Class GridJclLogger

java.lang.Object
  org.gridgain.grid.logger.jcl.GridJclLogger

All Implemented Interfaces:

GridLogger

public class GridJclLogger
extends Object
implements GridLogger

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 GridGain 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.gridgain.grid.logger.jcl.GridJclLogger">
              <constructor-arg type="org.apache.commons.logging.Log">
                  <bean class="org.apache.commons.logging.impl.Log4JLogger">
                      <constructor-arg type="java.lang.String" value="config/default-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.gridgain.grid.logger.jcl.GridJclLogger"/>
      </property>
      ...
 

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

      GridConfiguration cfg = new GridConfigurationAdapter();
      ...
      GridLogger log = new GridJclLogger(new Log4JLogger("config/default-log4j.xml"));
      ...
      cfg.setGridLogger(log);
 

or following for the configuration by means of system properties:

      GridConfiguration cfg = new GridConfigurationAdapter();
      ...
      GridLogger log = new GridJclLogger();
      ...
      cfg.setGridLogger(log);
 

Please take a look at GridLoggerResource annotation about logger injection.
