request.setAttribute() is a method used in Java Servlets to set an attribute in the request object. This attribute can then be accessed by the JSP or servlet that processes the request.
Syntax:
request.setAttribute(String name, Object value)
Parameters:
- name: A String representing the name of the attribute.
- value: An Object representing the value of the attribute.
Example:
In a servlet, you can set an attribute in the request object as follows:
request.setAttribute("message", "Hello World!");
In a JSP, you can access this attribute using the following code:
<% String message = (String) request.getAttribute("message"); %>
The above code retrieves the value of the "message" attribute from the request object and stores it in a String variable called "message".
