Java EE (Java Enterprise Edition) General Discussion

Hi,

I have seen some of the previous threads about calling the Thread.sleep() within an EJB. They all seem to say that its a bad idea to do so.

But since Sateless Session Beans (and MDBs) are not passivated, I dont see why calling a Thread.sleep() would be harmful ?

I need to make a method in an MDB to keep checking the DB for an event at regular intervals. And to reduce the DB-lookup overhead, I I have to use Thread.sleep() between the DB-lookups.

So, Is calling Thread.sleep() is a bad idea (i.e in a MDB or stateless bean)?

Thanks.
