For what it's worth...

After having played with a small example where a Java GUI uses
JavaTelnet to launch and control QUERY for accessing the TurboIMAGE
database MUSIC (from imsql.sampledb.sys), I have created a somewhat
larger example, this time using a custom NMPRG on the server side.

I chose Transact/iX because it is so convenient (and powerful) for
direct access to TurboIMAGE, but it should not be a major problem
to implement the server side code in another language (Pascal, COBOL,
Fortran, Basic, SPL, RPG...) as long as it can do TurboIMAGE access
and simple prompt-and-response terminal I/O.

You can find source code and screen shots at

Feel free (or encouraged) to contribute enhancements to the example;
it currently only allows browsing the COMPOSERS and ALBUMS master sets
(with add/modify/delete option).

Oh, and the example is currently only implemented as standalone Java
client program. Anybody feeling inclined to convert it to applet or
servlet? (The former will probably be a minor effort, the latter needs
some more work to design the HTML forms and sequence).

Lars.
