Uhh-ohh, I hear the rumble of a deluge of emails on this topic hitting the list - but
I cant help posting my 2 cents.
EJB is for small sites also. IMHO it does add an improvement over simply using PHP.
I'm pretty sure you cant isolate business logic in such a way as to be available to
other languages/applications using PHP. With EJB you can. I think components take OO
to the next level - that alone is enough to justfy using it IMHO.
Websphere et. all. are kind of expensive monsters for a web application, but, JBoss
and Jonas, type projects are changing all that!
I'm biased, I've been hooked on COM for a long time prior to Java - EJB just seems a
natural design decision - unless your doing a high-volume site - then do minimum
code/calls neccessary to get the job done.
Besides, PHP/ASP consultants make about $30-50 bucks per hour while EJB consultants
make $50-120 ;-)
After a few initial hurdles, I have found JBoss as easy to work with as Visual Basic
COM - other then VB's debugger -but I'm learning Junit & Java debugging.
The same cant be said for my experiences with Websphere 3.02 - yuch!
Just my 2 cents.

Gosh! Lay off the guy. You have no idea why he's decided to re-write his
site, so why is everyone coming down on him like he's some kind of a moron ?

Subject: Re: [jBoss-User] J2EE Too Much for Small App? Rocky Honeymoon!
Hi Hunter,
I think you need to read this article, by Brett Mclaughlin, "Enterprise
Applications in Java and J2EE: A Rocky Honeymoon."
visit: http://java.oreilly.com/news/j2ee_0700.html
An excerpt:
All too often, people
go overboard with their applications. In geek talk, this is
called "buzzmania." Buzzmania is the tendency to buy
more, get more, and use more, simply because more
"buzzwords" are in a product. This is a large part of the
J2EE problem. With the J2EE product descriptions and
specifications reading like a meeting of exotic 12-step
programs--JSP, XML, JMS, EJB, CMP, BMP, OR, JDBC--it's
no wonder managers' eyes light up at sales presentations.
However, the reality is few companies, and few
industries, need all these services. I'd estimate 50% to
70% of the companies that have purchased or are
purchasing J2EE solutions could easily get by with a
simple servlet and a JDBC-based solution. Presentation
logic housed in the servlet coupled with database access
through JDBC would suffice for most types of
applications, including many e-commerce solutions.
Adding JSP, or another presentation technology, such as
Enhydra XMLC, makes this an even more robust option.
Regards
Fred
