The tests are failing with:
javax.naming.NameNotFoundException: remote not bound

when doing a lookup:
Object ref = ctx.lookup("refs/StatelessBean2/remote");

The EJB is annotated with:
@Stateless(mappedName="refs/ejbs2/StatelessBean")

Lookup should be changed to:
Object ref = ctx.lookup("refs/ejbs2/StatelessBean");
