Application Log Output
An application log is always included in the set of files saved to a transaction archive. However, you can specify an additional location for sending application log messages:
com.arbortext.e3.applicationLog.display
By default, explicitly set to false to log messages to the transaction archive.
If set to true, application log messages are also written to the Arbortext Diagnostics window. See Getting Trace Information for more information.
com.arbortext.e3.applicationLog.displayPatternLayout
Specifies the Java log4j pattern to use when constructing log entries to standard output or the Arbortext Diagnostics window. The com.arbortext.e3.applicationLog.display must also be set to true.
The default is set to :
%d{HH:mm:ss} [%t] %-5p %c{2} - %m
Refer to the log4j documentation for an explanation of the pattern.
