RE: Expanding SocketServer

[Aaron Smuts]

Ya, the difference is important, but my point is irrelevant here anyway, sonce the ejb itself won't be doing any network io.  That clients sockets are permitted is soewhat strange though, since file io is discouraged. . . .

Aaron,

 

Are you sure about that?  I thought you couldn't open server sockets, but client sockets were okay:

 

From the EJB spec (page 491-492 of EJB 2.0):

The file system APIs are not well-suited for business components to access data. Business components should use a resource manager API, such as JDBC, to store data.

• An enterprise bean must not attempt to listen on a socket, accept connections on a socket, or use a socket for multicast.

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.
