It has been very popular in the past, and remains reasonably popular as 
a toolset to enhance Java Swing applications.

The problem is, not many people are writing Java Swing applications. 
And those that do, tend to stick to the basic Swing toolset.

You need to decide if the tools offered in JClass are tools that you 
need.  If they are, then buy/upgrade them.  The JClass stuff has been 
around since 1997 (KL Group, bought by Sitraka, bought by Quest).  It's 
the most mature of the available tools, so I don't think you'll have too 
many problems with it.

Lori,
Thank you very much for your response.

We already are using it -- and we are having *lots* of problems
with it. We are mainly using the "livetable"

http://www.quest.com/jclass/livetable.asp

the "elements"

http://www.quest.com/jclass/elements.asp

and the "field"

http://www.quest.com/jclass/field.asp

According to the data on those Web pages, they haven't been
updated for nearly one year! And the "field" Web page shows a
screen shot that proudly boasts

"currently no equivalent in JDK 1.2"

Could it be that the people who vited it as the best java
library (in the "JDJ" awards) are using other parts of "JClass"
(and not the parts that we are using) ?

Thanks,
Avi.

I bought JClass a couple of years ago.  I really needed only one component
(the date/time picker) and that's all I use.  However, I spent a lot of time
writing workarounds and helper classes for just that one component and even
now two years later some of the problems still exist.  I wasn't overly
impressed with the quality and would not have spent the effort on it if
there were another component library available that had the component I
needed.

It will save time, but be prepared for some finicky behaviour.  One example
I can think of off the top of my head is the inconsistent return type
behaviour: if you select a date with the drop-down calendar, the value
returned is of one type, but if you key the date in manually the return
value is of a different type, and both types may be different from the type
you declared the field to be in the first place.  Very frustrating.

Our experience exactly. We also use the "date picker". We have
written *lots* of "workaround" code, but there are still bugs in
its behaviour. Similar problems with all of the other components
we are using (like "livetable").

For your information, we have found several similar date pickers
both freeware, shareware and commercial (but a *lot* cheaper
than "JClass") and are in the process of replacing the "JClass"
date picker.

Thanks for sharing your experiences.

Good Luck,
Avi.
