Eclipse logging and Log4J [message #302305]

Is it possible to redirect the eclipse logging (which is default written
to a .log file) to (for example) Log4J?

I am looking for a solution to get the logging of my eclipse plugin
(including logging generated by eclipse core) and the logging generated by
a jar file (which I use in my plugin) into one logging file.

Create the class below and but in your Plugin startup code this:

<code>
Platform.addLogListener(new EclipseToLog4J());
</code>

Its only a quick hack. The comments are in German, sorry.

This is the logging class:
<code>
public class EclipseToLog4J implements ILogListener {

private static final String PREFIX = "eclipse.";

/** Hier werden die Loggers gecacht. Key ist der pluginnamen ohne den Prefix */
private Map loggers = new HashMap();

/**
* Gibt das Logging Event von Eclipse auf log4j aus.
* Als Loggernamen wird "eclipse." plus den Pluginnamen genommmen.
*
* @param status das Logging Event
* @param plugin Name des Plugins, welches die Ausgabe verursacht hat
*/
public void logging(IStatus status, String plugin) {
Logger log = (Logger) loggers.get(plugin);
if (log == null) {
// Noch nicht angelegt
log = Logger.getLogger(PREFIX + plugin);
loggers.put(plugin, log);
}

Priority prio = Priority.INFO; // OK, cancle usw --> Info
if ((status.getSeverity() & IStatus.ERROR) != 0) {
prio = Priority.ERROR;
} else if ((status.getSeverity() & IStatus.WARNING) != 0) {
prio = Priority.WARN;
}
if (log.isEnabledFor(prio)) {
log.log(prio, status.getMessage(), status.getException());
}
}
</code>

You might have a look at the article "Universal Logger Plug-ins for RCP
Applications" from John Franey. You can find it through www.eclipsezone.com.
