How to read Standard JSR Portlet Web.xml's context-param

Question

Hi
I am completely new to Java.
I want to keep some configuration in Web.xml in Context param. My Web.xml looks like
<context-param>
<param-name>ConfigUrl</param-name>
<param-value>http://localhost:8083/</param-value>
</context-param>
How can I read these values? Can I read these values directly in my JSP file or will I have to read it in my Portlet Class in some function.
Thanks

As soon as I use portletConfig, it gives me NullPointerException. I am definitely using <portlet:defineObjects/>
My Jsp looks as :
<%@ page contentType = "text/html; charset=windows-1252"
pageEncoding = "windows-1252"
import = "javax.portlet.*, java.util.*, port.Port, port.resource.PortBundle,javax.portlet.PortletContext"%>
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet"%>
<portlet:defineObjects/>
<%
PortletContext ctx = portletConfig.getPortletContext();
String configpath = "Hello";
%>
<label>Welcome</label>
<label><%=configpath%></label>
