Hi,
We are in the process of building a web site that will
support more than 10,000 concurrent users. I want to
use Java for any server side development. This
prompted me to look at JSP and EJB model. I am not
uptodate on J2EE stuff.

Does this mean that today JSP - EJB combination is not
supported by any vendor.
Also whether IIS supports JSP.

Where can I read about it ?
Whether EJB Servers will be able to keep a pool of
JDBC connections ?
Who will maintain the user session ? EJB or JSP. Can I
maintain user sessions inside a hash table in EJB ?
What is the cost of JSP making a call to bean and then
bean making a call to EJB server.
Based on the EJB tutorial, some context needs to be
established before a client can make a call to EJB ?
What is the cost of this context.
Thanks in advance

What will probably fit the bill for this is the
Reference
Implementation of the
Java2 Enterprise Edition (J2EE) -- anounced at JavaOne
-- which will
include
implementations of pretty much the entire suite of
functionality
(servlet, JSP,
EJB, and so on). Unfortunately, this won't be
available until later --
probably Q4 1999, but don't hold Sun to my guesswork!
In the mean time, you can concentrate on understanding
the basic
capabilities
of EJB servers, and then the implications of storing
references to your
session
beans and entity beans in your JSP sessions -- given
the ability of
both the
EJB platform and the servlet/JSP platform to be
implemented in a
scalable
fashion, and/or run on different servers, the future
looks pretty
interesting.
You can get a feel for what the entire scope of J2EE
will be by reading
the
white papers, and the J2EE spec, at:
