Re: [Jcyclone-users] Jcyclone - RIP ?

[Toli K. <to...@ma...>]

Anthony,

We've been using JCyclone for about 6 months now, and it does a great
job of fulfilling our needs.
We are developing an open-source financial trading platform
(http://www.marketcetera.org), and we use JCyclone as the
communication backbone for routing orders through the different stages
of the system.

JCyclone is 100% pure java and thus OS-independent. We have it running
on Windows, Linux and MacOSX without any issues.

We found the project to be fairly complete and stable, and we fixed
the bugs that we found.
We've implemented a new scheduler  based on java.util.concurrency
classes which provides a basic implementation of the system using
built-in concurrency.

As far as other projects, there's MuleSource
(http://www.mulesource.org) which implements  JCyclone features as a
subset of a much larger and more complex enterprise-service bus
platform.

Hope this helps. Since we are both writing financial products, I'd be
very interested in your findings and your evaluation of this space as
well.
