JSP just makes web pages in HTML.  ActiveX can be embedded in HTML. So
naturally JSP can make pages that include an ActiveX

I suggest asking in comp.infosystems.www.authoring.html for advice on
HTML syntax to include an ActiveX  (you'll get better advice than in
the M$oft groups).

Generating this HTML from JSP is easy, just look at the output to debug
it and make sure it generates what you expect. Feed the resultant code
to a HTML validator too.

I'd advise (it's not essential, but it's good practice) to use a tag
library, rather than raw in-line JSP, to embed the <object> tags you
use for your ActiveX. Tag libraries are always a good idea, but
especially so for a complex tag like this.

Whenever you use ActiveX, be aware that they're far from portable on
today's web. There are browser compatbility issues, but more
significantly, most sensible users just don't permit new ones to be
downloaded and run. They're too much of a security risk.
