Any CORBA security book to recommend ?

[Ketan Gathani]

hi,
I am currently working on CORBA security. I bought the java security handbook by Jamie Jaworski. This book is informative but however it lacks examples. I came across another book "Enterprise Security with EJB and CORBA" written by Bren Hartmen. Has anyone read this book ? Any other recommendations ? Basically I want a book which provides numerous examples to help me in implementation.
Any help is much appreciated. Thanks.
