exceptions and log levels
Hi!
I've written a CollectionReader implementation that can throw an Exception in
the getNext() method. I've only configured the java.util.logging root logger to
use a ConsoleHandler with Level.ALL. Without touching the log configuration of
the UIMA packages, any Exception thrown in the CollectionReader.getNext() is
just swallowed when running the CPE. Looking at the code (in particular the
ArtifactProducer.readNext() method which calls CollectionReader.getNext()), it
seems that I have to set the log level FINER at the UIMAFramework
("org.apache.uima") logger to see the exceptions. But then I also see all other
sorts of debug traces, e.g. begin and end of processing of an AE. Is this really
intended?
Thanks in advance!
Peter

Awesome! Thank you very much!

Thanks, this works like a charm.
Cheers,

Peter, I don't recall a specific reason why Exceptions caught in
ArtifactProducts.run()
method are only logged at Level.FINER. This seems wrong to me. I remember
putting
conditionals around all logging though. Perhaps this was a cut and paste
mistake. I'll
add JIRA to fix this.
If you want to handle exceptions coming from your CR, just plugin a
callback listener
to the CPM. This listener will be called on an exception and you'll get a
call back.
