The program violates the Enterprise JavaBeans (EJB)
specification by using sockets.
Extended Description
The Enterprise JavaBeans specification requires that every bean provider
follow a set of programming guidelines designed to ensure that the bean will
be portable and behave consistently in any EJB container. In this case, the
program violates the following EJB guideline: "An enterprise bean must not
attempt to listen on a socket, accept connections on a socket, or use a
socket for multicast." The specification justifies this requirement in the
following way: "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."
