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