screen programming for the iseries?

screen programming for the iseries?
Sat, 2 Feb 2008 17:00:30 -0500
Not sure if this is the right forum but here goes ... What does one need to 
do to write screens for the green-screen iseries. Can this be done using 
pure Java?

Traditionally, green  screens are described by DDS and driven by RPG or 
Cobol programs.  You can also describe them with UIM and driver them by RPG 
or Cobol.  RPG is a better match.

There is also DSM (I think that's it), an API which allows you to read/write 
directly to the screen.  I suppose in theory you could manage this in Java, 
but I've never heard of it being done.

Check out the iSeries info center.  A search there may help:

Remember IBM green screen are block mode terminal, quite unlike what you 
find in the Unix world.

Sounds good, what happens to the IBM Roadmap? it says JAVA in the end. 
Wondering if their plans to make this available any time in the future.

Agree but Java programmers who are used to the object oriented mouse 
clicking world its a very steep curve to learn COBOL/RPG. Guess someone 
should put this on IBM's wish-list.

Java and the IBM roadmap.  Yes...  Not sure what IBM had in mind.  Probably 
two approaches:
1) Thick Java client using iSeries as a database server.  You may be 
familiar with Visual Age for Java, now defunct as a separate product, but 
living on somewhat in WDSC.  The native connectivity back to the iSeries is 
the toolbox, JT400.JAR.  SQL is another.
2) Web facing, which takes DDS described screen and converts them in Java 
that runs in a browser.  Very easy to do using WDSC, bit more difficult if 
you want to jazz up the interface.  Still  have RPG or Cobol driving the 
process, though.

Yes, it might be a stretch go get Java developers to write in RPG or Cobol.
