[jira] Commented: (TUSCANY-1497) Add full support for service references (which can be passed accross binding protocols)

["Jean-Sebastien Delfino (JIRA)" <tu...@ws.apache.org>]

    [ https://issues.apache.org/jira/browse/TUSCANY-1497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12516854 ] 

Jean-Sebastien Delfino commented on TUSCANY-1497:
-------------------------------------------------

I suggest that the service references should implement externalizable and serialize by default into a human readable form.

It should also have the ability to serialize to/from a URI and to/from a WS-addressing service endpoint reference.

Bindings should transport service references in an appropriate binding specific format (possible leveraging the service reference's builtin serialization capabilities), for example:

- Web Service binding -> serialize to a WS-addressing service endpoint reference, the target Web Service (possibly non SCA) should be able to use that EPR to call the SCA client back

- JMS binding -> properties of the JMS message

- EJB binding -> a valid reference to an EJB session bean? not sure about this one

etc.

It should be possible to pass a service reference to a remote service in the middle of other business data (a pretty common use case IMO). This will require some specific support from the various Tuscany databindings.

Another use case is: Get a service reference, store it into some persistent storage, stop the runtime, restart it the next day or next year, read the service reference back and use it to invoke some services, possibly within the scope of the same long running conversation if the service reference was conversational.

> The Java spec defines CallableReference and ServiceReference. At this moment, we only have limited support for local cases (keeping pointers to java objects). We need to support the marshaling/unmarshaling of service references accross binding protocols.
