Using getInitParameter in Java application with JSP pages

I have a web application, which has previously used solely JSP pages and accessed properties in the web.xml file using:
getServletContext().getInitParameter("property_name");

I have since added some Java classes to this application to do various bits and pieces of work, and I am not sure how to access the same information from the web.xml file?

Can someone please advise (or provide a code snippet) as to how to access this information from a java class?

PAss through a reference to your ServletContext to the Java classes that need to access this information.

I am using Netbeans to develop this project, are you saying that I should pass through like so,..?

                                 
                                ServletContext sContext = ServletContext.getServletContext();
                                  Emailer email1 = new Emailer(sContext);

and then it should work (I'm not at work so I cannot test it yet)

you could do that, or just pass the parameter(s) it needs

   ServletContext sContext = ServletContext.getServletContext();
   Emailer email1 = new Emailer(sContext.getInitParameter("property1"), sContext.getInitParameter("property2"));
