Hi Arnaud,
Thanks for your help. Your sample codes are really very useful to get
an idea. At this moment, I can fetch the following information
(decoded) from the broker by "management" queue bound on
"qpid.management" exchange.

I am wondering if you can give me a sample example to send message to
broker so that I can get the schema from broker. I have another queue
called "reply" bound on "amq.direct" with the routing key "reply" but
dont know how to get the management schema in it (cannt find the
example for sending the message to broker to fetch the management
information). I have read the qpid management notes and now know how
to fetch the schema (in theory) but it will be nice to see the sample.
It will also be nice if you can explain a little about management
interface you mentioned.
Also, if you can let me know where I can put my work?
Just to update you, I started working on a ppt file and on
documentation for this project.
Thanks in advance.
Best Regards,
Rahul
Rahul,
To get the schema from the broker, there are three protocol exchanges
you need to execute:
1) Request the list of schema packages.
2) For each package (or the package of interest), request the list of
classes.
3) For each class (or the class of interest), request the schema details.
To send protocol messages to the management broker, create the message
with AMQP types via the Java encoder/decoder, then send them to the
"qpid.management" exchange using "agent" as the routing key.
Replies will be transmitted according the the key in the replyTo field
of the message. Make sure the replyTo attribute is set on the message
(setJMSReplyTo) to amq.direct/reply.
Here are the protocol references (see
http://cwiki.apache.org/confluence/display/qpid/Management+Design+notes
for protocol details):
1) Request packages by sending a "Package Query" message. You will
receive a "Package Indication" message on your reply queue for each
package known to the broker. The "qpid" package contains classes for
the broker itself.
2) Request classes-per-package by sending a "Class Query" message. You
will receive a "Class Indication" message for each class in the
package. Note that a class is identified by the following tuple:
(package-name, class-name, class-hash). The hash is included because
there may be more than one version of the schema for a particular class.
3) To request the schema details for a class, send a "Schema Request"
message to the broker. A "Schema Response" message will be sent in
reply which contains the details of the class schema.
If you have further questions, don't hesitate to ask.
Regards,
