Mike Duller from ETH Zurich has successfully run Concierge on a Sony Ericson M600i. He used this launcher and the following init.xargs file to get it running on the j9.
# uncomment the following line if you want to relocate concierge's basedir # from its private application directory to the memory stick #-Dch.ethz.iks.concierge.basedir=d:\other\concierge -Dch.ethz.iks.concierge.jars=file:d:\other\concierge\bundles -Dch.ethz.iks.concierge.log.enabled=true -Dch.ethz.iks.concierge.log.level=4 -init -istart splash_screen-0.6.2.jar
Thanks, Mike.
