<DT>public interface <B>EJBObject</B><DT>extends java.rmi.Remote</DL>
<P>
The EJBObject interface is extended by all enterprise Beans' remote
interfaces. An enterprise Bean's remote interface provides the remote
client view
of an EJB object. An enterprise Bean's remote interface defines
the business methods callable by a remote client.
<p> The remote interface must
extend the javax.ejb.EJBObject interface, and define the enterprise Bean
specific business methods.
<p> The enterprise Bean's remote interface is defined by the enterprise
Bean provider and implemented by the enterprise Bean container.
