When using the JSTL's expression language (see e1065 Enabling the JSTL Expression Language in a JSP Page), the request parameters are made available in the implicit object param. This example demonstrates how to include the value of a request parameter from the query string or posted data in the generated output:
Please enter your name.
Hello !
If the page was accessed with the URL:
http://hostname.com/mywebapp/mypage.jsp?name=John+Smith
the resulting output would be:
Hello John Smith!
