Hi,
I am using JacORB only on the client, the server was Yoko. If I
generate the stubs with JacORBs tool it works ok - I can comunicate
with service implemented in Yoko sucessfuly.
I have other problem: there is no problem to work with JacORB client
and Yoko service. The corbaloc protocol works great but I want to try
the other direction: JacORB service and Yoko/CXF client. The problem
is simple: I am not able to create JacORB service exposed via corbaloc
protocol. I do not how to do it.
I am trying to use IOR file now (and pass it to Yoko client with
"file:./my_ior.txt"), I hope it will be possible. But in near future I
will need to use corbaloc protocol...

Hi Lukas,
Just a quick update. I'm still working on trying to reproduce the BAD_PARAM
exception using JacORB. So far I have yet to see it and I've also
successfully managed to get a JacORB client to talk to a Yoko server.
I'll continue to try and reproduce the exception tomorrow.
Cheers,
Darren

now I'm going to move onto trying to set things up with JacORB. Just a
quick question...are you using JacORB for just the client or are have you
changed the configuration for the Yoko binding on the server side to use the
JacORB ORB classes as well?
