Hello All,

previously we used quartz and org.quartz.StatefulJob to make sure that a scheduled method will not be invoked if the previous method didn't complete it's work.

is there a way to achieve the same behavior when using EJB3.1 and @Schedule?

I tried to play with -
1. getting the handle at the beginning of the method
2. canceling the timer
3. executing the BL
4. requesting the handle from the timer

this is based on  http://docs.oracle.com/javaee/6/tutorial/doc/bnboy.html http://docs.oracle.com/javaee/6/tutorial/doc/bnboy.html

but i get many errors (running on jboss-as-7.1.0.CR1b)

does any one know if there is a way to do the above scenario?
