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.

A simple, yet powerful (what a cliché) way of resgistering javascript keyboard shortcuts. Register any kind of keyboard shortcuts, and if applicable, override the browser default action.

From time to time you may have reasons to override the default find method that ActiveRecord provides. In this example, we'll store a side-copy of the record attributes so that we have some basis for discovering changes to the data.
note: this will not override dynamic finders such as find_by_id

A quick implementation of an encrypter which can't be cracked by frequency analysis.

The decrypter for the simple encrypter I posted earlier - Takes the encrypted text from a text file - "encrypt.txt" which the encrypter automatically writes to.
