Subject Problem with stopping route. camelContext.stopRoute(String routeId); throws java.lang.NullPointerException
Date Tue, 08 Oct 2013 15:08:09 GMT
*What's my error???
Why do I get the java.lang.NullPointerException ???*

*I am using this function to terminate a route that is run by a different
thread than the main one that calls this function:*

private void terminate(String routeId, int index) {
        try {
        	System.out.println("%%%%%%%%% camelContext.stopRoute(" + routeId +
");" + " :: THREAD: " + Thread.currentThread().getId());
	        camelContext.stopRoute(routeId);
		camelContext.removeRoute(routeId);
		thread_id.get(index).join();
	} catch (Exception e) {
		System.out.println("%%%%%%%%% EXCEPTION in terminate()" + " :: THREAD: " +
Thread.currentThread().getId());
		e.printStackTrace();
	}
}


*Route is running here:*

$$$$$$$$$ Receiver :: account_id: 7 ::
smpp://8000800666@123.123.123.123:1111?password=123456 :: *THREAD: 579
*


karaf@root> route-list
Route Id             Context Name         Status
[retrievingAccounts] [ReceivingContext  ] [Started           ]
[*receiving:8000800666*] [ReceivingContext  ] [Started           ]


*Then I call terminate(receiving:8000800666); but I get this exception:
java:174 is camelContext.stopRoute(routeId); from the terminate function
above*


%%%%%%%%% camelContext.stopRoute(*receiving:8000800666*); :: *THREAD: 573*
%%%%%%%%% EXCEPTION in terminate() :: THREAD: 573
java.lang.NullPointerException
