Java Programming

I've long used the java.util.logging by having a logging.properties file and specifying the "java.util.logging.FileHandler.pattern" in that file and specifying the location of the logging.properties as a jmv arg (-Djava.util.logging.config.file=logging.properties). No issues with that.

I now, however, want to override the file pattern by using a jvm arg (-Djava.util.logging.FileHandler.pattern=somename.log), but when I do that, I get no file log output. If I leave it specified in the logging.properties it uses the value there and NOT the jvm arg value. If I comment it out of the logging.properties file is uses nothing (no file output).

I see (via Google) others using this parameter, but I am having no luck.

All in latest JDK release (6u11).

Can't find any documentation on doing this on Sun's site (it might be there, but I haven't been able to find it). Don't see posts of others having this problem. I've got the same results on linux and OSX, different releases and all.

Thanks for any insight in advance!
