Your problem is not a part of EJB or whatever specification. Having a thread deleting rows while another list the rows is a business problem.
The whole solution for handling that is a combination of transaction, reentrance and lock mechanism. The lock mechanism is not a part of EJB spec, but application servers can do that. You can also write a portable lock mechanism, which is decribed at the location: [url] http://www.javaworld.com/javaworld/jw-07-2001/jw-0713-optimism.html [/url] I hope this helps you.
