Has anyone given any consideration to this question? I've since tried configuring using PropertyConfigurator on a properties file in the jar but it too raises a NullPointerException in the configure method. Runs fine in appletviewer, but not in a web browser (IE or NS). I even tried creating a simple, hardcoded configuration by creating a new Properties object and using setProperty calls. It too resulted in a NullPointerException.
I've burned quite a bit of time trying to find the cause of this. My next step is to invoke the commandline debugger in the Java Console and step through the code. Please, does anyone have ideas of what is wrong here.
