The Enterprise JavaBeans 3.0 core specification, Section 21.1.2, states:
|
|
</p>
|
|
|
|
<blockquote>
|
|
<p>
|
|
An enterprise bean must not attempt to listen on a socket, accept connections on a socket, or
|
|
use a socket for multicast.
|
|
</p>
|
|
<p>
|
|
The EJB architecture allows an enterprise bean instance to be a network socket client, but it does not
|
|
allow it to be a network server. Allowing the instance to become a network server would conflict with
|
|
the basic function of the enterprise bean—to serve the EJB clients.
|
|
</p>
