The simplest way is to use a context parameter in your web.xml file:

  <context-param>
    <param-name>global-name</param-name>
    <param-value>This is the parameter value</param-value>
  </context-param>

which you can retrieve from a servlet by calling:

  getServletContext().getInitParameter("global-name");

NOTE:  There are rules you *must* follow about the order of elements in
your web.xml file -- see the Servlet Specification, which you can download
from:
