Velocity: A template engine OR A Rule engine OR Both?

TheServerSide.com - Velocity: A template engine OR A Rule engine OR Both?: "I have already used Velocity to generate my GUI. However, this time, I was looking at it with a different point of view. I was compiling its features in terms of a rule engine and it seemed to me a considerable fit for this new framework. Then it became a perfect fit when I realized its uses of toolbox concept as well. The toolbox concept provides the power to rule an author to access any EIS or application (almost anything) at runtime and with a complete transparency to the author."
