[jemminger]

i'm sure this is simple, but i can't seem to find the answer...

Hi Jeff,

There is no <config-param> element in the web.xml dtd, but I'm guessing you mean <context-param>, ie :

<context-param>
<param-name>hello</param-name>
<param-value>qqq</param-value>
</context-param>


In any case, to get this value :

String hello = this.getServletConfig().getServletContext().getInitParameter("hello");

but that is really only accessible from an object that extends HttpServlet.

You could also do :

String hello = request.getSession().getServletContext().getInitParameter("hello");

where request is a HttpServletRequest object.

In effect, you will either have to :
- set these values in your servlet / JSP, and pass them to the relevant bean, or
- add them into a HttpSession object to be retrieved by the bean, or
- pass a HttpServletRequest object to the bean (bit messy).
