JSP request.setAttribute Usage Guide

In JSP, you can set attribute values in a request object using the request.setAttribute(String name, Object value) method. This method takes two parameters, where the first one is the name of the attribute and the second one is the value of the attribute.

For example, the following is a straightforward example demonstrating how to use the request.setAttribute method in JSP.

<%
String name = "John";
int age = 30;

request.setAttribute("name", name);
request.setAttribute("age", age);
%>

In the example above, we set two properties in the request object: name storing the string “John” and age storing the integer 30. These values can be accessed elsewhere in the JSP page using ${requestScope.name} and ${requestScope.age}.

It is important to note that the attribute values set by the request.setAttribute method are only valid within the current request, so these values can only be accessed in the current page or in a forwarded page.
