I need to create a set of data access components that are deployed to Jaguar
and retrieve data from various backend database.
Is it possible to create these components without the component being tied
to a datawindow and pibble? What tool do we use and how difficult would it
be for novice EAS developers?

Absolutely. Just as Tim said it can be done in a variety of things. If you
know PB and want to continue using that, no problem. You can pass data as
result sets, blobs, or whatever, CORBA supported data type that you want.

You can use Java and C++. Not hard if you know these languages.
To avoid .pbl? Do you really mean avoid powerbuilder? If you still want PB
then you will need .pbl/.pbd.
But in PB you don't need to use the HTMLDW you can deploy NVO and retrieve
the data there. Then build HTML or convert datastore result set to HTML and
return that. There are so many ways to do this that I don't have time to
cover them all.
Novice EAS developers? Does that imply novice PB developers? EAS/Jaguar
does not require much development effort. Dynamo is another story. This
gets into HTML/DHTML/JavaScript/CSS. But these skills are common to any WEB
development project no matter what tool you use. So EAS is not the issue.

Its all so terribly easy once you know how. :-)

If you use Powerbuilder for component development you sill have to create a
Java stub and then compile the component into a
Java class object. Why not just create the component in Java or C++ in the
first place. This would be fine if only HTML client
would be using the components. In our case, Powerbuilder clients also need
the components. Can a Powerbuilder datawindow
be based on a Java class object? How?

The next issue has to do with performance. We are planning to replace an
80x25 mainframe app with a browser based version.
I don't expect to reach the same speed as the mainframe app but I'd like to
get as close as possible. If we use Powerbuilder
we will be tied to a pibble. We would also be inserting an additional layer
of processing. [ Jaguar will open the pibble, get the datawindow source,
retrieve the data, then send it to dynamo ]

I'd like to hear more discussion and recommendations along these lines.....

You have a lot of things in this e-mail. I just want to comment on the stub
generation. You will always need a stud. Even if you use java or C or
PowerBuilder.

If you are looking for top performance you should look at using Java stubs
and use PowerDynamo or a Servlet engine on the web server.

Jaguar will give you the high availability you need to replace the
mainframe, but you will not match the speed. High probability you will
improve functionality.

[Jaguar will open the pibble, get the datawindow source,
> retrieve the data, then send it to dynamo ]

You don't have to use the HTMLDW. Use Java or C++ is OK. It depends on
what you want to do. Do you want to return data to a datawindow control in
PB client, use GetfullState and SetFullState, with a datastore.

PB datawindow based on Java or C++? Why? The SQL is in the DW object which
is in the .pbd. Not the control. Even if the datawindow were written in
LISP the dw object is separate from the control. So you have to "load" it.

I think you should sit down with someone and discuss exactly what you want
to do. There are a lot of variations to consider. And an optimal path, I'm
sure, lies in an EAS solution, if it lies anywhere.

E-mail me at tim.nesham@born.com if you'd like to get into more details
offline.
