Middleware News Brief (MNB) features news and technical information about Open Source middleware technologies.
Using QuickFAST and OpenDDS for a Low Latency Market Data Feed
This article discusses the testing done to explore the combination of an open source decoder (QuickFAST) with an open source publish and subscribe distribution service (OpenDDS) using commodity hardware.
Multi-Language CORBA Development with C++, Java, Perl, and C#
This article illustrates multilanguage development with CORBA by implementing a simple client-server system written in each of four separate languages: C++, Java, Perl and C#, using four different open source middleware products: TAO, JacORB, opalORB, and IIOP.NET.
Using TAO and OpenDDS with .NET [Part III: DCPSInfoRepo Collocation]
This article examines the DCPS Information Repository and shows how it can be colocated into a server process with the help of various ACE classes.
Using TAO and OpenDDS with .NET [Part II]
This article demonstrates how to mix TAO and OpenDDS in a .NET application to implement a client-server system.
Using TAO and OpenDDS with .NET [Part I]
This article describes how to use TAO in a .NET application to implement both a CORBA client and server.
RMI Over IIOP with JacORB
This middleware-focused SETT article demonstrates how an RMI/IIOP server can be made available to the widest possible variety of clients without requiring client-side code changes.
An Introduction to TAO's Asynchronous Message Handling
This article compares synchronous request processing with AMH, explains how IDL-defined interfaces are modified for use via AMH, and presents a sample application.
An Introduction to OVATION
This article provides an overview of Object Viewing Analysis Tool for Integrated Object Networks (OVATION), an open-source toolset developed to assist in the debugging, diagnosis, and analysis of distributed applications.
Request-Processing Aspects of CORBA and TAO
Controlling how CORBA requests are processed is one way in which an ORB can be aligned to meet an application's needs. This article explores request-processing aspects of CORBA and TAO.
Introduction to Fault Tolerant CORBA
In this article, we demonstrate how the Fault Tolerant CORBA specification provides developers with mechanisms they can use as a framework for building resilient, highly-available, distributed software systems.
