Efxclipse/Runtime/Recipes

This page holds best practice recipes when writing JavaFX application using e(fx)clipse

Core

Logging

e(fx)clipse has its own logging facade org.eclipse.fx.core.log.Logger which allows to plug-in different log frameworks.

Currently available are:

• java.util.Logging (default)
• log4j by adding org.eclipse.fx.core.log4j bundle to your OSGi-Runtime

Usage

There are different ways to use get a logger.

LoggerCreator

If you are running on OSGi you can add the org.eclipse.fx.osgi.util bundle which provides access to the LoggerCreator factory class

import org.eclipse.fx.core.log.Logger;
import org.eclipse.fx.osgi.util.LoggerCreator;
 
public class MyClass {
  private static Logger LOGGER = LoggerCreator.createLogger(MyClass.class);
 
  // ....
}

LoggerFactory Service

The different logger bundles contribute their LoggerFactory implementation into the OSGi-Registry. In case you are e.g. contributing a service via DS you can get simple add a service reference and you'll get the LoggerFactory with the highest rank injected.

import org.eclipse.fx.core.log.LoggerFactory;
import org.eclipse.fx.core.log.Logger;
 
public class MyServiceImpl implements MyService {
  private Logger logger;
 
  public void setLoggerFactory(LoggerFactory factory) {
    this.logger = factory.createLogger(MyService.class.getName());
  }
 
  public void unsetLoggerFactory(LoggerFactory factory) {
 
  }
}
