Setting the File path for DailyRollingFileAppender
Hi all,
I was wondering if there is a way to set the 'root' directory for
destination of log files.
The 'root' for my log4j setup is C:\jakarta-tomcat-4.0.3\bin
My Log4j configuration file is attached below.
I have created a DailyRollingFileAppender and set the 'file' as:
log4j.appender.A2.File=logfile
My "appender.A2" logfile appears in the directory
C:\jakarta-tomcat-4.0.3\bin\
All is working fine - but I would like to be able to assign the 'root'
directory.
Can anyone offer advice.
My Log4j configuration file is as below:
=====================================================================
# Log4j configuration file
log4j.rootCategory=DEBUG, A1, A2
# Available levels are DEBUG, INFO, WARN, ERROR, FATAL
# A1 is a ConsoleAppender
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-5p [%t] - %m%n
# A2 is a DailyRollingFileAppender
log4j.appender.A2.File=logfile
log4j.appender.A2.DatePattern='.'yyyy-MM-dd
log4j.appender.A2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%-5p %d{ISO8601} [%t] - %m%n
log4j.appender.A2.append=true

Re: Setting the File path for DailyRollingFileAppender
Posted by Jacob Kjome <ho...@visi.com>.
Hello Michael,
I created a Log4jInit servlet that sets up system variables, uniquely
named for each webapp. The file path is stored in the system
variable. The names are predictable, so you can put it in your config
file. For instance, here is the relevant part of my lo4j.xml file:
<appender name="A2" class="org.apache.log4j.FileAppender">
<param name="File" value="${Barracuda.log.home}/main.log" />
<param name="Append" value="false" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-4r [%t] %-5p %c %x - %m%n"/>
</layout>
</appender>
The context name is "Barracuda" and all the system variables are set to
in the format of [webapp name].log.home. Adding the postfix keeps
the system variable more unique and unlikely to overwrite an existing
one.
The applicable web.xml entry looks like this:
<servlet>
<servlet-name>log4j-init</servlet-name>
<servlet-class>org.enhydra.barracuda.core.util.logging.Log4jInit</servlet-class>
<init-param>
<!-- relative path to config file within current webapp -->
<param-name>log4j-config</param-name>
<param-value>WEB-INF/log4j.xml</param-value>
</init-param>
<init-param>
<!-- config file re-reading specified in milliseconds...
Note that if the webapp is served directly from the
.war file, configureAndWatch() cannot be used because
it requires a system file path. In that case, this
param will be ignored. Set to 0 or don't specify this
param to do a normal configure(). -->
<param-name>log4j-cron</param-name>
<param-value>5000</param-value>
</init-param>
<!-- optional param for use with a File Appender.
Specifies a path to be read from a log4j xml
config file as a system property. The property name is
dynamically generated and takes on the following pattern:
[webapp name].log.home
In Barracuda's case, it would be "Barracuda.log.home".
The path defaults to WEB-INF/logs directory, which is created
if it doesn't exist, unless the webapp is running directly
from a .war file.
Note that, if specified, the value is an absolute path, not
relative to the webapp. -->
<!-- <init-param>
<param-name>log4j-log-home</param-name>
<param-value>/usr/local/logs/tomcat</param-value>
</init-param> -->
<load-on-startup>1</load-on-startup>
</servlet>
You can use this servlet by using the above configuration and
downloading Barracuda-1.1.0 and using the plankton.jar which contains the general utility classes for
the Barracuda Web Application Framework.
http://barracuda.enhydra.org/software/downloads/barracuda-1.1.0.zip
If you are looking for a web application framework, I highly recommend
Barracuda. It is not another JSP presentation project. It is kind of
like using Swing, only on the web. It uses XMLC compile pages and the
DOM to manipulate the page. Barracuda components hide the intricacies
of the DOM, but you can also use the DOM directly.
Read about it here:
http://barracuda.enhydra.org/cvs_source/Barracuda/index_details.html
Let me know if you have questions.
