Re: Web5250 Business Developers was ->Re: IBM Gives RPG Devotees Their Own Café

I have a customer that something like this would be perfect for. They have been struggling through CGIDEV2 for awhile and going "back to the basics" of green screen type programming while still getting a browser presence would probably fit the ticket perfectly. I would have to make some changes first like not having them start on the OS400 login page and instead allow them to run programs under a generic profile until they were ready to sign in, but I don't think that would be too hard. I would also play with the css some to give it a more "web 2.0" look (to please the insurance agents that would be using it). There are only about 50 to 60 users that would be using this 5250 web application on a spankin new 520 with 4GB of memory - would be interesting to see if the load was too much if ran under Tomcat.

Pete, did the menu system you created have similar needs to the approach I described?

I haven't tried to "scale" it. It would probably be similar to having tn5250j on the desktop with many sessions open. Haven't looked into the internals of 5250j to see if there are limits. Probably should take a look at the "expense" of each connection. I only have to deal with one object in tn5250j, the 5250 protocol bean, all of the other stuff I am insulated from so it might take some digging to unpack all of the issues.

Much of this was written early on in the AEE development cycle Nathan. We eventually settled on using the tn5250j applet because it was more stable and complete. I saw Joe's post about PSC and I wonder if something very similar to web5250 could be written in RPG. It would probably be something worth investigating. The biggest issues I had were with function keys that triggered browser functions, rather than the 5250 functions but I was a complete noob with Java, Javascript and css (which could be helpful) so there are probably better approaches I could take now. I need to blow the dust off of this I guess. I haven't had much interest in the project although I get a connection or two under the Demo userid every week.
