I have the following Timer service class defined:
| @Stateless
| @RemoteBinding(jndiBinding="XXXCommandRemote")
| public class XXXCommandBean implements XXXCommandRemote
| {
| static Logger logger = Logger.getLogger(XXXCommandBean.class);
|
| @Resource TimerService timerService;
|
| public void scheduleCommand(Command command)
| {
| timerService.createTimer(command.getDuration(), command);
| }
|
| public void scheduleContinousCommand(Command command)
| {
| timerService.createTimer(command.getDuration(),
command.getDuration(), command);
| }
|
| @Timeout
| public void runCommand(Timer timer)
| {
| Command command = (Command) timer.getInfo();
|
| logger.debug("runCommand: Firing command for user: " +
command.getUserId() + " " + command.getDescription());
|
| User user = null;
|
| System.setProperty("java.security.policy", "server.policy");
| if (System.getSecurityManager() == null)
| {
| System.setSecurityManager(new RMISecurityManager());
| }
|
| InitialContext jndiContext;
| try
| {
| jndiContext = getInitialContext();
| UserRemote playerRef = (UserRemote)
jndiContext.lookup("UserRemote");
| USerRemote dao = (UserRemote)
PortableRemoteObject.narrow(playerRef, UserRemote.class);
| user = dao.findUser(command.getUserId());
| }
| catch (NamingException e)
| {
| logger.error("NamingException: ", e);
| }
| ...
|
This seems to work fine in normal cases.
However, if I have a command scheduled for the future, and then restart the app
server I get the following error when the Timeout hook runs:

This is happening during lookup:
UserRemote playerRef = (UserRemote)jndiContext.lookup("UserRemote");
