A simple way to check which Orber-version you are using is:

If you don't run Orber as lightweight the exception above is thrown when
Orber attempts to decode a message (e.g. Reply, Request).

I'm afraid their assigned values are not documented.

Probably not. However, the Orbix IIOP implementation was buggy prior to
Orbix-3.3 (patch 20); sends garbage on the wire in some cases. Consult:
Most of the changes in R7B-3 was to reduce overhead and adding new
features. The bug-fixes shouldn't have any impact on your application.

Even though it's not documented (prior to 3.2.5) you can set the
configuration parameter 'orber_debug_level' which will generate printouts
when something abnormal occurs (NOTE, not always errors). Usage:
shell> erl -orber orber_debug_level 10
Please supply all printouts and the exact Orber-version.
The most common mistake is that the IDL-specs isn't registered in the IFR.
When compiling your IDL-file(s) erl-module(s) (named 'oe_XXX.erl') is
generated and contains the function oe_register().
If this doen's solve your problem please e-mail again.
