Subject Re: Integrating JAX-RS runtime into DOSGi
Date Thu, 11 Jun 2009 14:41:22 GMT
Great, I'm glad this is helpful.  And thanks for explaining the redundancy
regarding databindings... that makes sense.

I'd seen your comments about "model info" earlier in this or a related
thread, but I don't know what "model info" is.  Perhaps this is a good time
to hand over the reigns to you?

Thanks,
Josh
