JSTL out tag

JSTL out tag is used to display information on JSP. It can also be used with properties of the bean.

JSTL c out tag Example:

To display the name of the product on JSP, you can use the <c:out> tag like:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>JSTL c out Tag example</title>
</head>
<body>
  <c:out value="${product.name}" default="Not Available" escapeXml="true"></c:out>
</body>
</html>

The above statement assumes that product object is available on this JSP and that product bean has a property name with setters and getters.

Attributes of <c:out> tag are:

Required Attributes:

1. value:This attribute needs expression to be evaluated.

Optional Attributes:

1. default: This attribute provides default value if the resulting value is null.

2. escapeXml: This attribute determines whether characters &,'," in the resulting string should be converted to their corresponding character entity codes. Default value is set to true.
