[rules-dev] Accessing JCR repository directly

[Michael Neale]

Hi Bernd. yes you have it correctly - seam starts things up.

IN terms of accessing JCR directly, this came up before and one idea was to
use the "remote" JCR interface - that means some refactoring I guess.

So the basic design is that there is a JCR server that starts up, and the
"clients" connect remotely (a client in this case is also the Guvnor server
side).

That way you can access it from multiple places. However, it may be a bit
too low level for this - the question is what do you want to access JCR for
from your external app?

A better approach, is to make the ServiceImplementation a true remote
interface (at the moment it is, but for GWT clients only) - so ANY sort of
client can connect and access the guvnor services, without messing with low
level data structures - I am thinking the latter is the superior approach
(and someone else was looking at it).

Michael.
