Re: [Jcyclone-users] a few questions

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

Alex,

Unfortunately, i don't know of any simple writeup on how to get
started with JCyclone.
If you want a basic example of how to setup JCyclone, there's a very
simple example of a file config-based setup with 3 stages and one
input plugin in the core/test/org/jcyclone/core/fileconfig directory.
The core/test/config/fileconfig-jcyclone.cfg describes how the system
is setup. Basically, you have 3 stages: Initial --> Middle --> Last,
and they send messages through and the test verifies that the message
comes out.
The plugin in this example is not actually used.

If you wnat a more substantial example, feel free to take a look at
version 0.1.4 of our product, the Marketcetera Platform. (we have
moved from JCyclone to the embedded ActiveMQ setup which is not
something you are interested in).
You can check out tag 0.1.4 with:
 svn co http://svn.marketcetera.org/platform/tags/0.1.4/ platform-014

If you look at the code in
core/src/main/java/org/marketcetera/jcyclone/ you'll see all the base
classes, and then you can see the underlying implementations and usage
in oms/src/main/java/org/marketcetera/oms
(you can also browse it all at
http://trac.marketcetera.org/trac.fcgi/browser/platform/tags/0.1.4/core/src/main/java/org/marketcetera/jcyclone/)

I'm attaching a class diagram of how we setup JCyclone, and you can
also look at
http://repo.marketcetera.org/images/screenshots/oms-overview.png
for a more high-level view of how the stages are setup.

We use a flat-text-file (not xml) format to setup the JCyclone stages,
you can see how everything is wired in the
http://trac.marketcetera.org/trac.fcgi/browser/platform/tags/0.1.4/oms/src/main/resources/oms.properties#L28
 file.

Hope this helps. Feel free to ask any follow-up questions.
