How do you bind a EJB home to a COSNaming service ?

Question

Hi All,
I am trying to have a corba client(written in java) communicate to an EJB,
but I am facing a few problems. As per the procedure specified by the BEA documentation
I have created the idl files. Then using the idl (idl -jpoa=. -jbase=. Hello.idl)
command I have created the respective java classes. But I am not sure wether
the Weblogic server by default binds the EJB to a COSNaming service or not(In
Borland App server it binds to a COSNaming service). Incase it does not then what
do I need to do, to have the EJB bound to a COSNaming service. Generally how do
I find out wether a Home Interface is bound to a Naming service? I am using Weblogic6.1
app server and IONA Orbix 2000.
Regards,
Ameet.

Hello Andy,
Thank you very much for your reply. Forgive me sending out several
messages, just to try to reach you. You can tell how frustrated I am
with the issue. The O2K version I tried is 2.0 came with E2A application
server.
Have you tried Orbix 3? and any luck of it? What do you think is
the effective way to push IONA to fix the bug?
Thanks,
Qing

Yeah, this is a bug in the Orbix 2000 idl compiler, I ran into this
when I tried it and couldn't find any workaround. I reported the
problem to Iona but I don't know whether they did anything about
it. Incidentally what version of O2K is this? I tried with 1.2 and was
going to try 2.0 - but if this is with 2.0 I won't bother.

As far as I know, BEA implemented COSNaming wrapper around their JNDI.So EJB
got bound just like in the normal case and your client uses COSNamingto get
reference.
Do you have any experience with CORBA C++ client (Orbix 2000) callingEJB? I have
problem with it. I can generate stub files with Orbix idl compiler.
But when I link stubs with the client.cpp, I got the following:
[exec] clientC.cpp
[exec] client.hh(1008) : error C2327: 'IT_Gen_DynamicProxy_EJBHome::EJBHome
::EJBMetaData' : member from enclosing class is not a type name, static,or enum

Any help will be appreciated.
