I think the problem here is that the call to getInstance is in the
initializer of a static variable.  This means that it is getting run
when the class is first loaded.  I am not sure about when Tomcat fires
up its log4j configuration, but it is very likely that it is after your
static initialization gets run.  You could force the initialization to
happend before your call to getInstance by putting an explicit static
initializer in like so.

static Cateogry log;

static
{
  PropertyConfigurator.configure("log4j.properties");
  log = Category.getInstance(Invoice.class);
}

If you don't strictly need the Category instance to be static, you could
also delay the getInstance call  till the constructor.

    OK.  Well I commented that line out, still getting the No appenders error.
    
    My props file is /usr/local/resin/doc/WEB-INF/classes/log4j.properties.  I
    have my jar file in /usr/local/resin/doc/WEB-INF/lib/me.jar and resin
    picks it up fine, so I'm assuming that the WEB-INF/classes dir is also in
    the classpath.
