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);



Eclipse SWT 3.5 and an annoying change...

after I moved a part of my software over to eclipse 3.5 to take advantage of bug fixes and new features I noticed that some of my dialogs don't work anymore.

For example the login dialog has 2 fiels. A username and a password. These fields are defiend like this:


password = new Text(content, SWT.BORDER | SWT.PASSWORD);
user = new Text(content, SWT.BORDER);

user.addKeyListener(this);
password.addKeyListener(this);


and in the key listener I validate the inputs. But with version 3.5 key listener won't work on password fields anymore and I didn't find any documentation about it. So instead you need to use a modify listener now


password.addModifyListener(new ModifyListener() {

public void modifyText(ModifyEvent e) {
}
});
