JSTL: Property Access

                          

In this example we are going to show we can access the property by using  the dot(.) and [ ] operator. 

Firstly we are going to make a form where we will enter some values and those values will be shown to you. The value will be shown to you in the following way. Firstly we will set the values which we have retrieved from the  form in the attribute var. After setting the values the output will be displayed to you by using the <c:out> tag. 

The code of the program is given below:

 

 

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<html>
<head>
<title>Property Access</title>
</head>

<body>
<form method="post">Enter your name :
<input type="text" name="name" /><br><br>
Enter your password : <input type = "password" name = "password"/><br>
<input type="Submit" />

<br />
</form>

<c:if test="${pageContext.request.method=='POST'}">
<c:set var="username" value="name" /><br>
<c:set var ="userpwd" value ="password"/><br>
param.name = <c:out value="${param.name}" /><br>
param.password = <c:out value = "${param.password}"/><br>

param[name] = <c:out value="${param[username]}" /><br>
param[password] = <c:out value="${param[userpwd]}"/>
</c:if> 
</body>
</html>

The output of the program is given below:
