IIOP.NET is an opensource product to provide seamless interoperation
between .NET, and CORBA or J2EE distributed objects.
It is a remoting channel implementing the IIOP protocol for the .NET
environment, the same protocol
used by Java's RMI/IIOP and all CORBA ORBs. Objects defined in a .NET
application are made
accessible to other remote ORBs, and vice-versa; EJBs become also accessible
to .NET without any modification
of the original beans.
Two tools are also included in IIOP.NET: an IDL generator to create the
IDL description of the remotely
accessible .NET objects, and an IDL compiler to translate IDL definitions
into .NET metadata and code.
The source code is released under the LGPL on sourceforge (
JacORB is an object request broker written in Java, available under the
LGPL. For a complete list of details, and to download, go to
JacORB is also available for free download at the github site https://github.com/JacORB/JacORB
is an source CORBA implementation for the Ruby Programming Language
created by Remedy IT.
VBOrb is an Object Request Broker, written entirely in Visual Basic 5. With VBOrb you can write CORBA Visual Basic clients and servers. CORBA clients can call methods of remote objects written in any language and CORBA servers can call back methods of your local objects. For instance you can write your server in Java
using a JavaORB and your client in VisualBasic using VBOrb. CORBA is an open standard in opposite of Microsoft DCOM or COM+. CORBA is specified by the OMG. VBOrb comes with an IDL to VB compiler
called IDL2VB. The compiler is written in Java.
You can download VBOrb at:

for OMG IDL
Below are two downloadable files for OMG IDL provided under open
source license by Arno Puder. For the scanner and the parser (in
lex and yacc format). The grammar conforms to the official 2.3
revision of the CORBA specs.
The acronym MICO expands to MICO
Is CORBA. The intention of this project is to provide a freely
available and fully compliant implementation of the CORBA standard. MICO has become quite popular as an OpenSource project and
is widely used for different purposes. As a major milestone, MICO has
been branded as
by the OpenGroup, thus demonstrating that Open Source can indeed
produce industrial strength software. Our goal is to keep MICO compliant to the latest CORBA standard. The sources of MICO are placed
under the GNU-copyright notice.
The current version of MICO includes
the following features amongst others:
- IDL to C++ mapping
- DII, DSI, Any, DynAny, Iface Repo, Impl Repo
- Value Type Semantics
- IIOP as native protocol (ORB prepared for multiprotocol
- IIOP over SSL
- Full BOA and POA implementation
- Naming service
- Trading service
- Event service
- Relationship service Property service
- Time service
The ACE ORB (TAO) is an "open source", high
performance, CORBA 2.2 request broker. Originally designed for
the world of real time it can provide you with defined Quality
of Service as opposed to "Best Effort". TAO supports
many O/Ss: most flavors of UNIX, Linux and NT, as well as real
time systems such as Lynx, PSOS and VxWorks, and embedded
systems like Windows CE. TAO is based on the widely used
Adaptive Communication Environment (ACE) library or pattern
framework. As result TAO has a very flexible architecture and
thus can easily extend across platforms. Moreover as systems and
networks add features to support a variety of Quality of Service
parameters, it can rapidly incorporate those new techniques and
strategies in order to optimize for those environments. Its
small footprint, scaleable design and highly predictable
performance makes it the only ORB with complete end to end
determinism and the first choice for the discriminating
TAO may be freely copied and commercial support for ACE/TAO is available
from Object Computing Inc. at
and Remedy IT at www.theaceorb.nl.
of Mannheim Interoperability Scenario
Manneheim University has built an interoperability scenario
using different ORBs (including naming and event services). The
sourcecode for the servers and clients can be downloaded. Visit
the webpage at
Manneheim University homepage at
This page now has an English version as well.
CORBA Interface Testing Toolkit
MCITT ("M-kit") minimizes the amount of effort needed
to produce simple emulations -- test servers -- that can be used
to replace actual servers in a testing scenario. The person
doing the testing only needs to specify the behaviors that are
important for the specific scenario being examined, and MCITT
will do the rest. CORBA boilerplate code, memory management, and
stubs for unused operations are generated automatically. MCITT
also provides conformance test assertions, automatic inclusion
of conformance test boilerplate, and timed loops for performance
evaluation. Test assertions can even be derived automatically
from Component Interaction Specifications.
CorbaScript Language ( not available at this moment http://corbaweb.lifl.fr/CorbaScript/)
CorbaScript is an interpreted object-oriented scripting language
dedicated to CORBA environments. Scripts (i.e. CorbaScript
programs) can invoke any operation, get and set any attribute of
any Corba object. Moreover, any OMG-IDL interface can be
implemented by scripts. CorbaScript provides a dynamic binding
to OMG-IDL descriptions: no OMG-IDL stub or skeleton need to be
generated. OMG-IDL descriptions are extracted from the Interface
Repository and are made directly available to scripts.
Invocations of CORBA objects are achieved by the CORBA DII
mechanism. The CORBA DSI is used to implement CORBA objects with
CorbaScript. Moreover scripts can invoke any world-wide CORBA
object through IIOP.
CorbaScript fully hides these complex
CORBA mechanisms via a simple, attractive and powerful scripting
omniORB is a robust, high performance CORBA 2.3 compliant ORB with
C++ and Python bindings. Features include:
- IIOP™ protocol is used as the native protocol

Telefonica I+D has an ORB released under GPL in Morfeo
OpenSource free-software community , and it's free available
for download. It is aligned with CORBA 2.6 (including POA, DSI,
DII, DynAny, AMI, QoS timing policies, GIOP compression,
Bidirectional GIOP, IPv6, etc.) and it includes Notification and
Naming CORBA services.

ILU CORBA implementation
The Inter-Language Unification system (ILU) is a multi-language
object interface system. The object interfaces provided by ILU
hide implementation distinctions between different languages,
between different address spaces, and between operating system
types. ILU can be used to build multi-lingual object-oriented
libraries ("class libraries") with well-specified
language-independent interfaces. It can also be used to
implement distributed systems. It can also be used to define and
document interfaces between the modules of non-distributed
programs. ILU interfaces can be specified in either the OMG's
CORBA Interface Definition Language (OMG IDL), or ILU's
Interface Specification Language (ISL).
