Subject Javalobby and dzone and devx.com do iBATIS...
Date Thu, 08 Jun 2006 03:16:09 GMT
This just arrived in my inbox...my regular JavaLobby newsletter.  I couldn't
find an online version, so I'm posting it here and will add it to the wiki.


After at least three months of on and off work, we are pleased to say that
dzone.com is finally ready for you to enjoy. (Be sure to read Matt's column
following this one for some detailed tips and insights about how to get the
most from dzone.com


That being said, we feel good about what we built to power dzone.com. To
begin with, we used Spring 2.0 and the Spring Web


But the more interesting technical choice was probably the selection of Apache
iBatis <http://ibatis.apache.org/> for data persistence. One of the great
advantages of Spring is that it makes it easy to support replaceable
implementations for your data persistence. Hibernate <http://hibernate.org/>,
of course, is a very popular choice and works well with Spring. We were
concerned, however, that with Hibernate we would be relying too heavily of
the ORM layer to perform database magic. Having learned from hard experience
that database optimization can have at least as much, if not more, impact on
overall performance of Java web applications, we thought it might be prudent
to stay a little closer to our SQL than Hibernate makes it easy to do. Now
don't get me wrong, we have used Hibernate with great success in other
applications, and Matt and I both respect and admire what this excellent
open source ORM layer gives you. We have also spen! t more than a few hours
watching database logs to find problems in Hibernate applications, and the
SQL Hibernate generates can be really scary. It's almost invariably correct,
but it has that machine-like bias for not caring whether the queries it
outputs are human-readable.

iBatis, on the other hand, allowed us to enjoy many of the advantages of an
ORM layer without handing over control to a black box, even one as competent
as Hibernate obviously is. We got to construct hand-written SQL for our
operations and correlate the results of those SQL statements with JavaBeans
that provide object-oriented mappings to and from the database backend.
Spring was equally well prepared to work with iBatis as it was with
Hibernate, so we had confidence that we could drop back to Hibernate if our
iBatis experiment didn't work out. It did work out, however. iBatis lets us
stay very close to the database, almost as if we were using direct JDBC
calls, yet we get to concentrate all of those calls behind a JavaBeans
abstraction that let us build DAOs, managers and work in a thoroughly
object-oriented data model without concern for the relational database
behind it. iBatis was a good choice for dzone.com, and I'm! glad we took the
chance to try it out. It's just one more case that proves there is more than
one way to get the job done well. Hibernate is extremely popular, but there
are other excellent options out there, too.

dzone.com looks great, and JavaLobby also has a new look and feel (since the
last time I was there anyway).  Check them out.

Also a link on dzone found me this:
