Re: From RGP to ¿Java?

By far the fastest and easiest way to create web applications is to use EGL. I just did a demonstration in Raleigh where I create an entire multi-tiered application, including both thin-client JSF and rich client, in under an hour. The application displayed an array of customers in a grid, and called an RPG program to get the data.

Most of the scripting technologies can get you a "decent" page in thin client. The trouble comes when you want something modern. If you're going to go through all the effort of creating a modernized interface, you need something that uses a framework like jQuery or Dojo. With EGL, you can create a thin client interface in literally minutes. You can also expose an EGL function as a web service with a few clicks. The beauty of the language comes when you want to do rich client. EGL Rich UI is pretty hard to beat.

You can see some information about it here:

IBM Rich UI has a decent set of widgets, but more importantly it's very easy to extend to use other frameworks. As an example, here's a dashboard I mocked up in a couple of hours using Dojo:

Took about 70 lines of code; I'm writing an article about it for Search/400.

I can attach this to back end logic and have the entire thing up and running in a day or two, using a WYSIWYG editor to put the pieces together. I don't think there's another tool that you can get that will do this. And the final huge benefit? The tooling used to develop this little project (RDi-SOA) will also let you maintain and debug the RPG back end.

i have a business aplication developed with RPGIV (also using CL, PRT, PF and DSP) and now I need to modernise the aplication.
If you done the same, please comment your experience.
I've tinked rewrite the application in Java or Python?
What graphic interface?
