Adding multiple paths in event listener

[P_V_Nair]

I have an event listener in which I am listening to a path as in the below screenshot using Observation Manger . How can I add multiple paths here , so that I can listen to multiple paths. I cannot add the root path, since I don't want to listen to the root path due to other project requirement constraints.

Hi @P_V_Nair ,

Try using ResourceChangeListener to handle multiple paths.

As @Kishore_Kumar_ already pointed out, use the ResourceChangeListener.

if that's not possible: 

JackrabbitObservationManager mgr = (JackrabbitObservationManager) session.getWorkspace().getObservationManager;

JackrabbitEventFilter filter = new JackrabbitEventFilter()
  .setAbsPath(PATH1)
  .setAdditionalPaths(PATH2,PATH3, ...)
...

mgr.addEventListener(listener, filter);

This allows to you specify more constraints than the JCR compliant JCR ObservationManager. In Oak the ObservationManager implements the JackrabbitObservationManager.
