Thanks Jon. That is some interesting input. I must confess that I have not done any socket programming, and so it did not readily come to mind. If you assume that the client can talk data queues (hmm, what could that be? :-D) are there advantages/disadvantages to using sockets locally or remotely? I take it that you agree with the concept; that is comforting. Do you have any pointers or resources that would be of benefit in implementing such an architecture on the AS/400 (like somebody that has done it and wants to give away the code)? Ideally I would like to avoid writing my own application server of course. That is why CORBA, LDAP, or something similar would be of considerable interest, remembering that I am not able to lock the host based version into a very recent (modern) release though. It appears to me that I am destined to write whatever service abstraction layer I require. More input? Any nay sayers? -Andrew Goodspeed London Bridge Group Norcross, GA USA Jon.Paris@halinfo.it on 03/21/2000 07:46:21 PM Please respond to JAVA400-L@midrange.com To: JAVA400-L@midrange.com cc: (bcc: Andrew Goodspeed/Atlanta/LBSS) Subject: Re: N-tier design >> that seems to whittle it right down to data queues...... Am I way off on this? Who has two cents to add? Any reason why sockets wasn't on the list? Java does it real well and real easy - It is on most any release of AS/400 you'd want to run on and can be accessed directly from RPG if there are no C coders handy. I would have thought that these days it was the natural choice. Data Queues force you to work with a client that can talk data queues - why restrict it like that? +--- | This is the JAVA/400 Mailing List! | To submit a new message, send your mail to JAVA400-L@midrange.com. | To subscribe to this list send email to JAVA400-L-SUB@midrange.com. | To unsubscribe from this list send email to JAVA400-L-UNSUB@midrange.com. | Questions should be directed to the list owner: email@example.com +---
