Well, thanks for the helpful advice thus far..
So, now that I've added a listener properly, I get this:
java.lang.UnsupportedOperationException: Section 4.4 of the Servlet
3.0 specification does not permit this method to be called from a
ServletContextListener that was not defined in web.xml, a
web-fragment.xml file nor annotated with @WebListener
at
org.apache.catalina.core.StandardContext$NoPluggabilityServletContext.addListener(StandardContext.java:7019)
When I try adding my listener...
@WebListener
public class CdiServletContextListener implements ServletContextListener
{
@Override
public void contextInitialized(ServletContextEvent servletContextEvent)
{
servletContextEvent.getServletContext().addListener(new
CdiCtrlListener());
}
I even tried rigging my class to have WebListener on it.. until I
noticed the method just threw an exception... no questions asked. :-)
