[logback-user] Time and Size-based rolling policy not working

I have created a test project to see if I can use logback's size and time-based rolling policy to roll over to log files as logs get large and as time passes. However, I cannot get it to roll over. It instead always logs to the file I've specified in the <file> tag. I have attached my project's full, ant-buildable source code to show my code and to possibly help get the ball rolling on figuring all of this out. Can anyone help me get time/size based file rolling working? http://old.nabble.com/file/p28171419/logback.zip (This is the Java project)
