[seam-dev] [weld-dev] Next steps

[Peter Royle]

There's also the Scheduling extension which currently lives in the seam modules sandbox. I guess it's a Seam PE as it drags in other dependencies (ie Quartz), but it does work with plain Weld (well, at least in SE). For details and an example that's not in the JBoss repos: http://screamingcoder.com/life/2009/07/23/scheduling-in-web-beans-and-jsr-299-apps/
