Hi,
I'm trying to create a simple event listener, but it's having troubles
finding the eventSubscriptionService bean. My component-dao.xml file looks
like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:tx="http://www.springframework.org/schema/tx";
xmlns:context="http://www.springframework.org/schema/context";
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd";
>
<context:annotation-config/>
<bean name="JmsQueueEventListener"
class="org.neoninc.opennms.JmsQueueEventListener" />
<bean id="JmsQueueEventListenerAdapter"
class="org.opennms.netmgt.model.events.AnnotationBasedEventListenerAdapter">
<property name="annotatedListener" ref="JmsQueueEventListener" />
<property name="eventSubscriptionService" ref="eventSubscriptionService"
/>
</bean>
</beans>
When it tries to create the JmsQueueEventListenerAdapter, it fails to
resolve the reference to the bean 'eventSubscriptionService'. I get the
following stack trace:
An error occurred while attempting to start the "OpenNMS:Name=Eventd"
service (class org.opennms.netmgt.eventd.jmx.Eventd). Shutting down and
exiting.

The Java class itself is very simple:
package org.neoninc.opennms;
import org.opennms.netmgt.EventConstants;
import org.opennms.netmgt.model.events.annotations.EventHandler;
import org.opennms.netmgt.model.events.annotations.EventListener;
import org.opennms.netmgt.xml.event.Event;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@EventListener(name="neon:JmsQueueEventListener")
public class JmsQueueEventListener {
Logger logger = LoggerFactory.getLogger(JmsQueueEventListener.class);
@EventHandler(uei=EventConstants.NODE_DOWN_EVENT_UEI)
public void onEvent(Event event) {
logger.debug("Handling onEvent om EventListener!!!");
logger.debug(event.getDescr());
}
}
Any ideas where I'm going wrong?
Thanks,
DJ Spiess
