The goal of Project Phobos is to show that Java is an excellent platform for server-side scripting, allowing dynamic-language developers to leverage the power of Java SE and EE. The initial focus for Project Phobos is JavaScript, but the design supports the use of other dynamic languages as well....Project Phobos attempts to learn from Rails, but is not limited to the use of any particular programming language and may prove to have a different sweet spot
I checked... the word "enterprise" does appear on that page, but only in the breadcrumbs (" Projects > java-enterprise > enterprise-incubator > phobos).
