Looking at the JIRAs, and based on the experience of supporting the current client, the two areas where it causes most problems are 1) failover and 2) addressing. For both (but especially failover) I think we need a very clear understanding of the functionality we are looking for the client to provide before we can decide which layer it is best placed in. If the functionality is likely to be common across the JMS and Qpid APIs then it would seem sensible not to write this code directly into the JMS layer. Before we start cutting any code I think we need general agreement in the Qpid Java community about the functionality that is required and where it is going to be implemented (and ideally we should also be coordinating by whom it is going to be implemented also :-) ). -- Rob > I would love to hear everybody's thoughts on this. > More importantly it's good if we could also discuss on a plan and set > some milestones to ensure we stay focused. > > Personally I would love to see a reasonably working prototype by 0.22. > If we can get something going for 0.20 that would be a bonus, even if > it's just experimental (preferably on a branch) and Alpha quality. > > I mentioned the above milestones to kick start the discussion and get > things rolling. > We could start on a branch and then move it to trunk during 0.22 if > everybody is satisfied with the progress. > > Regards, > > Rajith > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org > For additional commands, e-mail: dev-h...@qpid.apache.org > >
