Method Detail

createLogger

public static org.apache.commons.logging.Log createLogger(java.lang.Class<?> logName)

Set the TCCL of the bundle before creating the logger. This helps if commons-logging is used since it looks at the existing TCCL before associating a LogFactory with it and since the TCCL can be the BundleDelegatingClassLoader, loading a LogFactory using the BundleDelegatingClassLoader will result in an infinite cycle or chained failures that would be swallowed.

Create the logger using LogFactory but use a simple implementation if something goes wrong.

Parameters:

logName - log name

Returns:

logger implementation

doCreateLogger

private static org.apache.commons.logging.Log doCreateLogger(java.lang.Class<?> logName)
