Thanks Simon:
I'm sorry that I've ignored the Core documentation link before I posted my question. The layout of the apache myfaces orchestra page let me puzzle, I think the core documentation was belonged the myfaces, so I ignored it. Now, I have configure the orchestra successfully, but I test it and found it's no useful for conversation of manage bean, every times, it's always invoke the backing bean's constructor method when I clicked trinidad table to post my request on the same page, and my understand is that only first time will invoke the constuctor method, if I execute other's function in the same page, only related method will be invoke in the same conversation. Is this correct understanding for conversation scope? And is this a bug of trinidad? Could you give me more advise?

Best regards,
Palvin

Have you read this page?

http://myfaces.apache.org/orchestra/myfaces-orchestra-core/installation.html

There is an example webapp. Not all of it works unfortunately, but the
simpler examples do. See the "Project Information | Source Repository"
section of the orchestra examples project homepage:

http://myfaces.apache.org/orchestra/myfaces-orchestra-examples-project/index.html

If you have any more questions about Orchestra, please put [Orchestra]
in the subject line of your email (I've fixed this reply). Putting
[myfaces] there isn't very useful, as we know this is about myfaces - it
was sent to the myfaces email list :-)

Oh and by the way, you need the orchestra-core jarfile in your project
to use orchestra. The orchestra-core15 package is just a few "optional
extras" for java1.5 users.
