Using the Java 8 Date Time Classes with JPA! With the Java 8 SE release, developers get a splendid new best-in-class Date-Time API. Wouldn't it be nice if you could use it with JPA? Not so fast.

When I started my career as a Java developer close to 10 years ago, the industry is going through a revolutionary change. Spring framework, which was released in 2003, was quickly gaining ground and became a serious challenger to the bulky J2EE platform. Having gone through the transition time, I quickly found myself in favour of Spring framework instead of J2EE platform, even the earlier...
