The ACE ORB

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.

            Good Product... Not Open Source
            I know, the license says gpl, but...

            The CORBA standard is a huge and useful universe of tools and functionality. All of which the ACE ORB (TAO) encompasses. And while there is online documentation and a list serve of users, the documentation is little more than a teaser and the support from the list serve is at best limited. In fact, many queries are directed to a commercial support site.

            When you realize that the developers are also pushing you to buy their $250 USD manual in order to figure out how to operate their little gem in the real world, it becomes obvious this is nothing more than a thinly descised commercial product.

            I thought long and hard about writing this review, but after using this product for more than a month, I have to say that I just can't recommend this product for inclusion in any products, GPL or commercial. The licensing for it is dishonest.

            There are plenty of other CORBA platforms out there: Orbit, Mico, etc., use one instead. I've been a C++ advocate for years, and have been surprised that more free C++ implementations of CORBA haven't materialized. Unfortunately, while this one appears to have the proper credentials, don't be fooled. It's commercial documentation prerequisites make it effectively a $400 USD solution in documentation + additional costs in commercial support.
