadiya */
@WebServlet("/bipinrupadiya.blogspot.com")
public class Ex23 extends HttpServlet
{
public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException
{
response.setContentType("text/html");
PrintWriter out=response.getWriter();
float p=Float.parseFloat(request.getParameter("p"));
float r=Float.parseFloat(request.getParameter("r"));
float n=Float.parseFloat(request.getParameter("n"));
float i=(p*r*n)/100;
out.println("<br><h1>Simple Interest will be : "+i);
}
}
2. Using Java Beans (Form Beans)
index.jsp
<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>
</head>
<body>
<div class="abc" id="f1">
<br>
<form method="POST" action="result.jsp">
<table align="center">
<tr>
<td colspan=2 align=center><h3>Simple Interest</h3><hr>
</td>
</tr>
<tr>
<td>Amount : </td>
<td><input type="text" name="p"></td>
</tr>
<tr>
<td>Rate :</td>
<td><input type="text" name="r"></td>
</tr>
<tr>
<td>Time :</td>
<td><input type="text" name="n"></td>
</tr>
<tr>
<td colspan=2 align=center>
<hr>
<input type="submit" value="Calculate">
<input type="reset" value="Clear">
</td>
</tr>
</table>
</form>
</div>
</body>
</html>
result.jsp
<html>
<head>
<title>EX-23</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:400px;
left:5in;
border-style:solid;
}
</style>
</head>
<BODY>
<CENTER>
<jsp:useBean id="si" class="bsr.SimpleIntrest" />
<jsp:setProperty name="si" property="*" />
<div class="abc" id="f1">
<br>
<table width="50%" align="center">
<tr>
<th colspan=2><h3> Simple Interest</h3><hr></th>
</tr>
<tr>
<td>Amount : </td>
<td><jsp:getProperty name="si" property="p" /></td>
</tr>
<tr>
<td>Rate :</td>
<td><jsp:getProperty name="si" property="r" /></td>
</tr>
<tr>
<td>Time :</td>
<td><jsp:getProperty name="si" property="n" /></td>
</tr>
<tr>
<td>Interest :</td>
<td><jsp:getProperty name="si" property="intrest" /></td>
</tr>
<tr>
<th colspan=2> <hr><a href="index.jsp">Home</a></th>
</tr>
</table>
</form>
</div>
</body>
</html>
SimpleIntrest.java [ JavaBean ]
package bsr;
public class SimpleIntrest
{
private float p=1;
private float r=1;
private float n=1;
// Principal Amount
public float getP()
{
return(p);
}
public void setP(float v)
{
this.p = v;
}
// Rate of Interest
public float getR()
{
return(r);
}
public void setR(float v)
{
this.r = v;
}
// Number of Years
public float getN()
{
return(n);
}
public void setN(float v)
{
this.n = v;
}
//Calculate Interest
public float getIntrest()
{
return((p*r*n)/100);
}
}
20. Write a JSP page, which uses the include directive to show its header and footer.
index.jsp
<html>
<head>
<title>EX-20</title>
<style>
div
{
background:#ababff;
position:absolute;
width:1000px;
left:110px;
border-style:solid;
}
.abcH
{
top:0.5cm;
width:1000px;
}
.abcF
{
top:500px;
width:1000px;
}
</style>
</head>
<body>
<%@ include file="/header.jsp" %>
<jsp:include page="/footer.jsp" />
<br>
</div>
</body>
</html>
header.jsp
<div class="abcH" id="f1">
<br>
<table align="center">
<tr>
<td><h1>www.BipinRupadiya.blogspot.in<h1></td>
</tr>
</table>
</div>
footer.jsp
<div class="abcF" id="f2">
<br>
<table align="center">
<tr>
<td><h3>© Mr. Bipin S Rupadiya<h3></td>
</tr>
</table>
</div>
19. Write a simple JSP page to display a simple message (It may be a simple html page).
<html>
<head>
<title>EX-19</title>
<style>
.abc
{
background:#ababff;
position:absolute;
top:2in;
hieght:200px;
width:300px;
left:5in;
border-style:solid;
}
</style>
</head>
<body>
<div class="abc" id="f1">
<center>
<br><br>
<b>Visit</b>
<br><br>
<%
out.println("<a href='www.bipinrupadiya.blogspot.in'>www.bipinrupadiya.blogspot.in</a>");
%>
<br><br><br>
</div>
</body>
</html>
