I am using eclipse osgi jar. How to redirect the log generated by osgi to a file?
Whenever I start the osgi framework, it generates a log like 1317008078357.log. How to redirect this log to a custom file. Do I need to use log4j as a osgi bundle? what will be the log4j.xml configuration ?
log file contains:
!SESSION 2011-09-26 11:34:38.232 -----------------------------------------------
eclipse.buildId=unknown
java.version=1.6.0_26
java.vendor=Sun Microsystems Inc.

Usually Logback is configured by a logback.xml or logback-test.xml file. (see Logback configuration manual) In an OSGi environment it is not that easy for Logback to automatically determine where the logback.xml logger configuration is stored.
By default Eclipse logs all messages. In case dependency injection is not available in the class where logging is requested, the logger can be obtained by using the service API: 2. SLF4J in eclipse applications Many Java developers are more familiar with the SLF4J logging facade, which is more powerful than Eclipse’s default logger. 2.1.
open the “console” view. select the “host osgi console.” start org.eclipse.equinox.cm start org.ops4j.pax.logging.pax-logging-api start org.ops4j.pax.logging.pax-logging-service start org.ops4j.pax.configmanager now you should be able to see your log statements in the configured “example.log” file.
The value can be set to INFO, WARNING and ERROR, INFO will for example show all log message. By default Eclipse logs all messages. In case dependency injection is not available in the class where logging is requested, the logger can be obtained by using the service API:
Eclipse (Equinox) uses his own logger. To configure it you can define the logger options in config.ini:
osgi.logfile file name
eclipse.log.level sets the level used when logging messages to the eclipse log.
eclipse.log.backup.max the max number of backup log files to allow.
eclipse.log.size.max the max size in Kb that the log file is allowed to grow.
