The content pipeline uses Apache log4j Ver 1.13 (http://jakarta.apache.org/log4j/docs/) as its error logging mechanism. The Log4jErrorHandler is the default message reporting class. Messages generated by individual filters can be reported by calling log4j methods or using calls to the error handler embedded in every filter.

The logj4 logging mechanism specifies the amount of information logged (verbosity), destination (file, console, or screen), and format (for example, plain text or xml). The only parameters to specify in the filter for error logging are message content and severity levels.

You can control attributes of the Event Log by calling the composer_log ACL function. Refer to the Arbortext Editor online help for detailed information on the composer_log function.
