RE: Support for asynchronous non-blocking calls available in the sandbox
Jean, I am not sure what state is this in now. I have been working on a spaces binding for asynchronous calls. I am also interested in looking at JMS binding. I would appreciate it, if you could please share your thoughts on this. Thanks Meeraj -Original Message- From: Jean-Sebastien Delfino [mailto:[EMAIL PROTECTED] Sent: 25 April 2006 16:39 To: tuscany-dev@ws.apache.org Subject: Support for asynchronous non-blocking calls available in the sandbox I checked a first implementation of support for async non-blocking calls in the sandbox. Directory sandbox/sebastien/java/sca/async contains the runtime code, sandbox/sebastien/java/samples/helloworldasync contains an asynchronous variation of the helloworld sample. More details about how this code works are in http://issues.apache.org/jira/browse/TUSCANY-223. Could people in the group please take a look and see if you're (reasonably) happy with this initial implementation? If there's no objection I'd like to move this to the sca/core project in the next couple of days. There are still some limitations and temporary workarounds in this code, I'm probably going to need help to go from there and improve this initial implementation. I'm also looking for a better sample than helloworld to demonstrate the async capability...

Re: Support for asynchronous non-blocking calls available in the sandbox
Yes, I can make it to the chat, talk to you then. I'm not planning to be at JavaOne, I'm afraid. - Original Message - Cool. I have some work on a BigBank async sample done as part of the specification collaboration that I need to clear but once I do, we can discuss that as part of this topic. The scope containers may need to be refactored slightly (we can discuss) as well as I believe there may need to be a slight change in the spec regarding the way conversations and scopes are defined. We've started to go over this in the spec group already. Perhaps we could schedule a time to discuss on IRC so others interested may join in? We have a weekly IRC chat at 8.30PST on Mondays. We could bring this up then initially if you can make it. does that time work? If not, we could perhaps schedule another time? Also, any plans to be in the Bay area for JavaOne or at the Tuscany BoF?

The idea is to use it to test (in addition to the simple non-blocking call of the customer by the shipper) features like callbacks, passing references to call, and references with multiplicity *..n (as in a retailer with several warehouses to choose from) when they are available. For now it is just a straight chain with a hardwired reference from the shipper to the customer, and using a dummy order (which can also become more realistic, using an sdo, for instance). I'll keep working on adding the features that are available. I can send the zip file to Jean-Sebastien to add to the sandbox. Ignacio [snip] Great! Thanks for volunteering. We have an async variation of the helloworld sample under samples/helloworld/helloworldasync, but I'm not too happy with it as it's not very realistic. So any idea of a better sample to demonstrate the async programming model is welcome! We're just at the beginning of our async implementation so it's the right time to hop in, and help us improve it :) Thanks -- Jean-Sebastien [snip]

great. I'll take a look today and tomorrow. I'm also interested in helping so let me know what you would like done.
