Re: Enterprise Java

Hi Mike,

I think there are opportunities for miscommunication here. "Web
service" means something specific to most Java developers and that's
something substantially different from just accessing multiple databases.

Secondly, your answer really doesn't tell us anything about the
"enterprise" needs of your application(s.) So we can't really say if just a
web container like Tomcat or Jetty is sufficient or if you need something
that supplies more services. There are a lot of options around.

"persistent data connections" doesn't sound like a very good idea at
first, but that's essentially what connection pools provide, and you should
probably look to using those regardless of whether you use a web or
J(2)EE container. There are also a number of other factors that contribute
to database related performance beyond just connection persistence.

The lead web developer wants to use persistent data connections to
databases. This web service would grab data from MS SQL, the System i, and
untold # of other databases for use on the main City website. So speed is
the key here.

Mike,

It depends what you mean by "Enterprise Java web service". WAS Express
(included with i5/OS) and WAS CE (Community Edition), a free
implementation of the Geronimo project, would be IBM supported
alternatives as well. JBOSS would work as well. Tomcat could also fill
the bill. A bit more about about your application might be helpful.

wondering if using JBoss would work?
