I started working on something like that at work, and we will eventually open source it.

For now, I can use Slf4J in my client code. In DevMode, it will use whatever Slf4j implementation it finds in the classpath (which means that it will write to the console, not to the DevMode window), and it compiles out in prod mode.

I've been thinking recently about just wrapping java.util.logging (and using jul-to-slf4j.jar to format my logs using logback) instead of my default, emulated NOPLoggerFactory (used in web mode only), but we actually don't use it that much in client code (and overall), so I didn't invest any more time in it for now.

There's also a project on GitHub: https://github.com/derjan1982/slf4gwt more like gwt-log than JUL integration in GWT though, IIRC.

 

I would like to be able to use logging.properties file to define formatting,
which I believe is not possible with java.util.logging.

I believe you can (at least in DevMode I mean, or when using a RemoteLogHandler), though you might have to make your own Formatter class (or pick a third-party one).
