- It's small, very small, in fact it's tiny! It's only 31kb total! That's right, I said kb. Most web pages are larger than that, let alone an entire server side web application framework!
- It's packed with features. You can literally build entire web applications with it and not need to code any custom features. gcaddy.com is proof.
- It's completely configurable (or rather declarative) via XML. It's based on the idea that applications should be configured, not written. Most of the code you need to write is included in the framework, so why write more.
- It's easy, you don't need to be a Java expert to use it. In fact, your better off knowing XML, Javascript and SQL, because most (if not all) the Java is done for you.
- It deploys as a J2EE compliant web application, therefore reaping the benefits and robustness of an enterprise grade platform.
