Play 2 vs ActFramework

With some basic starting tutorials and a fleshed out documentation, there will be no need to go asking others for help, there should be enough for a developer to find a solution.

Everything with Play has been built with asynchronous requests in mind. This will result in the application not blocking results while waiting on other operations. With this implemented your application can be developed with multiple threads in mind without worrying about hanging on one request before it completes another.

All error checking and testing done in the browser only needs a page refresh to show the latest updates. This is huge, allowing the ability to code in real-time and make quick edits. Without it the develop would need to reboot/recompile the entire application to test with new data.

There are two aspects of performance: how quick a developer can deliver a feature and how fast the app is running on the product server. Act is designed to deliver excellent results in both aspects. With unbeatable developing experience, Act makes it very easy to release a feature; on the other side Act is very fast in runtime. Check out this 3rd party benchmark result.

You never restart while you're working on your Act application. Act's hot reload feature is fast and stable, it makes you feel like dealing with scripting language frameworks like Django or NodeJs. Watch this video and feel it.

Act is built as a stateless framework. It supports horizontal scale.

Act is built as a secure product. It provides built-in CSRF/XSS prevention mechanism. And act-aaa makes it very easy to implement Authentication/Authorization/Auditing in your app.

Act makes creating RESTful service a kids game. It features AdaptiveRecord (allows front end to drive the data structure), JSON response control (just declare the fields you want to present or hide) and RESTful URL routing with path variables.

ActFramework is not a servlet framework and there are no requirements on containers/app servers. It has a small package size (a helloworld distribution package size is less than 20 MB), a small memory feet print (a helloworld app heap usage is less than 20MB) and a fast boot up speed (a helloworld app starts in less than 3s).

Act's view architecture is very flexible and support using multiple view engines in your app. The default template engine is Rythm, a very developer friendly and powerful template engine. Act also support other templating solutions including freemarker, velocity, thymeleaf, and mustache via plugins.

Act supports load configuration from a common dir and then overwriting it from a profile dir. Makes it very easy to manage configurations in different environments (e.g., dev, uat, sit, prod) Watch this video to see the innovative way Act delivers its configuration support.

Act does not require you to put Annotation when it is able to infer the intention from other parts of the code, i.e., you don't use @PathVariable or @RequestParam to tell Act the binding parameter name. And you don't need a ModelMap to bind variables to render argument names. Act has sophisticated byte class scanner to detect the variable names to do bindings automatically.

Act's IoC is built on top of Genie, a fast dependency injection library that fully supports JSR330, and Act's validation solution is built on top of JSR303. Act is NOT an odd framework to most Java developers. Unlike Play1.x, ACT applications follow the standard maven project structure and it is very easy to integrate other Java libraries.

Act's DB layer is extremely easy to use. It supports SQL databases (through ebean orm) and MongoDB (through morphia). Using multiple datasource can never be that easy with Act's DB layer. Go here for more information on this.

You can configure your routing in either Spring MVC/Jersey style with annotation or Play style with route table or a combination of both. Act's routing supports RESTful URL path variables, optionally validated with regular expressions.
