Log4J and eclipse

sometimes you want to use the log4j system instead of the internal eclipse provide logging framework.

The use of this is rather simple and straight forwarded. You only need to register an ILogListener at the platform object and implement it.

An example would be:


package edu.ucdavis.genomics.metabolomics.binbase.gui.swt.logging;

import org.apache.log4j.Logger;
import org.eclipse.core.runtime.ILogListener;
import org.eclipse.core.runtime.IStatus;

/**
* used to forward eclipse logging to log4j
*
* @author wohlgemuth
*
*/
public class Log4JListener implements ILogListener {

static Logger LOGGER = Logger.getLogger(Log4JListener.class);

public void logging(IStatus status, String plugin) {
if (status.getSeverity() == IStatus.WARNING) {
if (status.getException() == null) {
LOGGER.warn(status.getMessage() + "(" + status.getCode() + ")");
} else {
LOGGER.warn(status.getMessage() + "(" + status.getCode() + ")",
status.getException());
}
} else if (status.getSeverity() == IStatus.ERROR) {
if (status.getException() == null) {
LOGGER
.error(status.getMessage() + "(" + status.getCode()
+ ")");
} else {
LOGGER.error(
status.getMessage() + "(" + status.getCode() + ")",
status.getException());
}

} else if (status.getSeverity() == IStatus.INFO) {
if (status.getException() == null) {
LOGGER.info(status.getMessage() + "(" + status.getCode() + ")");
} else {
LOGGER.info(status.getMessage() + "(" + status.getCode() + ")",
status.getException());
}

}
}

}



and to register it


this.listener = new Log4JListener();
Platform.addLogListener(this.listener);
