I was always under the impression that Jaguar was never meant to be a web
server. However, if I understand this correctly I need to use Jaguar's Web
Server to call servlets. We currently use IIS as our web server. Is there a
way that Jaguar can hook onto the another web server similar to the way
Dynamo hooks onto web servers?

If there is no plugin then what is the solution? In my case, running Jaguar
as a web server is definitely not an option.

Also, since we would be using a cluster of Jaguar Servers I would like to
use the same cluster to handle my servlet load. I believe Jaguar only load
balances IIOP requests. However, the servlet call would be HTTP. Will the
next release of Jaguar address these issues?

A few thoughts.

1) When we say EAS isnt a web server what we mean is we do not provide all
the services of a web server like CGI, etc. As for performance, we have
benchmarked EAS's HTTP speed and find it as good or faster than major web
server solutions

2) If you need servlet support for IIS you can get ISAPI servlet solutions.
JRun is popular.

3) We will not provide HTTP LB solutions. Mainly because there is nothing
inherint in HTTP to support LB. The best solution is a hardware solution
like CISCO. There are also cheaper sw based HTTP LB proxies. What we will
supply as far as HTTP LB and HA will be persistant HttpSession objects. So
you can have a cluster of EAS managing servlets and each server in the
cluster can share the same HttpSession information about clients. But if
you need to LB the HTTP traffic you still need hardware or DNS round robin
etc. This is the same for every application server I am aware of.

Hi

In which version and when will shared HttpSession be implemented in EAS?
Will EAS support JavaServerPages and container-managed Entity EJBs?

Thanks,

TineQ

1) HttpSession is supported now. A persistant HttpSession supporting HTTP
failover will be in the next release 3.6 in Q2

2) JSP will be in 3.6 in Q2

3) Container managed entity beans is there now, and will support O:R mapping
in 4.0 in Q4

Thank you for your reply.

A few more questions...

> JRun is popular.

Why isn't Sybase providing this? Why should anyone pay for JRun when Sybase
customers have already invested in Jaguar (which has servlet support). If
Dynamo
had servlet support then I would not need to look at any other products
(JRun).

Because our servlet engine is integral into EAS. We have no way to extract
it other than to build it from scratch. Were not a servlet provider. We
provide an application server that includes servlet support.
