This is a pure Java, run-anywhere, Fix Engine with a very simple to use event-based API. You can run this fix engine on any system that has a JVM (JDK or JRE 1.2 or higher is required). NB: the event-based API is implemented on-top of a 'low-level' API that is compatible with the API in Octatec's FixGateway product.

This is a Fix Engine and API written in C++. There are versions available for WINDOWS and Linux(x86). (The API is compatible with the ‘low-level’ API provided with AFI/J). The WINDOWS version of this package also includes an Active X Control interface

Also (separately) available for the WINDOWS platform is a C#  interface package. This interface packages provides an alternative to the C++ library or Active X control interface

Also (separately) available for the WINDOWS platform is an SSL integration kit, which allows you to make Fix connections over 3rd-party SLL products.
