event.getServletContext() returning Null in a ServletContextListener

[Jason Soper]

Hi Guys,

I have a ServletContextListener set up to add an ELResolver to the resolver chain. The listener looks a bit like this:

public class EscapeXmlELResolverListener implements ServletContextListener {
	public void contextInitialized(ServletContextEvent event) {
		ServletContext context = event.getServletContext();
		JspFactory jspFactory = JspFactory.getDefaultFactory();
		JspApplicationContext jspApplicationContext = jspFactory.getJspApplicationContext(context);
		ELResolver elResolver = new EscapeXmlResolver();
		jspApplicationContext.addELResolver(elResolver);
	}
}

I have the listener registered in the web.xml like this:

<listener> <listener-class>net.scee.extranet.lossprevention.listeners.EscapeXmlELResolverListener</listener-class> </listener>

This is all working fine on my local machine. The code is running wirhout error and the ELResolver is being added and functioning correctly.

My problem is when I run the code on our test server. I'm not sure what's different, but in that environment it falls over when it tries to use context. As far as I can tell, event.getServletContext() is returning null.

Can anyone suggest what might be causing this? Or is there another way of doing this? This is a Spring application, if that makes any difference.

Thanks,

Jason
