public class Logger

extends java.lang.Object

Logger.java

All of the SWT uses this logger to record debug and error messages. Many people prefer different loggers, though, so this code redirects its messages through a "LogShim" class, that can route messages off to a different logging framework.

For example, you can use the LV2 logger from SWZoo (see http://www.swzoo.org), which very nicely allows the use of a Jini logging service to collect log messages from other services.

You could also write a log shim to use the JDK1.4 logging framework, or Log4J, or any other logger.

By default, this code uses a simple "internal" logger that dumps messages to stdout and stderr. You can change the behavior of the logger to use a different LogShim by setting the value of the swt.logger property to a fully-qualified classname of a class that implements the LogShim interface (defined in this package). If the class can't be loaded, then the simple internal logger is used by default.
