I have used Camel a few times now but this problem is over my head and I have no clue what I'm doing wrong. It is a new application that should fetch messages from IBM MQ and place files to disk. The route is very simple:
String fromString = "message-queue:XXX.FUNDORDER.YYY.OUT?testConnectionOnStartup=true";
from(fromString)
.autoStartup(true)
.routeId("RouteReceiver")
.log("Processing message ${exchangeId}")
.to("file:/in?fileName=${exchangeId}.txt");
Here's the code used when creating the Connection factory:
public JmsConnectionFactory websphereConnectionFactory() throws JMSException
{
Logger logger = Logger.getLogger(Config.class);
logger.info("ibmMqChannel = " + ibmMqChannel);
logger.info("ibmMqHost = " + ibmMqHost);
logger.info("ibmMqPort = " + ibmMqPort);
logger.info("ibmMqQueueManagerName = " + ibmMqQueueManagerName);
/*
* Create MQConnectionFactory
*/
final MQConnectionFactory connectionFactory = new MQConnectionFactory();
connectionFactory.setHostName(ibmMqHost);
connectionFactory.setPort(ibmMqPort);
connectionFactory.setChannel(ibmMqChannel);
connectionFactory.setQueueManager(ibmMqQueueManagerName);
connectionFactory.setIntProperty(CommonConstants.WMQ_CONNECTION_MODE, CommonConstants.WMQ_CM_CLIENT);
logger.debug("connectionFactory=" + connectionFactory.toString());
/*
* Add ConnectionFactory to JmsConfiguration
*/
final JmsConfiguration jmsConfiguration = new JmsConfiguration();
jmsConfiguration.setConnectionFactory(connectionFactory);
/*
* Add JmsConfiguration to JmsComponent
*/
final JmsComponent jmsComponent = new JmsComponent();
jmsComponent.setConfiguration(jmsConfiguration);
jmsComponent.setAcknowledgementModeName("AUTO_ACKNOWLEDGE");
/*
* Add JmsComponent to camelContext
*/
camelContext.addComponent("message-queue", jmsComponent);
return connectionFactory;
}
Right after the application is started and connection is tested it immediately starts shutting down. No exceptions are thrown. When testing locally I'm using a different profile and connects to an ActiveMQ server instead. This runs fine and does what it is supposed to.
Any help would be greatly appreciated!

Are you using SpringBoot? If yes, is it possible that your application does not block and therefore simply shuts down after startup because the main method is done?
According to http://camel.apache.org/spring-boot.html there are many ways to block the main thread in a SpringBoot application (see Link for further details):
org.apache.camel.spring.boot.FatJarRouter class CamelSpringBootApplicationController.blockMainThread() spring-boot-starter-web dependency in pom.xmlcamel.springboot.main-run-controller to true in property or YAML file
