There are at least three commercial implementations of JSP. JRun,
ServletExec, and WebSphere. All three of them provide excellent support if
there is a problem and rarely (not "usually") use the excuse that "it has
not been finalized
yet!" All three provide support for the 0.91 spec, and some (such
as JRun) are providing 0.92 support as well. The implementations are robust
and very usable. The JSP is portable between the platforms (as long as you
stick to the 0.91 spec) The tech support from all three platforms is
decent. It's not always great, but it's there.
To say there isn't currently a finalized spec is a bit incorrect.
The 0.91 is "final" for 0.91. The 0.92 spec is "final" for 0.92. There
won't be any more changes to those specs, only new releases of the specs.
If you believe that JSP is not useable because it's version doesn't have a
"1" in front of it, then you are missing out on one of the best new
technologies to hit the Web scene in quite a while.
I agree that Sun's JSP team could be more communicative with this
list than they are right now. I'm a member of the Servlet list serv and the
Sun JSDK team is very responsive. My own personal opinion is that the 1.0
spec is probably very close to being done. It may even be done already. I
suspect that Sun is withholding it pending a release of their reference
implementation, which probably isn't done yet.
I also suspect something a bit more mercenary on Sun's part. I
suspect that they are putting JSP 1.0 support in their JavaServer or Java
Web Server product and want to be the first to market with a 1.0 JSP engine.
That way the other servlet engines will have to play catch up with Sun. If
I was a producer of third-party servlet engines, I'd be suspicious...
