You could write a DelegatingHttpSessionListenerProxy in similary way that the framework DelegatingFilterProxy.

For example (very simple and not tested)

public class DelegatingHttpSessionListenerProxy implements HttpSessionListener {
    private HttpSessionListener delegate;
    private WebApplicationContext wac;

    @Override
    public void sessionCreated(HttpSessionEvent event) {
        if (wac == null) {
            wac = findWebApplicationContext(event);
        }

        if (wac != null) {
            delegate = wac.getBean(HttpSessionListener.class);
            delegate.sessionCreated(event);
        }
    }



    @Override
    public void sessionDestroyed(HttpSessionEvent event) {
        if (wac == null) {
            wac = findWebApplicationContext(event);
        }

        if (wac != null) {
            delegate = wac.getBean(HttpSessionListener.class);
            delegate.sessionDestroyed(event);
        }
    }

    protected WebApplicationContext findWebApplicationContext(HttpSessionEvent event) {
        return WebApplicationContextUtils.getWebApplicationContext(event.getSession().getServletContext());
    }

Then, register the proxy in web.xml and manage your real implementation in the application context.
