Velocity: Fast Track to Templating
Velocity is a fast and easy-to-use Java-based templating engine. Velocity's speed, ease of use, and flexibility contribute to its use in a broad range of applications, including code generation, email templating, and web user-interface creation. This article first introduces Velocity with a simple, easy-to-run example, then briefly covers the templating syntax, and ends with a full-featured and detailed look at Velocity in action for templating automated emails. Dec. 16, 2003

The Network is the People: Is JavaOne about the technical content? For most developers, yes. Is it about marketing products? For the vendors, sure. Is it about getting industry hype and announcing new stuff? For Sun, sure. But to me, it's about getting together with friends, and *networking* at a far more meaningful level than any technical session, keynote, vendor sales pitch, or new Java release.
