Tamale Sponsors Development Challenge for CsIL

CsIL

The CsIL project provides libraries to connect .Net applications to JBossMQ, the JMS implementation in JBoss 4.

Please download and try CsIL's XIL2.
A comprehensive design and deployment document is available for the XIL2. You may also communicate with the CsIL team via the csil sourceForge project pages.

Overview

CsIL is comprised by:

XIL2, A JBossMQ Invocation Layer implementation, written in Java and deployable in JBoss4. XIL2 is based on the JBossMQ standard UIL2.
CsXIL2, C# library that provides JMS-like facilities for messaging.

The Java and C# components communicate via a platform independent wireline protocol. All of the communication is conducted in a three layered protocol:

Command Messages. The top level protocol is a set of commands transmitted as "messages". This is the core of the XIL2 communication strategy. Commands are broken into requests and responses, which have identifiers. This allows one socket to be used for many different invocations from client to server and from server to client.
XML Encoding. Each message has an xml schema associated, so the request and the response can be transmitted in a platform/language neutral fashion.
Fixed Size Byte Blocks. Messages are broken up into fixed size byte blocks for transmission. This allows marshaling and demarshaling of the xml to be written directly to the network stream, rather than to memory and then to stream.

Deployment

A key development and design goal for XIL2 was to allow for easy deployment in a stock Jboss4 installation. To use the XIL2, you simply drop the xil2 jar file and xml deployment descriptor into the jboss deployment directory. Similarly, there is a single dll required (csil.dll) to connect a .Net client to the an XIL2 enabled server.

History

The CsIL project originated as an integration to JBossMQ3. The protocol base then was UIL, which has since been depracated in Jboss. The old CsIL code is still in cvs, but maintenance has been discontinued. The original CsIL pages is also available here.
