I have the exact same problem. In a Jboss instance, the QuartzService is successfully created. Even more, existing Quartz jobs are being executed as expected.

I want to be able to access the Quartz Scheduler from a console application. However the following code prints out 'null' :

 public static void main(String[] args) throws Exception {
 InitialContext iniCtx = getInitialContext();
 Scheduler scheduler = (Scheduler)iniCtx.lookup("Quartz");

 System.out.println(String.format("Scheduler : %s", scheduler));
 }

 public static InitialContext getInitialContext() throws Exception {
 Hashtable<String, String> props = getInitialContextProperties();
 return new InitialContext(props);
 }

 private static Hashtable<String, String> getInitialContextProperties() {
 Hashtable<String, String> props = new Hashtable<String, String>();
 props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
 props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
 props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
 return props;
 }

OK, I found the answer ... the Scheduler class is not Serializable so retrieving it from outside the JBoss server hosting it will return only a null. The Quartz RMI support must be used instead.

Here is the relevant URL (read the Javadoc lines) :
