Exception when using CORBA in 2.0 M5: "Invalid ORB class"

[Michael Ivanov]

I am very new to using Geronimo, and recently switched from 1.1 to 2.0
M5.  I deployed my application fine, and most aspects seem to work
great except CORBA.  When my application initializes the ORB, by
calling

org.omg.CORBA.ORB global_orb = org.omg.CORBA.ORB.init(no_args, null);

it fails with the following stack trace:

org.omg.CORBA.INITIALIZE: Invalid ORB class:
org.apache.yoko.orb.CORBA.ORB:  vmcid: 0x0 minor code: 0x0  completed:
No

Again, everything worked fine in geronimo 1.1 and previous versions.
Thanks for any hints.
