Good books on CORBA?

[Henri Muurimaa <hezamu tuug fi>]

Having just started learning CORBA, I'm craving for some structured
explanation on the matter. Most of the papers I find from the web are
focused on some narrow aspect of CORBA, or are too shallow.

So what books on the subject would you recommend? A quick peek at Amazon
found me the Advanced CORBA Programming with C++ by Michi Henning and 
Steve Vinoski, but is it geared too much towards C++ to be of use with
ORBit?

Are there any other good books?
