Subject Re: Strange behavior: Trying to implement saveToken() in display actions.

Doug-

Is there any reason (other than political) why you are using 1.3.8 instead
of 2.0.11+
if your concerned about implement singleton servlet context then implement
your own FilterDispatcher e.g.

public class MyFilterDispatcher extends FilterDispatcher {

public void setFilterConfig(FilterConfig filterConfig) {

//so you can achieve this objective using ServletContextSingleton class
        ServletContextSingleton singleton =
ServletContextSingleton.getInstance();
        singleton.setServletContext(filterConfig.getServletContext());
?
