Chapter 4. Logging

Red Hat JBoss BRMS provides logback functionality for logging configuration.

Accordingly, everything configured is logged to the Simple Logging Facade for Java SLF4J, which delegates any log to Logback, Apache Commons Logging, Log4j or java.util.logging. Add a dependency to the logging adaptor for your logging framework of choice. If you are not using any logging framework yet, you can use Logback by adding this Maven dependency:

<dependency>
   <groupId>ch.qos.logback</groupId>
   <artifactId>logback-classic</artifactId>
   <version>1.x</version>
</dependency>

To configure the logging level of the packages, create a logback.xml file in business-central.war/WEB-INF/classes/logback.xml. To set the logging level of the org.drools package to "debug" for verbose logging, you would need to add the following line to the file:

<configuration>
  <logger name="org.drools" level="debug"/>

  ...
<configuration>

Similarly, you can configure logging for packages such as the following:

If configuring with log4j, the log4j.xml can be located at business-central.war/WEB-INF/classes/log4j.xml and can be configured in the following way:

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <category name="org.drools">
    <priority value="debug" />
  </category>

  ...

</log4j:configuration>
