Reading Request Attributes Using JSTL
Reading Request Attributes Using JSTL explains about how to access JSTL's request scoped attributes such as variables inside a JSP page
request is an implicit object available in JSP, so it is very easy to access the request scoped varaibles inside JSP page
You can access the request scoped varaibles in following different ways
<c:out value='${requestScope["variableName"]}'/>
<c:out value='${requestScope.variableName}'/>
you can see the below example demonstrating how to access request scoped attributes in JSTL EL expression
