             Bug #: 51419
           Summary: JMS Subscriber: using Selectors
           Product: JMeter
           Version: 2.4
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Main
        AssignedTo: notifications@jakarta.apache.org
        ReportedBy: slavko_h@yahoo.com
    Classification: Unclassified


The current implementation does not support to get a JMS message from a queue
by its property.

It could be implemented by adding simple "Selectors" item right after
"Destination" item.

In this case User could add "JMSType = `car' AND color = `blue' AND weight >
2500" for instance.

Below are some requirements from JMS standards:

A JMS message selector allows a client to specify by message header the
messages it's interested in. Only messages whose headers match the selector are
delivered. The semantics of not delivered differ a bit depending on the
MessageConsumer being used (see QueueReceiver and TopicSubscriber). 

Message selectors cannot reference message body values. 

A message selector matches a message when the selector evaluates to true when
the message's header field and property values are substituted for their
corresponding identifiers in the selector. 

A message selector is a String, whose syntax is based on a subset of the SQL92
conditional expression syntax.
