We deployed several sites on JRun without hitting any walls. Any issues encountered
turned out to be fixable application
programming, db locking or threading bugs in the application that were overcome with
app fixes. This was much to the clients'
surprise because they assumed that a $500 product like JRun wouldn't be able to
support their heavy loads (400 concurrent users).
Most of our clients have remained on JRun, but we have been migrating one large B2B
internet site from JRun to a
JSP/Servlet/EJB/WebLogic MVC architecture mainly for greater load balancing and EJB
support. We designed the original JSP/Servlets
to be portable so the conversion is going pretty smooth. FYI, JRun 3 now has app
server and EJB support. The client I am working
with prefers WL because of WL's maturity in the EJB world. In your case, how many
"concurrent" users are you trying to scale for?
If you need any help, fell free to contact me directly.

Subject: Offtopic: Architecture Question
We are building a B2B exchange for the semiconductor industry. Theres a
intranet version which is going to support 150 users, we are currently in
the process of building using JSP/Servlets and JavaBeans, we are using
DbConnectionBroker for connectionpooling services and JRUN as the
JSP/Servlet platform.
Question: The Client wants us to build an internet version of the system,
and obviously it has to be much more scalable(probably about 10,000 or more
users) than the intranet version. My Question is do we have to re-architect
the intranet system and go for an App Server like BEA Weblogic or IBM
WebSphere or does/can the Jrun architecture handle this load. This system
is not very transaction intensive and does not have the data concurrency
problems which most OLTP systems have.
Appreciate your inputs
Thanks for your time
Sanjay
