Logback Support
You can use the Configurator to configure Logback through an XML configuration file:
<bean name="org.apache.cocoon.spring.configurator.logback"
class="org.apache.cocoon.spring.configurator.logback.LogbackConfigurator"
scope="singleton">
<property name="resource" value="/WEB-INF/cocoon/logback.xml"/>
</bean>
The property resource should point to a valid Logback XML configuration file. You can use all properties configured through the Configurator in the XML configuration and reference the actual values.
