CGI - Pros: You probably already know RPG. Easy to start with. CGI - Cons: Doesn't always scale well. Locks you into using iSeries as your webserver and as your back-end. HTTP server and web application must be in same tier. Tough to hire people that know anything about RPG-CGI. JSP Pros: Easy to find people who know it. Can run web app tier on just about any platform. Can connect to multiple back-end databases. Can separate HTTP server tier from web app tier. Lots of open-source resources. JSP Cons: You probably don't know it. Can be tough to get started if you don't have an experienced Java person. I was lucky. We had a kid with a CompSci major working on our help desk, just dying to get into development. Once I got the OK to start playing with WAS, I also got him put on my team. He wrote a bunch of classes to mask the difficulty of doing things like connecting to a back-end database. He also figured out how to get WDSC working and get the test server communicating with the back-end (no mean feat). So for folks like me (lots of HTML, but not much Java), it was really easy to start developing. I wouldn't think of what I'm writing as Java; it's more like Decaf. But I can run queries and call RPG and CL programs as stored procedures, almost like I know what I'm doing. Once you get the hang of how servlets and JSPs interact, and how to pass data from a servlet to a JSP, it's really a piece of cake. And I think it's easier to keep your model, view and controller separate with servlets and JSPs than it is with a scripting language like Net.Data or PHP (where most of my experience was). If you have someone who knows Java, or can find someone who knows Java, I would recommend going that route. If not, I might recommend PHP over RPG-CGI, just because it will be easier to find people to develop in it. Mike E. On 5/12/06, Shane_Cessna@xxxxxxx <Shane_Cessna@xxxxxxx> wrote:
Can I get everyone's opinion on what the pros & cons are of using CGI RPGLE applications versus JSPs... I'm doing a little bit of CGI development and was wanting to get into JSP development just to expand my horizons a bit... Also, does anyone know of any good tutorials on getting started using JSPs to access 400 data?... Thanks in advance... Shane Cessna Senior iSeries Programmer North American Lighting, Inc.
