1. Include an ApplicationLog4jConfigurationGBean in your application plan, like this:

   Code Block
   <gbean name="DirectoryLog4jConfiguration" class="org.apache.geronimo.system.logging.log4j.ApplicationLog4jConfigurationGBean"> <attribute name="log4jFile">var/directory/log4j.properties</attribute> <reference name="ServerInfo"><name>ServerInfo</name></reference> </gbean>

   You can also use a log4j.properties file in your classpath, but this will obstruct anyone trying to configure logging as the file will remain packed in your application somewhere hard to find:

   Code Block
   <gbean name="DirectoryLog4jConfiguration" class="org.apache.geronimo.system.logging.log4j.ApplicationLog4jConfigurationGBean"> <attribute name="log4jResource">META-INF/log4j.properties</attribute> </gbean>

2. Include the log4j.properties configuration file in an appropriate location in your plugin, say META-INF/log4j.properties
3. Unpack the log4j.properties file during plugin installation by including something like this in the pom.xml that generates geronimo-plugin.xml:

   Code Block
   <plugin> <groupId>org.apache.geronimo.buildsupport</groupId> <artifactId>car-maven-plugin</artifactId> ... <instance> <plugin-artifact> <copy-file relative-to="server" dest-dir="var/directory">META-INF/log4j.properties</copy-file> ... </plugin-artifact> </instance> </configuration> </plugin>

4. Configure application specific logging in your log4j.properties file. The gbean prevents you from overriding settings that apply to global logging, but you can configure appenders for specific loggers for your application. Here's the example for ApacheDS:

   Code Block

   #attach an appender to the base apacheds package logger: log4j.logger.org.apache.directory=INFO,apacheds #do not log apacheds to geronimo logs: log4j.additivity.org.apache.directory=false #Configure the apacheds specific appender: log4j.appender.apacheds=org.apache.log4j.DailyRollingFileAppender log4j.appender.apacheds.File=${org.apache.geronimo.server.dir}/var/log/apacheds.log log4j.appender.apacheds.layout=org.apache.log4j.PatternLayout # geronimo style logging log4j.appender.apacheds.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n # some settings for the apacheds loggers, taken from the standard apacheds log4j.properties file. # with these we'll not get innundated when switching to DEBUG log4j.logger.org.apache.directory.shared.ldap.name=WARN #log4j.logger.org.springframework=WARN log4j.logger.org.apache.directory.shared.codec=WARN log4j.logger.org.apache.directory.shared.asn1=WARN
