Links of the Week (CW41) - Wildfly

Hello and welcome to "Links of the week (CW41)" :-)

This week was really busy for me, so there was not so much time to read interesting articles. But that does not mean, that nothing happened. Wildfly 8.0.0.Beta1 was released on the 4th and it became my main topic of the last days. It is the first Wildfly release which implements all user facing EE7 APIs and contains several other improvements like the new high performance web server Undertow. Check the Release Notes and Documentation for more information.

Bear Giles wrote a great article about Database Encryption Using JPA Listeners. He describes a nice and easy way to separate persistence and security by using JPA Listeners.
JPA 2.1 Type Converter are an alternative way to encrypt data before persisting it in the database. A Type Converter can be used to convert an attribute from its entity representation to its database representation and back. If you want to learn more about Type Converters, have a look at the article I wrote on Monday: JPA 2.1 - How to implement a Type Converter

Have fun!
