Logging with Log4j

BeanConnect uses the software product Log4j for logging functionality. Log4j is part of the Apache Jakarta project. Log4j offers interfaces for logging information (runtime information, trace records, etc.) and for configuring log output.

Log4j uses configuration files written in XML. The names of these files are fixed. All BeanConnect components using Log4j are delivered with preconfigured configuration files.The names of the output files are predefined in the configuration files. Different BeanConnect components use different names for their output files.

This section provides information on the following topics:

• Basic principles of Log4j

• Loggers

• Appenders

• How the rolling file appender works
