[jira] Created: (QPID-101) Add Queue Browsing feature to Java client (AMQSession)

Add Queue Browsing feature to Java client (AMQSession)
------------------------------------------------------

                 Key: QPID-101
                 URL: http://issues.apache.org/jira/browse/QPID-101
             Project: Qpid
          Issue Type: Bug
          Components: Java Client
            Reporter: Marnie McCormack
             Fix For: M2


Currently attempts to create a QueueBroswer result in a UnsupportedOperationException being thrown. This needs to be corrected. (See AMQSession.createBrowser methods). 

Note that TopicSession and QueueSession implementations correctly thrown IllegalStateExceptiuon from these methods and do not need to be changed.

More info from JMS 1.1 Specification follows (see spec for more details):

5.9 QueueBrowser

A client uses a QueueBrowser to look at messages on a queue without removing
them. A QueueBrowser can be created from a Session or a QueueSession.
The browse methods return a java.util.Enumeration that is used to scan the
queue's messages. It may be an enumeration of the entire content of a queue,
or it may contain only the messages matching a message selector.
Messages may be arriving and expiring while the scan is done. JMS does not
require the content of an enumeration to be a static snapshot of queue content.
Whether these changes are visible or not depends on the JMS provider.

Re: [jira] Commented: (QPID-101) Add Queue Browsing feature to Java client (AMQSession)

Posted by John O'Hara <jo...@gmail.com>.

There are so many things to do.
What's driving the urgency?  Is it an M2/M3/M4 thing?  Why?

Queue browsing is needed for the TCK, and handy for management interfaces,
but is seldom used in actual applications.  The apps we have don't need
this, so I'd like to make it less urgent.

Obviously we need to pass the TCK and be fully JMS compliant, but we can't
do everything at once (can we?).

AMQP also needs a browse interface added to the protocol.  I'd expect this
in the v0-10, in Q1.  In the meantime it could be implemented as an Qpid
specific feature, but do we need it *that* much.  Will end of Q1 do?
