quartz-scheduler

问题 Does the following cron expression mean "execute every other Sunday?" 0 0 3 ? * 2/1 * I'm trying to use it with the Spring Quartz scheduler. 回答1: The expression you are asking about fires at 3 am Monday to Saturday. From the Quartz Javadoc you could try using the two expressions 0 0 3 ? * 1#1 * and 0 0 3 ? * 1#3 * to execute on the 1st and 3rd Sundays of the month. The D#N syntax lets you pick the Nth day D of the month. 回答2: No, I don't think so. I think "2/1" means "Tuesday through Sunday."

My application server is Websphere 8.0.0.1 and I already read that it is against the EE6 spec to make the name "java:" available to non managed threads. There are two solutions now I think: Let Websphere create the worker threads

问题 Well, I'm using Quartz to schedule some jobs that I need in my application. But, I need some way to access a Stateful SessionBean on my Job. I knew that I can't inject it with @EJB. Can anyone help me? Thanks. 回答1: I used the EJB3InvokerJob to invoke the methods of my EJB. Then I created my jobs that extends the EJB3InvokerJob, put the parameters of what EJB and method it should call and then call the super.execute(). The EJB3InvokerJob can be found here: http://jira.opensymphony.com/secure
