Well the plan is to have this included in one of the first point releases of Seam (eg: Seam 3.0.1). In the meantime you should be able to check it out from https://github.com/seam/cron, “mvn install” and include it in your pom.xml.

Unfortunately the Scheduling module still hasn’t made its way out of the ‘sandbox’ so I don’t think it will get pushed to the JBoss maven repo any time soon. Your best bet is still to build from source using Maven3, as you’ve probably already been doing:
svn co \ http://svn.jboss.org/repos/seam/sandbox/modules/scheduling/trunk cd scheduling/ mvn clean install

Nice work! Will this ever make it into any official package? Is there a maven repo for this or would you consider pushing it out to the central maven repo?

Yes it’s all sourced from static configuration at the moment. But since the Environment Configuration module exports config data to JNDI, I guess it would be trivial for Scheduling to support it by simply checking for named schedules in JNDI first and then falling through to scheduling.properties. Or perhaps also checking for an entry which points to a scheduling.properties file arbitrarily located on the filesystem.

WRT delayed execution, the API could look like this:

@Delayed(minutes=20) public void doThisLater(User user) { ... }

or like this:

public void doThisLater(@Observes @Delayed(minutes=20) AppEvent event) { ... }

… but I’m not sure how I’d go about implementing that yet. Also I’ll have to check out asynchronous events in the spec for any possible overlap.

I love this notation — combining the scheduling with CDI’s event system, but it seems that what I see here is driven from a static schedule — ‘every hour’, ‘after hours’, or something based on cron… do you plan to provide a way to schedule something dynamically? In other words, ‘a user just took some action, let’s schedule something to fire 20 minutes from now’?

Also, I’m a big believer in being able to configure your application from outside of a packaged .war or .ear file — any plans to support this capability?
