Starting camel from my own class - Camel stops when main method
stops
I want to start Camel from my own class called Startup because I want to
start other services as well.
In the Startup class I do the following:
// org.apache.camel.spring.Main
Main camelMain = new Main();
camelMain.setApplicationContextUri("../config/jms-routing.xml");
try {
camelMain.start();
} catch (Exception e) {
logger.error("Error starting camel", e);
System.exit(-1);
}
Once the main method exits camel is stopped as well:
2009-02-13 10:40:03,509 [ main] TransportConnector
INFO Connector tcp Started
2009-02-13 10:40:03,510 [ main] BrokerService
INFO ActiveMQ JMS Message Broker (localhost,
ID:semir.2e-systems.com-58933-1234518003268-0:0) started
2009-02-13 10:40:08,824 [ ActiveMQ ShutdownHook] BrokerService
INFO ActiveMQ Message Broker (localhost,
ID:semir.2e-systems.com-58933-1234518003268-0:0) is shutting down
2009-02-13 10:40:09,512 [ ActiveMQ ShutdownHook] TransportConnector
INFO Connector tcp Stopped
2009-02-13 10:40:09,578 [ ActiveMQ ShutdownHook] BrokerService
INFO ActiveMQ JMS Message Broker (localhost,
ID:semir.2e-systems.com-58933-1234518003268-0:0) stopped
If I put a thread sleep before the main method exits for 20 seconds ... then
Camel is up on 61617 for around 20 seconds.
Am I doing something wrong ?
Can anybody help ?

Hi
And maybe this page can also help setting some lower timeouts on the JMS

Hi
You can use ctrl + break or ctrl + \ on unix to dump the thread list
when you app hangs.
You can then identify what happens
We fixed an issue with the Main app not being able to stop properly,
that is fixed in Camel 1.6.0,
with a thread waiting for a countdown latch.
So try out the 1.6.0 when its released

This looks like its down to daemon threads (I can never remember
whether daemon on or off stops the JVM from terminating :).
The easiest way to fix it might be having a loop in your main asking
the user to enter 'quit' to terminate the application or something.
Either that or just wait forever via an infinite loop...
Object lock = new Object();
while (true) {
synchronized { try { lock.wait(); } catch (Exception e) { } }
}
