Description
When using in osgi (karaf), I had difficulty configuring the logging.
I used this in the Activator to get the logging core-io-deps to work.
InternalLoggerFactory.setDefaultFactory(Slf4JLoggerFactory.INSTANCE);
|
System.setProperty("log4j.configuration", "file:///Users/michaelreiche/log4j.properties"); |
log4j.properties
# Root logger option
|
log4j.rootLogger=TRACE, stdout
|
|
|
# Direct log messages to stdout
|
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
|
log4j.appender.stdout.Target=System.out
|
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
|
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
|
==========================================================================
Additions to apache karaf cong.properties :
to org.osgi.framework.bootdelegation , add :
|
|
|
javax.security.sasl, \
|
javax.security.auth.*, \
|
javax.crypto, \
|
javax.crypto.spec,
|
========================================================================== I modified LoggingEventConsumer.createLogger() to use a CONSOLE logger (that has trace and debug enabled)
Logger logger;
|
if (loggerConfig.customLogger() != null){ |
logger = loggerConfig.customLogger();
|
System.out.println("CUSTOM LOGGER: "+logger); |
}
|
else if ( false && SLF4J_AVAILABLE && !loggerConfig.disableSlf4J()){ // not this |
logger = new Slf4JLogger(name); |
System.out.println("SLF4J LOGGER: "+logger); } |
else if ( true || loggerConfig.fallbackToConsole()){ // use this |
logger = new ConsoleLogger(name); |
System.out.println("CONSOLE LOGGER: "+logger); } |
else { |
logger = new JdkLogger(name); |
System.out.println("JDK LOGGER: "+logger); |
}
