Subject: RE: [wsrp] WSRP Publish, Find & Bind Presentation for F2F
Eilon, yes, if a producer offers multiple entities like a whether portlet and a stock ticker portlet both would be published as services to UDDI. The common access point is meant as the <wsdlsoap:address location="URL"> element within a <port> element. It is required to be common for session handling between differen factors. Assume a producer that exposes two factors like the WSRP 'base' factor and the 'properties' factor. Each factor would be represented as <portType> in WSDL sense. You then need two bindings - one for each portType (for example soap-rpc for both). Your service would then have two <port> elements, each port referencing one of the bindings. To allow a session state to be maintained between calls to both factors you need one common access point. Another scenario would be if a service exposed one interface, say the WSRP 'base' interface and then allow two bindings to it like soap-rpc or soap-rpc encapsulated in DIME. This would also result in two ports. This topic is currently under discussion in the calls. We have to figure out if we are allowed (WSDL spec for example) to share information between ports and if this is implementable. It may hit the factoring discussion.

Does this mean that if a producer has a weather portlet and a stock ticker portlet, these will be two services in the WSDL sense? There will only be one common access point for all ports (required for consistent session handling) What does access point mean? Does this mean that the producer cannot, for example, use one URL (or servlet) for certain operations and another URL for other operations? If that is the case, why is that so and how is that being enforced?

(See attached file: F2f-PFB-V0.2.ppt) For time constraints, we need to keep the discussion on this topic at the F2F relatively brief, so I'd like to ask everybody to review the presentation and what's written about Publish, Find, Bind in the WSRP 0.5 spec draft and raise any questions on the Publish, Find, Bind mailing list in advance of the F2F meeting. Also, please let me know of any issues that you think require discussion at the F2F in advance so that I can plan and adjust the slots appropriately. I want to collect all discussion points by Thursday this week. Best regards, Thomas
