I actually like SQL. So, things like Hibernate with it's own query language don't quite fit my style. But, I don't want to code the same catch SQLException conn.close over and over either. So, I came up with this.
The idea is you extend SQLCommand (usually anonymously) override getSql(), and call execute() to get a list of whatever objects you are selecting - all the cleanup stuff is taken care of. It also handles nullable attributes more intuitively using ResultSetWrapper and PreparedStatementWrapper so that in your overridden getRow(ResultSetWrapper rs) method, you can call getInt on a nullable column and have it return null - what a concept! Also I like java.util.Date for my dates, so the wrappers convert to/from java.sql.Timestamp.
Right now I've only bothered with some basic types - it should be pretty clear how to add more if you need em.
See what ya'll think.
Oh, it uses JDK 1.5 Generics, but stripping that away would be pretty easy if you wanted 1.2 compliance.

A GroovyClassLoader demonstration. The given domain is a german water flow meter system; I think, you shouldn't be able to understand the domain, but you should be able to understand, how to load a Groovy class in Java via a GroovyClassLoader.

"form input" | "input focus" | autofocus | JavaScript 
0 comments
This script performs reliable, cross-browser input autofocus that often can be used simply by dropping it in, with no modifications to the form or HTML body. It refuses to switch focus if it detects that the user has interacted with the form (avoiding a major source of annoyance with autofocus scripts) and correctly handles Firefox tabs opened "in the background", which most autofocus scripts fail on. Official home is on the Lost Souls MUD Grimoire.
