No Jobs Found

[jetnet]

a silly question - does JEF monitor work on Windows? I'm asking, because I'm getting the "no jobs found" message, when I point JEF to the crawler's progress\latest directory, which is containing one "<httpcollector_id>.index" file.

Not sure, if the following is related, but JEF (4.0.5) is throwing an exception when started:

Exception in thread "Thread-10" com.norconex.commons.lang.config.ConfigurationException: This class could not be instantiated: "com.norconex.jef4.log.NoLogManager".

Yes it does. JEF uses the log manager defined in your collector to offer the ability to view logs.

In your case, you are using the snapshot version that has com.norconex.jef4.log.NoLogManager. That class is not found in JEF Monitor class path. So the solution is to replace the norconex-jef.jar found in JEF Monitor lib directory with the snapshot version of JEF API.

Thanks, Pascal! upgrading to norconex-jef-4.1.2-20190419.210227-1.jar helped - no exception and the job is displayed now!

FYI: I was using a version from https://www.norconex.com/jef/monitor/ - it was not marked as a snapshot one. Maybe the link is not correct.

Thanks for reporting this. There is now a snapshot version of JEF Monitor that is in sync with the JEF API snapshot.
