omniORB is an Object Request Broker (ORB) which implements version 2.6 of the Common Object Request Broker Architecture (CORBA). It supports the C++ and Python language bindings, is fully multithreaded, uses IIOP as the native transport, and comes complete with a COS Naming Service. omniORB is one of the fastest available C++ ORBs.
TAO (The ACE ORB) is an advanced, CORBA-compliant, real-time Object Request Broker (ORB). It is designed to meet the stringent Quality of Service (QoS) requirements of real-time applications, resulting in superior end-to-end predictability, efficiency, and scalable performance. It implements the latest CORBA specifications from the OMG. It is built with components from the ADAPTIVE Communication Environment (ACE) C++ framework, resulting in a highly extensible architecture, adaptability to a wide variety of situations, and portability across a broad range of platforms. Although TAO was designed to meet the demanding requirements of real-time applications, it is also well-suited for general-purpose CORBA applications.
The SOAP to CORBA bridge/translator is written entirely in C++ and shows that it is indeed possible to do a generic translation of SOAP requests to CORBA method invocations and vice versa. This is implemented by using the CORBA Interface repository to match the incoming SOAP request to the corresponding CORBA service, build the dynamic invocation of the CORBA service, and generate the SOAP response (or possibly SOAP fault in the case of a CORBA user exception, for instance).
OpenCCM (Open CORBA Component Model) is an implementation of the CORBA Component Model (CCM) specification defined by the Object Management Group (OMG). The CCM is the first vendor neutral open standard for distributed component computing, supporting various programming languages, operating systems, networks, CORBA products, and vendors seamlessly. The CCM is the OMG's specification for creating distributed, server-side scalable, component-based, language-neutral, transactional, multi-user, secure applications. One CCM application can be deployed and run on several distributed nodes simultaneously.
QoS Enabled Distributed Objects implements a CCM and adds some more advanced features such as QoS extensions and interoperability with other middleware technologies. Please note that you also need the generator for implementing your own components, and it can be found at the same place.
SDE for NetBeans is a UML modeling environment tightly integrated with NetBeans. It lets you draw all types of UML diagrams (use case diagram, class diagram, sequence diagram, activity diagram, etc.) in NetBeans, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features a Rational Rose importer, an XMI importer, HTML/PDF documentation generators, and plug-in and template support.
