Not a bad talk. this is what I took away from it:

• SOA is technology agnostic
• SOA is about loose coupling, not about distributed RPC
• SOA infrastructure should support/encourage SOA principles
• The ESB glues other technology together, allowing an incremental approach to SOA. Don't try to do a big bang!

It was a first view of JBossESB for me.

Apparently it's a combination of several tools (not uncommon with ESB's): Brools, JBoosWS, JBossTS, JBossMessaging en JBPM

It's nice that it can run in the JBoss appserver, but also in other appservers.

All in all, my impression (not based on detailed research) was that the product is not very mature yet. Illustrating this:

• failover/clustering technology is still under construction
• whole modules are scheduled to be rewritten/drastically improved next year.

Compared to another ESB that I know a bit better (Sonic ESB), this product seems to be not of the same standard (yet)
