FW: What version of CORBA ORBit to use? Trying to get perl client to talk to BEA Tuxedo 8.0 server...

Hi All,

I have three groups of question.  Going from most general to most =
specific:

1)  I'm hoping to find a way to write a client application in perl that =
makes calls against the IDL interfaces of CORBA servers hosted by BEA =
Tuxedo 8.0.  Has anyone already done something like this?  Am I on drugs =
for even wanting to try?  Tux 8.0 supports CORBA 2.1 and 2.2 and IIOP =
1.2.  Tux 8.0 claims to support Interoperable Naming Service, so I was =
hoping to get an initial IOR to the Tux NameService that way.  I see in =
http://icps.u-strasbg.fr/~genaud/ORBIT/c42.html#AEN66 that ORBit does =
_not_ yet support INS, although I swear I saw in other docs that it does =
(i.e., http://orbit-resource.sourceforge.net/faq.html).

2) What is the most current version of the Perl mapping for ORBit?  What =
version of ORBit should I use with it?  Is there/where is a Perl mapping =
for ORBit2?  I saw mention in the mailling list archive that a perl =
mapping branch was going to be added to ORBit2, but I don't see anything =
perl related at http://cvs.gnome.org/lxr/source/ORBit2/. I'm currently =
using CORBA-ORBit-0.4.5 from CPAN and ORBit-0.5.17, and I'm seeing the =
bug below so I haven't even tried to talk to the Tuxedo ORB yet.

3) I get a crash when I try the example code in the CORBA-ORBit-0.4.5 =
examples.  Any idea what is going wrong, or what I'm doing wrong?  It =
looks like I'm sooooo close it's infuriating...

[so it looks to me like the POA was mostly properly initialized, but =
init_local_objref was left set to 0 for reasons I don't understand]

I get the crash if I wait for the server to finish counting down before =
running the client or I run the client while the server is still =
counting down.  I'll admit I'm not exactly sure what the server is doing =
while couting down.

The example above uses perl 5.005_03 built for sun4-solaris on a Sun =
E450 runing solaris 2.8 and ORBit-0.5.17.  gcc information is below.  =
I'm using glib 1.2.10.  I see the same crash behavior whether I use perl =
5.005_03 or perl v5.6.1 built for sun4-solaris

4) I guess I now also have a 4th question:  what's the right/most active =
group to send questions like this to?  Is orbit-perl-list@gnome the =
right place?  I had tried the COPE mailling list at =
http://www1.lunatech.com/cope/, but that seems to be lower activity.

Many, many thanks,
