             Summary: Webapp's ENC destroyed before ServletContextListener invoked
                 Key: AS7-5746
                 URL: https://issues.jboss.org/browse/AS7-5746
             Project: Application Server 7
          Issue Type: Bug
          Components: Naming, Web
    Affects Versions: 7.1.1.Final
            Reporter: Philippe Marschall
            Assignee: Eduardo Martins


It looks as if when {{javax.servlet.ServletContextListener#contextDestroyed(ServletContextEvent)}} is invoked the naming service / context has already been shut down. 

Consider the following class
{code}
public class BindingListener implements ServletContextListener {
	
	private static final Logger LOG = Logger.getLogger("binding-listener");
	private static final String NAME = "java:global/env/foo";
	private static final String VALUE = "FOO";

	@Override
	public void contextInitialized(ServletContextEvent sce) {
		LOG.info("contextInitialized");
		try {
			Context context = new InitialContext();
			context.rebind(NAME, VALUE);
		} catch (NamingException e) {
			LOG.log(Level.SEVERE, "could not bind value", e);
		}
		
	}

	@Override
	public void contextDestroyed(ServletContextEvent sce) {
		LOG.info("contextDestroyed");
		try {
			Context context = new InitialContext();
			context.unbind(NAME);
		} catch (NamingException e) {
			LOG.log(Level.SEVERE, "could not unbind value", e);
		}
	}

}
{code}

This results in the following exception when shutting down the container.

This seems to be a reappearance of JBAS-672.

I would provide a patch/pull request if somebody can point me in the right direction.
