Class JclLogger

java.lang.Object

org.apache.ignite.logger.jcl.JclLogger

All Implemented Interfaces:

IgniteLogger

public class JclLogger
extends Object
implements IgniteLogger

This logger wraps any JCL (Jakarta Commons Logging) loggers. Implementation simply delegates to underlying JCL logger. This logger should be used by loaders that have JCL-based internal logging (e.g., Websphere).

Here is an example of configuring JCL logger in Ignite configuration Spring file to work over log4j implementation. Note that we use the same configuration file as we provide by default:

      ...
      <property name="gridLogger">
          <bean class="org.apache.ignite.logger.jcl.JclLogger">
              <constructor-arg type="org.apache.commons.logging.Log">
                  <bean class="org.apache.commons.logging.impl.Log4JLogger">
                      <constructor-arg type="java.lang.String" value="config/ignite-log4j.xml"/>
                  </bean>
              </constructor-arg>
          </bean>
      </property>
      ...
 

If you are using system properties to configure JCL logger use following configuration:

      ...
      <property name="gridLogger">
          <bean class="org.apache.ignite.logger.jcl.JclLogger"/>
      </property>
      ...
 

And the same configuration if you'd like to configure Ignite in your code:

      IgniteConfiguration cfg = new IgniteConfiguration();
      ...
      IgniteLogger log = new JclLogger(new Log4JLogger("config/ignite-log4j.xml"));
      ...
      cfg.setGridLogger(log);
 

or following for the configuration by means of system properties:

      IgniteConfiguration cfg = new IgniteConfiguration();
      ...
      IgniteLogger log = new JclLogger();
      ...
      cfg.setGridLogger(log);
 

It's recommended to use Ignite logger injection instead of using/instantiating logger in your task/job code. See LoggerResource annotation about logger injection.
