Frank, I'm listening too. Goddard is a small college in Vermont and we are a tiny IS shop (me and a part time programmer on the administrative side and me and two staff to handle academic and PC stuff). Nevertheless we have continuously developed our administrative systems in-house after an intial purchase of an integrated package for the S/34 in 1981--moving on to a S/36, an AS/400 E10, and now our 600e with V4R2 and V4R3 waiting to install. So I know some RPG, but in later years we have relied on Progen for most new application work (it still generates RPG though). We have just completed the implementation of our Y2K compliant systems in October. Now we play! Like many of us, I suspect, we had to lay aside the GUI/Java stuff until Y2K was complete. (We had a brief month or two of distraction with GUI last Spring when the Development office threatened to jump to a windows application and we had to demonstrate graphical potential...) Now, my colleague Booth (who works three days a week) has resumed work on a next generation of applications using Visual Age RPG. Booth was able to make progress seemingly easier than I did when I wrote some Java JDBC code hitting the 400 using JBuilder last spring. After that I decided to join VADD and buy the IBM Java product. At the same time we invested in the VARPG product. Today, in fact, I am just starting to look into Java again, and downloaded V2. My plan is to carry on a two pronged attack on AS/400 GUI applications; let Booth pursue the VARPG path, while I see if I can do anything useful with Java. We would love to be able to provide secure browser based and controlled access to our AS/400 data, but Booth has already produced working applications with VRPG--which nevertheless require installation and the runtime library (I just bought a ReWriteable CD drive to make installation of the runtime library easier). Anyway, I am interested to hear if anyone else is also comparing or working with Visual Age RPG, and if, so, how it compares to Java. Other questions I have: Am I a fool to try to develop applications using AS/400 data with only Visual Age Java Professional, and not the Enterprise product? Does anyone on the list have the Enterprise edition? Are you VADD members? When I looked into V1 it seemed there was a dirth of examples; perhaps V2 is better. Can anyone point to the best source of examples? A basic question seems to be whether to try to use the Toolkit and record level access, which seems more like something an RPGer can get their teeth into (I just want to chain to that record!) or to use JDBC and the SQL model. We have never used SQL on the 400, but did purchase the IBM SQL product last June (another thing set aside until Y2K was complete). Last June I never had any success with IBM Java, while at least JDBC and JBuilder let me build an application that sort of worked, except, minor detail, it crashed a lot. Thanks for listening. I assume there must be more members of the list than respond, so, moderator David Gibbs, are you listening? How about telling us how many members are in the list. Does the list let us request a listing? Ravi Nielsen Director of Information Services Goddard College Plainfield, Vermont USA P.S. I'm emailing this from my personal business account, Maple Hill Software. We have been developing and selling software for handweavers for DOS and Windows since 1984. So my background includes knowledge of OOP through use Borland Pascal for Windows and later Delphi to develop our Windows weaving program. I'm also hoping that my knowledge of Windows and OOP will help reduce the learning curve with Java. > -----Original Message----- > From: firstname.lastname@example.org > [mailto:email@example.com]On Behalf Of DeSarro Frank > Sent: Monday, December 21, 1998 11:25 AM > To: firstname.lastname@example.org > Subject: Java questions > > > I have two questions.
