This post is from http://www.roseindia.net/jsp/SetAttributeMethod.shtml

 

This method sets the value of the attribute for the request which is retrieved later either in the current JSP page or the another JSP page by passing the request object through the dispatcher method. The set value of the attribute is retrieved by the getAttribute(String) method of the request object.

 

Here is the JSP code of the SetAttributeMethod.jsp file

<%
        request.setAttribute("AttributeName","This is the Attribute value.");
        String strViewPage="SetAttributeMethod1.jsp";
        RequestDispatcher dispatcher = request.getRequestDispatcher(strViewPage);
        if (dispatcher != null){
                dispatcher.forward(request, response);
        }
%>

 

Here is the JSP code of the SetAttributeMethod1.jsp file

<%
        out.println(request.getAttribute("AttributeName"));
%>
