How do I get a HttpServletRequest object when loading a JSP page?

java, jsp, servlets

Solution

Just use the `request` variable (`HttpServletRequest` instance). It is one of implicit objects in JSP. Check properties here: http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletRequest.html

<%
    request.getHeader();
%>

Problem

I have a HTML page that allows me to use JSP code. I was able to print some output using some basic Java. But How do I obtain a HttpServletRequest object so I can print some of its properties onto the HTML page?
