"Yet Another Multicolumn Layout" (kurz: YAML) ist ein (X)HTML/CSS Framework zur Erstellung moderner, flexibler Layouts auf Grundlage von float-Umgebungen. Dabei stehen ein Höchstmaß an Flexibilität für den Webdesigner und Zugänglichkeit für die Nutzer im Vordergrund.
Representational state transfer (REST) was introduced in early 2000 by Roy Fielding's doctoral dissertation. However, in the Java community, it was not standardized until JSR 311(JAX-RS) was finalized in 2008. The first release of its reference implementation is even later. In this article, I introduce Jersey, which is the reference implementation of JSR 311, by describing its essential APIs and annotations. I'll also show you how you can smoothly transfer from servlet-style services to RESTful services by integrating Jersey into Apache Tomcat.
