net.sf.taverna.raven.log
Class JavaLog

java.lang.Object
  net.sf.taverna.raven.log.JavaLog

All Implemented Interfaces:

LogInterface

public class JavaLog
extends java.lang.Object
implements LogInterface

Implementation of LogInterface for a java.util.logging backend. To use this implementation, do:

 Log.setImplementation(new JavaLog());
 

To modify java.util.logging settings and get debug messages from Raven, you can specify a system property -Djava.util.logging.config.file=blah/bluh/logging.conf and in logging.conf specify something like:

 handlers=java.util.logging.ConsoleHandler
 #.level= FINEST
 net.sf.taverna.level=FINEST
 java.util.logging.ConsoleHandler.level = FINEST
 java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
 

The default log level from Java is INFO, which for Raven means anything logged by Log.warn(), Log.error() or Log.fatal(). The mappings between LogInterface.Priority and levels of java.util.logging are:

 DEBUG --> FINER
 INFO --> FINE
 WARN --> WARNING
 ERROR --> SEVERE
 FATAL --> SEVERE
