OSGi Log Service
Corona Logging uses OSGi Log Service. OSGi specifies two log services:
- Log Service - allows bundles to log information including a message, a level, an exception, a ServiceReference object, and a Bundle object
- Log Reader Service - allows bundles to access a list of LogEntry objects, and allows the registration of a LogListener object that receives LogEntry objects as they are created.
To extend control over log statements log4j package is used. It is plugged into Corona through the LogListener object registered with the use of the OSGi Log Reader Service.
For details on OSGi services see: OSGi Service Platform, Service Compendium, Release4, August 2005.
