J-Integra Espresso is a high performance middleware bridge that enables Java .NET Corba interoperability. It offers software developers a simple and flexible way of allowing applications built with Microsofts .NET framework to interoperate with Java-based and CORBA-based systems without having to change existing systems or acquire additional hardware/software infrastructure.

J-Integra Espresso is a true CORBA solution for the Microsoft .NET framework. This ORB (Object Request Broker) has been written entirely as managed C code and can therefore be accessed by all .NET languages (C, ASP.NET, etc).
