Spring, JPA/JTA, and multiple persistence units, with view transactions

I have grappled with this topic before. Tonight, after 13 hours of struggle, I finally got my web app perfected in this regard. It all started when I needed to start the Transaction out in the view, i.e. as soon as the resource is opened on the HTTP side (rather than when the database service […]

The UNIX time zone database has been shut down because of copyright complaints! Overthrow the DCMA!

Money-is-Money 0.17

I just released a new version of Money-Is-Money, v0.17. If you’re interested, see the features here and here. My aim with it is to make the most accurate currency-aware Java money handling library available. This time I’ve added just a couple of new methods to get the whole and fractional amounts as Integers (I use […]

Out of the box experience

Every now and again we get some customers who expect that they can get a custom website, portal, or services integration done by looking at a vendor’s “out of the box” experience.

Money-Is-Money v0.15 with added maven repository

In the course of an assignment for a client I’ve been giving Artifactory a good going-over. Artifactory is a Maven repository and mirror and is pretty cool and easy to set up – just drop the WAR file into a running Tomcat instance. On my Mac I ran it under Tomcat 6.0.18 with Java 5, […]

Money Is Money v 0.14

I’ve made a modest – very modest – library for dealing with Monetary amounts. IMHO something like this should be inside Java, to stop all those idiots using floating point logic to calculate money amounts. My library uses exactly NO EXTERNAL DEPENDENCIES apart from what’s already in Java 5 and Junit 3.8.1 for tests, which […]

Software sales jumped 21 percent year-over-year. What is fueling the growth? […]
