Re: Pete's web5250 was->Re: Business Developers was ->Re: IBM Gives RPG Devotees Their Own Café -- WEB400

Very cool! Just when I thought I was going to be watching "The Office" tonight it looks like I will be pounding through this code - btw, thanks for posting the code as that will bring a lot of fruit to the discussion IMO.

Question: So this is obviously using the different fairly direct correlation of 5250 ui components to html ui components (i.e. text field to <input>, etc), but what would be an approach for wanting to render a drop down box as these screens would be based on a DSPF DDS? The one thing that comes to mind is simply having an "indicator" in the stream that would tell a custom ExtJS script to render the data elements as a drop down and also specify how to map the data to the correct input field when it gets back to the server.

Re: IBM Gives RPG Devotees Their Own Café

Gents;

Just to follow up on my idea before Christmas. – to build a JSON AJAX
client for 5250 data.

I have made a simple running prototype so I’m convinced it can be done.

This tiny emulator demo is written 100% in RPGLE, and can be used as
workstation scripting screen scraper prototype.

The current version is simply is using plain HTML, but the real goal -
a more fancy JSON / AJAX providing data for JavaFX or just javaScript
will be super simple to implement.

The prototype is fare from stable and lot of stuff to be done, but you
can give it a try it on:

http://icebreak.org:60000/icecap04.aspx

Login with user: DEMO and password: DEMO – You need to type in
UPPERCASE

… please don’t do anything stupid while you logged on .

The source is available at:

http://demo.icebreak.org/webfiles/icebreak/iceCap.zip

The iceCap.zip contains the following:

iceCap.rpgle.h The prototypes for the client

iceCap04.aspx This is the tiny emulator
implementation
written in RPGLE for IceBreak

scv242.c The iceCap API module that
deals
with all the ugly 5250 stuff

vtTrace.txt A JSON log of a simple session
login
on, CFGTCP etc.

I have used IceBreak as the server (I’m a little biased here) but I
have made the iceCap API reentrant so it can be ported to CGIDEV2 if
anyone will be interested …

The code is a monolith – I know – it’s a prototype – don’t complain…
