I don't get any logs messages In my EventListener ... - Adobe Experience League Community

View profile · 25-04-2018

Hello guys,

I'm actually trying to get JCR events (NODE_ADDED/PROPERTY_CHANGED/PROPERTY_ADDED) from my site but I don't know if its working and I don't think so, because I'm not getting any logs written..

I created a log file thru the log support console, and I attached it on the package "com.adobe.aem.community.core.core.listeners" and "myprojectName" (which is the artifactId of my maven project, and also "apps.myapp" (myapp is the name of the site I created, It creates my logFile, I got some logs in it but not the ones I wrote in my code below..

So I created a AEM project using the archetype 12, and I have this EventListener:

                       session = null;
                   }

}

@Override
public void onEvent(EventIterator it) {

             this.LOGGER.info("### new event ###");
             System.console().writer().write("EVENT LOGGED");

while (it.hasNext()) {

Event event = it.nextEvent();
try {

                       this.writeLogFile("### LOGZZZ ###", this.session.getRootNode(), event);
                      this.LOGGER.info("### new property event: {}", event.getPath());
                       Property changedProperty = this.session.getProperty(event.getPath());
                      if (changedProperty.getName().equalsIgnoreCase("jcr:title") && !changedProperty.getString().endsWith("!")) {

                           changedProperty.setValue(changedProperty.getString() + "!");
                           this.session.save();
                       }

} catch (Exception e) {

this.LOGGER.error(e.getMessage(), e);
}

}

If anyone could help me it will be awsome

Thanks,
Hadrien
