I pulled down the code an it looks like a lot of IIOP stuff is
there, what is missing for a full ORB? I'm not sure how I can help
with this without the full orb code. If we had that, I could try
integrating it into OpenEJB, but I am completely lost.
Sure, there is not an orb there yet; and so I understand your point
of view. What's not there is a lot of stuff, including all the
server-side handling (POA implementation), as well as local
invocation semantics (i.e., avoiding serializing arguments for local
calls). And also the character encoding stuff is not in there, since
the original trifork orb only implemented the absolute minimum
requirements to support isolatin-1 and 16-bit unicode. This is
probably fine for most western countries, but will not do it in
arabic or eastern asia. So there's a lot of stuff missing.
Let me repeat what motivates me: I'm sick and tired of being the only
one at Trifork that really knows the CORBA implementation, and this
is my chance to get out of it. I'm willing to put a lot of effort
into making a new free orb (that Trifork can also use), but I want to
make sure that I'm not the only go-to guy for problems with it when
we're up and running. So, Trifork needs an orb as much as Geronimo
does, but at the same time we want to get out of the CORBA business.
Also, I want to take this opportunity to avoid doing some of the same
mistakes I did in the first implementation, and get many things right
(as you like to say you do with Geronimo). So this is also a chance
to do some things much better. For these reasons I want to be part
of writing a new ORB.
The integration between CORBA and OpenEJB as it is right now in G is
quite standard; using standard POA interfaces and so forth, and so
here I don't expect that there should be any serious issues once we
get to that point.
Integrating security and SSL is something where every orb is
different because as far as I know this is not spec'd (or is it in
CORBA 2.6?). But here, we can do whatever fits best with what is
already there in the Geronimo code.
I had this same problem with the last IIOP donation, which was also
just IO code, and I hope to not repeat the experience.
There is no doubt in my mind that we should build a complete stand-
alone and quality ORB. Once we're up and running, we might even see
Sun chime in, and have them adopt this the same way we've seen with
many other Apache Java projects. There - that would be a goal.
What is your plan to get people involved?
I think we need to spend some time talking here about goals and
priorities, and then I would expect that the people that are
interested and capable of helping out would come forward as part of
such discussions.
One interesting discussion that you brought up at EURO-OSCON is the
relationship with ActiveIO. So. I'll post a separate mail on that
issue.

----------------------------------------------------------------
As has been discussed previously, Trifork wants to donate a CORBA
implementation. This message is to get things really started in
context of Geronimo. Along with this message is a tar ball of the
initial contribution, and I want to take this opportunity to
describe what we are donating and how we would like to do this.
To set things straight, will not be donating a full CORBA
implementation up front. What we are proposing is to donate the
resources (read: developers) that it takes to do a full CORBA
implementation in context of Apache Geronimo. Our concern with
donating the full code is that we want to ensure that this is
built as a community effort, so when we're done we are not the
"single point of failure" for this to succeed as we go forward. We
would like to avoid being the only ones to know the code, so that
the CORBA implementation that comes out of this is something that
can have a life without us pushing it forward. This is really the
principal value that we see in contributing to this project. We
want to have a free and independent CORBA implementation too, but
we would like to avoid being stuck on it as we go forward.
Having said all that, we do have a CORBA implementation; and in
our effort to bring this forward we will definitively use bits,
pieces or even large chunks of this to make the Apache Geronimo
CORBA implementation be complete and successful.
We know that there is eagerness in the Geronimo community to get
things started in building a CORBA solution, and so hopefully this
first contribution will be accepted as a starting point from which
we will build a world-class CORBA system.
What is in this package is the foundation of a new I/O subsystem
that I have previously talked about, and some of the code to hook
that up with the client-side of the CORBA stack. As such, thins
chunk of code is not in even self-contained nor complete. It's
just the state of the code in our lab right now, and we want to
move this into Geronimo space before we get too far along.
The mile stones that I imagine moving forward from here would be
something like this:
1. Client-side stream-based invocation.
2. Value semantics (object serialization)
3. Server-side stream-based invocation handling, including POA
implementation.
4. Dynamic stubs.
5. Local invocations.
There are a ton of sub-projects that I would love to see someone
starting on; some of which already have place holders or stubs in
the code that is part of the tar ball attached to this.

Kresten,
Can you take the main comment of the JIRA and post here on the
list? Having a threaded discussion in JIRA is awful.
Welcome, thanks for the contribution, and I look forward for more
discussion here.
