What is the equivalent of HttpServletRequest.getServletContext() in old version of java?

Question

My project is using some very old code and I can't really update it. There are some values that I would like to access in WEB-IN/web.xml/context-param. In recent version of java you could use :

HttpServletRequest servlet;
...
String myParam = servlet.getServletContext().getInitParameter("myParam");

But the method getServletContext() doesn't exist in my project configuration.

Is there another way to gain access to the WEB-INF/web.xml/context-param for old version of java/tomcat?
