NEW ISSUE: Missing normative statements for binding.jca inboundOperation

[Simon Holdsworth <simon_holdsworth@uk.ibm.com>]

TARGET: SCA JCA Binding Specification
CD-03

DESCRIPTION: 

The following attributes of binding.jca
have defined behaviour, but no normative statements:

/binding.jca/inboundOperation/@name
-  nothing normative to say that this must match the name of an operation
in the interface (although that's the same as with the JMS binding)
/binding.jca/inboundOperation/@nativeOperation
- nothing normative to say that this needs to be unique within this binding
instance (cf. JMS binding selectedOperation and note different naming).
 Also no normative rules about the relationship between the nativeOperation
and the values returned by the operationSelector.

PROPOSAL:

Rename the nativeOperation attribute
to "selectedOperation" to be consistent with binding.jms and
the operation selector.

Add the following to the definition
of the binding.jca/ inboundInteraction/inboundOperation/operation/@name
 attribute: 

The value of the inboundInteraction/inboundOperation/operation/@name
attribute MUST match the name of one of the operations in the containing
service's or reference's interface. [BJC200XX]

Add the following to the definition
of the binding.jca/ inboundInteraction/inboundOperation/operation/@selectedOperation
 attribute: 

The value of the inboundInteraction/inboundOperation/operation/@selectedOperation
attribute MUST be unique across the inboundInteraction element. [BJC200XX]

Add to section 4 "Operation Selectors
and Wire Formats":

When a service with a JCA binding receives
a message, the SCA runtime resolves the name of the operation in the service's
interface that is to be invoked by using the operationSelector and inboundInteraction
elements defined for the binding. The resolved operation name is defined
as follows: 
•        If
the selected operation name generated by the operationSelector matches
the value of an inboundInteraction/inboundOperation/@selectedOperation
attribute then the resolved operation name is the value of the inboundInteraction/inboundOperation/@name
attribute. 
•        Otherwise
the resolved operation name is the selected operation name generated by
the operationSelector.
When a message is received at an SCA
service with JCA binding, the SCA runtime MUST invoke the target component
using the resolved operation name [BJC400XX].
When a message is received at an SCA
service with JCA binding and the resolved operation name is not in the
target component's interface the SCA runtime MUST raise an error [BJM400XX].
