Subject: Proposed resolution for issue BINDINGS-97

My proposal to resolve this issue is as follows:

The raiser is correct in stating that section 6.2 does not say how the correlation Id is set in request messages.  We don't need to specify anything particular about the correlation Id for this case. We should just remove the reference to correlation ID from BJM60017:

For an SCA service with a JMS binding, when a callback request message is sent the SCA runtime MUST set the JMSReplyTo destination in the callback request message as defined in sections 6.1 or 6.2 as appropriate for the type of the callback operation invoked [BJM60017].

The only remaining concern is whether there is any relationship between the original forward request correlation and any callback correlation.  We could consider adding a statement to section 6.4.2 to this effect, however if we decided to add conversation support back in, this statement could then be incorrect, so my preference is just to stick to defining the required behaviour as per the current and modified normative statements.

In terms of the response to the public review comment, I would propose we respond as follows:

"You are correct that the reference to correlation Id in statement BJM60017 is confusing.  There is no relationship defined by the JMS binding specification between the correlation Id used for forward messages and those used for callback messages.  We have removed the reference to correlation Id from BJM60017."
