Troy, Thanks for the analysis. We need to fix the pom for JPADemo archetype.
Can you please file a ticket for this (http://github.com/dpp/liftweb/issues)? We'll update the pom and resolve the slf4j dependencies. Cheers, Indrajit NB: We might just make it for M7 if all goes well. Else, it'll be available in the SNAPSHOT as usual.
