Just tried it on master, I see the ResourceAdapter being activated.
Looking at your log it look like the @Connector bug we have fixed some time ago. You could try using IronJacamar 1.0.14-SNAPSHOT with master which will explode if the resourceadapter-class isn't defined. Or you could add a ra.xml file with just that element (as a work-around).
filesystem.rar sounds like http://xadisk.java.net/ - but I didn't look at your source ;)
