24 * In Jgroup, an <i>external remote interface</i> is an interface that
25 * declare a set of methods implemented by an object group that may be
26 * invoked from a remote Java virtual machine. An external remote
27 * interface must satisfy the following conditions:
28 *
29 * <UL>
30 * <LI>It must at least extend, either directly or indirectly, the
31 * interface <code>ExternalGMIListener</code>. </LI>
32 * <LI>Each remote method declaration in the external remote interface
33 * must include the exception <code>java.rmi.RemoteException</code> in
34 * its <i>throws</i> clause, in addition to any application-specific
35 * exceptions (note that application-specific exceptions do not have to
36 * extend <code>java.rmi.RemoteException</code>). </LI>
37 * </UL>
38 *
39 * The <code>ExternalGMIListener</code> is a marker interface that
40 * declares no methods.
