Michael Baessler commented on UIMA-282:
---------------------------------------
I'm not sure that I understand all what you are saying...
Do you mean that we should use a commonLogging_impl class that implements the
org.apache.uima.util.Logger interface and use internally the commons logging
toolkit. For example LogFactory.getLog() to get a logger?
So when doing this we don't need to have all the logging dependencies in place
except of commons-logging.jar and the logging framework can be configured using
the commons logging configuration.
What I currently do not understand is, what do you mean by "add it to the pom
filtering all real implementation dependencies..." ??
I think we have to update the factoryConfig.xml file that the commons logging
is used.

> UIMA uses the standard java.util.logging (JUL). Most of my company's code
> used Apache Log4J, so we have a problem merging the messages from the two
> logging packages. Given that UIMA is now an Apache project, I think it makes
> sense that it work with Apache logging.
> Two options occur to me:
> 1. Change all the logging calls in the code (perhaps Eclipse refactoring
> tools can help with that). Here's some discussion on migrating:
> http://www.oreillynet.com/onjava/blog/2005/12/migrating_from_jdk_logging_to.html
>
> You could convert either to Log4J ( http://logging.apache.org/log4j/docs ) or
> to Apache Jakarta Commons Logging ( http://jakarta.apache.org/commons/logging
> ), which would allow UIMA to be configured to use either JUL or Log4J.
> 2. Write/find a JUL Handler that re-directs to Log4J. Here's an example:
