Hi,
I think it's good idea to share some code between CORBA and EJB bindings.
Here is my view:
1) binding.corba provides the transport support for IIOP
2) Most pouplar JEE/EJB containers support RMI/IIOP for EJBs. RMI/IIOP is
built on top of RMI and IIOP.
3) For the reference side, we can use the RMI/IIOP protocol to access EJBs
as CORBA services (that's how we implement the EJB reference binding in
Tuscany today).
4) For service side, we can potentially expose SCA components as CORBA
services over RMI/IIOP following the EJB patterns. This way, we can have a
poor-man's EJB container to support POJO as EJBs.
Thanks,
Raymond

Subject: Re: The integration test for binding.corba is working now!
Hi Tuscany Developers,
I'd like to thank you (especially my mentor Raymond) for support and help
which was given to me - I wouldn't made this far without you all!
First development phase of GSoC is almost over so here's quick summary.
Goal was to implement binding extension for CORBA. Most of features were
implemented (there are still few features unresolved, which I hope to
solve next week) - info and status of project can be found under [0].
Initially planned module binding-corba turned into modules binding-corba,
binding-corba-runtime, host-corba, host-corba-jdk. There is also
implementation of itest-corba, which was planned on 2nd development phase.
:)
After finishing CORBA binding next step will be implementation of
interface-corba-idl module, which is second goal of "CORBA support for
Apache Tuscany" Summer of Code project. I've enjoyed working on Tuscany so
far and I'm looking forward to have more fun and challenge witch Tuscany.
BTW,

I'd like to extract some common code to new module (corba-common or
corba-util) that binding-ejb-runtime and binding-corba-runtime could use
it. Is it acceptable?
Thanks again,
Wojtek

Hi,
I have applied the patches and now the integration test for binding.corba
is working and added to the main build! Thanks Wojek for his great
efforts to drive the GSoc project forward to this milestone.
Congratulations for his great success in the midterm :-)!
There are a few things I suggest you do as the next steps:
1) Merge the code from [1] to add the support of name mapping between
java methods and CORBA operations.
2) Refine the model for binding.corba.
We now have three parameters: host, port and name. We should support the
"corbaname:" URI too. For example,
"corbaname:iiop:[EMAIL PROTECTED]:2089/NameService#a/b/MyService".
3) Do we support the name in the format of JNDI name such as
"a/b/MyService"?
Thanks,
