The Missing Link

Attaching a GUI to a domain model object (a.k.a. "Entity") is a boring job. You need to write lots of synchronization code or models to change the UI when the entity changes and vice versa. Now that has an end. Here is the ultimate, automatic glue generator: The Java Beans Binding API. It allows you to glue together two Java Beans (i. e. POJOs, and has nothing to do with Swing or EJB). Just tell the API that you want to glue property X of beans A to property Y of bean B and "magically" from now on they will have always the same value. It even will internally translate data types! Cool stuff. What can we do with it? For example, you could tell the API that you want to glue your GUI directly to a EJB 3 Entity. How easier could it be to code a data view? Here is a small sample. Actually it is not using EJB 3, but hey, as you know, turning that class Person in a EJB 3 entity is as easy as adding @Entity to it's definition... ;-) public final class Person { private String firstName; private final String lastName; public Person(final String firstName, final String lastName) { this.firstName = firstName; this.lastName = lastName; } public final String getFirstName() { return this.firstName; } public final String getLastName() { return this.lastName; } public final void setFirstName(final String firstName) { this.firstNa...
