We're currently using Apache, Tomcat, MS SQL Server, and Jonas EJB server.
Everything is working fine so far. We are not yet production but our
application has been used by several users at once and runs for days before
being shut down for upgrade. In production we will need to support 1-2
hundred concurrent users (users, not requests). I expect us to achieve that
with our current setup.
Our HTML interface is mostly JSP. A single main servlet delegates incoming
HTTP requests to an appropriate "toolkit". The toolkit makes calls to EJB
beans, creates beans for its associated JSP page, and then invokes the JSP.
Toolkits only talk to session beans (no entity beans are made available to
clients, only session beans). Our session beans use entity beans for data
access. Our entity beans employ bean-managed persistence.
We use Tomcat as a drop-in replacement for the JServ servlet engine. Tomcat
talks AJP v1.2 to mod_jserv.
This setup actually works with either JDK 1.1.7B or JDK 1.2.2. Should run
on either Linux or Windows (but I think the JDBC driver we're using only
works with JDK 1.1.7B on Linux).
We've been very productive with this arrangement. However, we've had a lot
of prior experience with the tools we're using. We've already climbed a
rather steep learning curve. IMHO open source software is harder to use
than commercial software.
food for thought. I'd be interested to hear others impressions of this
arrangement.
