25  * This example shows how to use LogFactor5 with other Log4J appenders
26  * (In this case the RollingFileAppender).
27  *
28  * The following lines can be added to the log4j.properties file or a
29  * standard Java properties file.
30  *
31  * # Two appenders are registered with the root of the Category tree.
32  *
33  * log4j.rootCategory=, A1, R
34  *
35  * # A1 is set to be a LF5Appender which outputs to a swing
36  * # logging console.
37  *
38  * log4j.appender.A1=org.apache.log4j.lf5.LF5Appender
39  *
40  * # R is the RollingFileAppender that outputs to a rolling log
41  * # file called rolling_log_file.log.
42  *
43  * log4j.appender.R=org.apache.log4j.RollingFileAppender
44  * log4j.appender.R.File=rolling_log_file.log
45  *
46  * log4j.appender.R.layout=org.apache.log4j.PatternLayout
47  * log4j.appender.R.layout.ConversionPattern=Date - %d{DATE}%nPriority
48  * - %p%nThread - %t%nCategory - %c%nLocation - %l%nMessage - %m%n%n
49  * log4j.appender.R.MaxFileSize=100KB
50  * log4j.appender.R.MaxBackupIndex=1
51  *
52  * To make this example work, either run the InitUsingMultipleAppenders.bat
53  * file located in the examples folder or run it at the command line. If you
54  * are running the example at the command line, you must ensure that the
55  * example.properties file is in your classpath.
