Samples
The Play 2.0 package comes with a comprehensive set of sample applications written in both Java and Scala. This is a very good place to look for code snippets and examples.
The sample applications are available in the
samples/directory of your Play installation.
This is a very basic application that demonstrates Play 2.0 fundamentals:
- Writing controllers and actions.
- Routing and reverse routing.
- Linking to public assets.
- Using the template engine.
- Handling forms with validation.
This is a classic CRUD application, backed by a JDBC database. It demonstrates:
- Accessing a JDBC database, using Ebean in Java and Anorm in Scala.
- Achieving, table pagination and CRUD forms.
- Integrating with a CSS framework (Twitter Bootstrap).
Twitter Bootstrap requires a different form layout to the default one that the Play 2.0 form helper generates, so this application also provides an example of integrating a custom form input constructor.
This is a dummy application presenting several typical form usages. It demonstrates:
- Writing complex forms with validation.
- Handling forms with dynamically repeated values.
This advanced todo list demonstrates a modern AJAX-based web application. This is a work in progress, and we plan to add several features in the future releases. For now you can check it out to learn how to:
- Integrate authentication, and security.
- Use AJAX and the Javascript reverse routing.
- Integrate with compiled assets - LESS CSS and CoffeeScript.
This a very simple Comet demonstration pushing clock events from the server to the Web browser using a the forever-frame technique. It demonstrates:
- Create a Comet connection.
- Use Akka actors (in the Java version).
- Write custom Enumerators (in the Scala version).
A Chat room built using WebSockets. Additionally there is a bot used speaking on the same chat room. It demonstrates:
- WebSocket connections.
- Advanced usage of Akka.
