Re: [orca-list] orca, java access bridge and java

[Michael Whapples <mwhapples aim com>]

Hello,
Unfortunately I don't have any knowledge of corba, orbit or PyOrbit
internals, but I have got skills in both java and python. Depending on
how much there is to learn about corba and orbit I may be able to do
something to help. So would I be right in thinking, from what you said,
that loggers associated with corba and orbit would be one source of
information of interest for resolving this problem.

Regarding the key bug, I will see what has changed between orca 2.20.x
and orca 2.22.0 in the script you mentioned, as it was between the above
versions I noticed this particular bug occurring.
