You forgot to mention that a JCache implementation can be
distributed, so you get state fail-over. This is on important part
of supporting clustering. The RI doesn't support this, but I believe
that ActiveSpace does.

Jacek,
I am working on OpenEJB 1, since OpenEJB 2 is Geronimo centric.
JSR-107 is a Java caching system that will help OpenEJB have quicker
reponses when issueing up EJBs. When a user needs an EJB instance,
now you
always get a new EJB. With a cachine system, some EJBs will be
cacheable
and when called will be delivered from cache instead of creating a
new EJB,
which could have external calls as well like JDBC queries and
such. The
overall benefits would be better performance for the EJBs. We got
the spec,
and reference implementation, from James Strachan. I have just
finished the
spec and as I get reacquainted with OpenEJB source I'm sure things
will
change with my initial ideas so, as I told Dain, I plan on getting an
initial version working and then we can discuss improvements on
support and
efficiency. As far as a timeline, I'm not 100% sure at this point. I
haven't looked at OpenEJB source in almost 14 months so the
majority of my
time will be spent getting back into the source to better learn the
OpenEJB
architecture. As soon as I have a better understanding I will
post. I hope
this answers your questions but feel free to ask for me depth.
Take care,
Jeremy

OpenEJB-Dev,
Work has began on the integration of the JSR-107 reference
implementation into OpenEJB. If anyone is interested in being
involved or
has questions, respond back to this email so we can keep track of
all of
the
development. Take care,
Hi Jeremy,
I don't know JCache and JSR107, so I'd be glad to hear what
benefits it
might bring and when you envision it's going to be available? Are you
working on OpenEJB 1 or 2 codebase?
