Substitute AuditLog entries

Hi everyone,

I am currently working with AEM 6.1 SP2. What I want to achieve is the substitution/extension of the system PageEventAuditListener.

For that reason I write my own PageEventAuditHandler. It should listen just for PageEvents. However I do not know how to connect my service to the current AuditLog, so that I could write my own AuditLogEntries to it.

I appreciate every hint/tip to solve that issue.

Output of error.log:

18.10.2016 10:30:05.463 *ERROR* [pool-11-thread-3-null(null)] org.apache.sling.event.jobs.JobUtil Unhandled error occured in job processor null while processing job org.osgi.service.event.Event [topic=com/day/cq/wcm/core/page]

        at java.lang.Thread.run(Thread.java:745)

To speed up things I attached the source code of my service.

Thanks for your help in advance.

Best regards,

Marcus
