Upgrading to Hsqldb 2rc8, part 1, Maven Integration

Wednesday, January 27, 2010

At my current client engagement, we make full use of hsqldb both in our unit tests and for local development. It’s a great tool, and the changes made since the last release 4 long years ago will make it an even better tool.
My project has hundreds of tests making use of hsqldb, and getting the [...]

Accessing Drools 5 rules via a restful API using Drools Server and Groovy RestClient

Wednesday, December 2, 2009

If you haven’t heard about drools, you should have a look at it now. It provides multiple ways to write rules: DSL (drl files), groovy, java, excel spreadsheets or via a web interface (Guvnor). I recommend the book, Drools – JBoss Rules 5.0 by Michael Bali as its the only comprehensive documentation available on drools.
One [...]

an interesting class loading issue with quartz scheduler timing (NoClassDefFoundError)

Thursday, October 29, 2009

My quartz job schedulers had a startDelay of 0 ms and a repeatInterval of 10 mins and 5 mins each. On my local environment (win/mac) and sandbox (unix) the scheduler works just fine. But in our production environment (unix), we were getting spurious java.lang.NoClassDefFoundError: Could not initialize class Foo. Now Foo was one of the [...]

Integrating JavaScript Tests with Continuous Integration

Monday, June 22, 2009

At my current client I’ve been building a rather complex rich client app using ExtJs. The team has written a lot of JavaScript code, and has been writing a lot of JavaScript unit tests as well.
We’ve gone through several unit testing tools along the way trying to solve some logistical problems. We started with JSUnit, [...]

The best 59$, a java developer can ever invest

Wednesday, June 17, 2009

If you don’t buy this now, you’re either dumb. Or just plainly stupid.
For the impatient: it’s a small jar that lets you compile/run/deploy java instantly, like php. I’ts the real HOT DEPLOY that jvm lacks out of the box.
No more restarting the server, ever again, even after reconfiguring Spring beans.
I used this for a month, [...]

Unit Testing JavaScript with HtmlUnit and Screw.Unit

Friday, May 29, 2009

Writing apps with today's rich client libraries such as Extjs , YUI , and JQuery really shows how much potential is still left in web development. But it takes a lot of code, and the amount of technical debt can get heavy, quickly. Good tests can help reduce this technical debt, and there are a lot of testing [...]

Mapping a clob type in hibernate and oracle 9i/10g

Wednesday, February 11, 2009

The easiest way to map a CLOB type of Oracle to a pojo in Hibernate, is to setup a user defined type in Hibernate, which converts Oracle’s ClobType to a String and vice versa. So you’re pojo’s property is going to be a “String” type. There are only two steps to setting this up:
1) Write [...]
