Resin is very fast indeed. Resin has some nice features too, that recently
Orion incorporated as well. Orion in my opinion offers the best bang for the
buck. First..its free for all use except commercial use. Its a full J2EE
implementation app server, where as Tomcat and Resin are Servlet 2.2/JSP 1.1
containers only..no EJB support, etc. Tomcat doesn't have any fail-over
ability as far as I know, but the latest version may support that now. In
tests, I was told Orion is the fastest overall, slightly edging Resin in
static and dynamic page returns (JSP pages).
WebSphere is a crappy product from what I have heard thus far. Its very time
consuming to install, and it isn't up to date by a long shot. Even though
IBM just announced $2,000,000,000 of support, their latest offering (3.5)
still only supports JSP 1.0 and Servlet 2.1. That is pretty sad in my
opinion..seeing as how they are so devoted to Java and all.
WebLogic is a good one, but it is very expensive (as is WebSphere). We are
actually going to be using WebLogic (to my dismay..I wanted Orion) for our
site. It does have a strong presence on the app server market, with
excellent support and help. Their documenation on their site is extensive
with details on everything EXCEPT web app deployment ("root" web app
anyways). I am having a problem getting my web app running with WebLogic,
which is a breeze to do in Orion.
For whats its worth..if you are allowed, go with Orion. It offers the best
performance I have seen, it allows "auto" source reloading to keep the
server up while developing, fail over, session fail over, load balancing,
ejb, jndi, javamail, jsp, servlets, connection pooling, transaction
management (I think), and a slew of other features. For $1500 per server,
its 10% of the price for WebLogic for a single cpu. If you have a quad
server, WebLogic will cost you $60,000. Orion costs you just $1500. Thats a
HUGE difference in price. Especially when you start dealing with multiple
servers each with 2 cpus, etc. WebLogic can easily cost in the low to mid
$100K range, not including tools to develop for it, which run another $5K
per seat. Orion doesn't have any tools for development, but the nice thing
is you can use your favorite tool to do it all. I use KAWA myself, but Forte
is a decent one too. The next version of Forte will be much better than the
current release.
Hope that helps.
