THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Struts 2.0.0 is the first distribution of WebWork 2 as an Apache Struts product.
The current snapshot is graded "test build" quality. It is "ready enough" for early development – but there are gaps in the documentation, and early testing will undoubtedly expose other oversights.
For your convenience, a one-stop all distribution is available. Individaul elements of the distribution may also be downloaded separately.
The entire distribution, including all the elements. (36mb) |
|
The example applications, as ready-to-deploy WARs. (27mb) |
|
Just the blank application, ready to deploy as a template for new development. (Also included in apps.) (4mb) |
|
The documentation, as provided on the website (currently only the welcome page Javadocs, not the wiki pages). (6mb) |
|
The essential dependencies, including the Struts 2 JARs. (3mb) |
|
The source code for the framework, ready to build as a Maven project. (18mb) |
- If you are a Maven developer, you might want to get started using the Maven Archetype.
- Another quick-start entry point is the blank application. Rename and deploy the WAR as a starting point for your own development.

Key Changes
Depending on whether you are coming from a WebWork 2 or Struts 1 background, your perspective on the key changes will differ.
From WebWork2
- Struts 2 is dependant on XWork 2 (nightly build).
- Java 1.5 is required to build the Struts 2 distribution from source, but Java 1.4 is targeted for the binary JARs.
- Rich text editor tag has been removed (a possible replacement would be to use the textarea tag with theme="ajax", this will used dojo's rich text editor)
- Datepicker tag is now using dojo's (limited in terms functionality and internationalization)
- foo!bar functionality is off by default (could be truned on by having struts.compatibilityMode=true in struts.properties)
- prepare interceptor now uses reflection to call prepareXXX where XXX is the action method
- doXXX fallback method call is being removed.
- DispatcherUtil is being renamed to Dispatcher
- ConfigurationManager is no longer a static factory. It is now an instance created through Dispatcher
- Configuration is no longer statically accesible, it is created by ConfigurationManager.
- Custom configuration to ConfigurationManager and Configuration cannot be done statically anymore, instead use Dispatcher's DispatcherListener to achieve such effect.
