I am getting a 404 with the link right now. Railo is a JBOSS project that is an open source version of CFML. Here's what they say about Railo in comparison to PHP:
• Simplicity
More powerful tags for simple file, email, database and other common operations.
• Best Practices Support
If you want to build OO apps using TDD, you can do so. If not, you can still hack out working scripts in minutes.
• Frameworks
A wide range of frameworks designed to make it quick and easy to build well designed web applications.
• OSS Projects
RIAForge has hundred of pre-built projects so you can quickly deliver anything from a blog to a content management system.
• Robust deployment
Railo CFML is easy to manage and deploy, but it's sitting on top of the Java Virtual Machine so it can be deployed to any servlet container or J2EE application server and can take advantage of all of the tooling available for deploying and maintaining Java applications (JMeter, Maven, etc.).
Is this more clear?
