public class FileHandler extends Handler
The following configuration properties are available:
directory - The directory where to create the log file.
If the path is not absolute, it is relative to the current working
directory of the application. The Apache Tomcat configuration files usually
specify an absolute path for this property,
${catalina.base}/logs
Default value: logsrotatable - If true, the log file will be
rotated on the first write past midnight and the filename will be
{prefix}{date}{suffix}, where date is yyyy-MM-dd. If false,
the file will not be rotated and the filename will be {prefix}{suffix}.
Default value: trueprefix - The leading part of the log file name.
Default value: juli.suffix - The trailing part of the log file name. Default value: .logbufferSize - Configures buffering. The value of 0
uses system default buffering (typically an 8K buffer will be used). A
value of <0 forces a writer flush upon each log write. A
value >0 uses a BufferedOutputStream with the defined
value but note that the system default buffering will also be
applied. Default value: -1encoding - Character set used by the log file. Default value:
empty string, which means to use the system default character set.level - The level threshold for this Handler. See the
java.util.logging.Level class for the possible levels.
Default value: ALLfilter - The java.util.logging.Filter
implementation class name for this Handler. Default value: unsetformatter - The java.util.logging.Formatter
implementation class name for this Handler. Default value:
