Hi all,

I started looking at what Stephen did with the crypto service, and it is
very interesting.  The Turbine dev team knows we need to come up with
something better then ECM, however we just haven't gotton around to writing
either a good FortressComponentService or MerlinComponentService.  However,
if someone has something that they could contribute, that would go a long
way towards getting the ball moving on getting the various services in the
Fulcrum project moved towards Merlin.
There are some recent additions to Merlin related to the 
AbstractMerlinTestCase (which itself was written to handle Turbine test 
requirements).  These additions include a new class called MerlinLoader 
that simplifies the overhead of embedded containment.  There are also a 
bunch of discussions going on over in Avalon land about the embedding 
subject with input from the Eve project (ldapd incubator inative), 
OpenIM, and others - taking into account requirements from the OpenORB 
project, JBoss, etc.

I've been going over the Fulcrum code base and based on everything I've 
seen so far it looks like everything could be supported in Merlin under 
the current formal release (3.0). The testcase and plugins related to 
Avalon meta-info generation are all in place and working nicely relative 
to 3.2 dev (which is runtime compatible with 3.0).  I expect to see some 
interesting development on the embedded services and the abstract test 
case code over the comming days.

Before Turbine 2.4 release, which is focusing on integrating all the
services moved to Fulcrum, we need to basically pick our container to run
with..  We don't want to go with Fortresss/ECM, and then in 2.5 start
swapping to Merlin which could require config changes, so it is definitly on
the list to get the MerlinComponentService written.
What is the projected release date for 2.4?

My guess is that it would not take much time to bring Fulcrum up-to-date 
with respect to the Avalon Meta package and provide fine-grain component 
test integration (along the lines of the crypto package example).  I can 
continue to transform a few more of the Fulcrum packages along the lines 
of the crypto transformation if that is of interest.

Stephen.

you mean tomcat/jerry running as a merlin service OR merlin

Both of course! :)

Actually, there's a couple things that would be cool here:
- Tomcat/Jetty running as merlin service
- An Avalon light weight servlet container (which adds avalon
lifecycle support to servlets)
- Easy way to access Avalon services from within service,
     

action, etc.
   

(this can be done via AltRMI or JNDI, but we need to put
     

together docs
   

and examples)

I'm not very familiar with Turbine, but it would be nice to
     

see Turbine
   

services running in Fortress and Merlin without too much trouble.

     

Hi Aaron:

Confession - I'm not familiar with Turbine either.

I have played around with Turbine Fulcrum a bit - did some
treaking of the
crypto package and things are working fine (using crypto
component).  I've
got a local copy running against Merlin 3.2 using the new test case as
part of own my own test-and-validation-release-suite.
I'm interested in the Avalon/Turbine connection because I
would like to
play with the potential of Turbine as a smart web-service
system that we
plugin on the container facilites side of merlin.  I'm also a
interested
in potential applications of Turbine on the server side (just
a hunch).
Cheers, Steve.
