Combining reflection, dynamic proxies, and annotations proves to be such a powerful technique that it deserves its own name.

eflection, dynamic proxies, and annotations are far from new capabilities in Java, having been introduced in JDK 1.1, 1.3, and 1.5, respectively. Lately, though, I've witnessed a spectacular combination of these features in a number of different projects. The combination is quite innovative, so much so that I was surprised no one had coined a name for it. So, I decided to call it the Proxied Interfaces Configured with Annotations (PICA) technique, which this article describes.
