RE: New GUI for green on black...

[nimrod@xxxxxxxxxx]

Hi Chris,

While my e-mail identity may make me a prime suspect, let me try and help
anyway.

First of all, the "expensive" middleware products may eventually be
inexpensive.  The determining factor is the amount and complexity of work
you need.  And not just now - in the long run as well.  What might seem
"inexpensive" may turn out "cheap", because you may have to pay the price
in labour, maintenance, support, lack of features, etc.

If you still think that your choice is the right one for you, then can you
elaborate some more on what control you need over the datastream?

As for OHIO, If my memory serves me right it was designed by Attachmate
(or another emulation vendor) as an "OO"-like version of EHLLAPI (which,
to give you my $.02, should not have survived the introduction of Windows
& OS/2, but technologies have an interesting survival pattern.....).

But the bottom line is still - I suggest you take a serious look into the
future, and then choose your strategy, rather than try to slam in some
quick & dirty solution.

Nimrod

KJP,

Thanks for your answer.

TN5250j isn't really of any interest to me. For our customers if we're
going
to do a thick client application I can assume that the user will have a
5250
emulator already, (normally Client Access).

os-ohio is of more interest, but the sourceforge site doesn't give any
more
information - theres no homepage. Incidentaly, where does the info on OHIO
itself come from, I can't find any on the IBM website. What's the
difference
(if any) between OHIO & HACL?

Chris.

Hello Chris

If you want control over the 5250 data stream there is a project on
sourceforge http://sourcforge.net/projects/os-ohio.  It is in java and does
not have an HTML interface but the html can be generated.

os-ohio is an Open Source implementation of the Open Host Interface
Objects
for java from IBM.

You might want to give it a try but like I said it does create HTML but it
does fit the non expensive middle ware requirement.

As far as an in-expensive (Open Source) fat java client that can produce
gui
screens you can try http://sourcforge.net/projects/tn5250j.  It has gotten
good response in the past couple of months for the gui parts.

Hope these help.

Regards

Kenneth
