I am looking for a Java spreadsheet applet that includes basic functions such as simple numeric operations, cell references and support for simple formulas (i.e. sum and average). I would like a high quality (this means a real spreadsheet, NOT FREEWARE QUALITY) implementation and require source code and the ability to distribute freely. If you have any suggestions of who to contact for such an applet, I'd appreciate email at hberman@ltg.com or a response here.TIA,Howard Bermanhberman@ltg.com

You already said it : www.visualcomp.com! You can read at the press releases that thay announced in October last year that they will be making a version of Formula One/Java. They expect the beta to be available somewhere in the first quarter of 1997.

jpzwarte> You already said it : www.visualcomp.com!Their ActiveX/Plugin is excellent; I was looking for a spreadsheet like this in Java now. January 1998 is too long to wait.

There are two that I have experience with:

Rogue Wave's JWidgets Class Library has a spreadsheet widget
KLG's JClass Live Table Pro

Both support most numeric type activities needed by a spreadsheet and allow you to extend upon them by writing your own code for a cell or set of cells.  The learning curve on the RogueWave widget is quite steep but it seems to be the most powerful of the two.  I have recently used Live Table Pro on a project.  It breaks down in its event modelling when you start imbedding other components in it like drop-down lists etc.  It is a bit buggy on that count.  However, if you don't need to embed complex components inside your spreadsheet cells you should be fine.

I have prior experience with Rogue Wave as a company and their products have always been solid.  However, reaching them for support at times can be a hassle, in my experience.  KLG is a newer company that seems to have a good sense of market need as well.  Check out both their web sites where they have the tools for review and demos on-line.
