Logging uima in Tomcat application

[swirl <sw...@yahoo.com>]

Hi,

I am running uima inside a maven tomcat application, but I could not figure 
out how to capture the logs generated by the uima analysis engines and 
collection readers.
What is the configuration in tomcat that will let me specify the location of 
the uima logs to be stored?

I tried putting logging.properties in the WEB-INF/classes folder but it seems 
to be ignored.

Hi,

the logging mechanism and its configuration is described here [1]. UIMA 
uses the Java Util logging API [2] by default. 

As documented in [1], you can change the logging mechanism used
by UIMA by specifying an alternative backend implementation, e.g.:

-Dorg.apache.uima.logger.class=org.apache.uima.util.impl.Log4jLogger_impl

Alternatively, you could install a  custom JUL handler and redirect the
logging output to whatever you are using. This is what e.g. the
jul-to-slf4j brigde [3] does.
