Hi
I have created two listeners with eventType ‘NODE_ADDED’ for “dms” &
“website” section of Author Instance respectively following the observation
module example of magnolia documentation.
First listener’s job is to execute a command to activate the content to Public
instance when we upload a new file under “downloads” of “demo-projects” folder.
The second listener’s job is to output a message to console when a new page is
added under “demo-projects” of website
section.[img]C:\Users\m1009523\Desktop\listener.png[/img][u][b]

import javax.jcr.observation.EventListener;
/**
* basic example that prints a message to the console
* @author tmiyar

*/
public class PageListener implements EventListener {
public void onEvent(EventIterator events) {
System.out.println("EventListener Test: Text Message");
Event event;
while(events.hasNext()){
event = (Event) events.nextEvent();
// depends of the type of event
Content node;
try {
// node = new
SystemRepositoryStrategy((SystemContext)MgnlContext.getSystemContext()).getHierarchyManager("website",
"website").getContent(event.getPath());
node =
LifeTimeJCRSessionUtil.getHierarchyManager("website").getContent(event.getPath());
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println("EventListener Test: Text Message2");
}
}
I have kept the .class file of PageListener class under
[b]
C:\Program
Files\MagnoliaEnterpriseEdition\apache-tomcat-6.0.32\webapps\magnoliaAuthor\WEB-INF\classes[/b]
I tested & found both of these listeners are not working. In the console I
found no message output. If anyone is having any clue to proceed will be of
great help for me. Need to get a clear picture how it works.
I am getting the following error in console when trying to activate the
observation module in author instance.Is it required necessarily ??
