Yes as always we want our users to plug in whatever service they want to use if they don't want to use their own, so the JAXR api seems the way to go for interacting with the registries (inluding our own). So hopefully we can keep the esb code free of UDDI. However, for the implementation the registry itself, I'm not yet sure how that is going to play out, but you'd think that if we will use JAXR to call it we will have no need for UDDI specifics, since we can't call it anyway. So, in short, the answer is yes that is still the current idea :). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965798#...
