Key Changes

Depending on whether you are coming from a Struts 1 or a WebWork 2 or Struts 1 background, your perspective on the key changes will differ.

From Struts 1

• See Comparing Struts 1 and 2
• More notes to come ...

From WebWork 2

• Struts 2 is dependant on XWork 2 (nightly build).
• Java 1.5 is required to build and deploy Struts 2.
  • For Java 1.4 deployments, RetroWeaver or RetroTranslater may be used to provide Java 1.4 support
  • A pre-packaged set of RetroTranslator JARs are being provided with the distribution.

For other changes from WebWork 2, see the "Members to rename", "New property settings", "New members featrues or feature changes", and "Removed or deprecated".

features and feature changes

• Datepicker tag is now using dojo's (limited in terms functionality and internationalization)
• Various changes to ConfigurationManager
  • ConfigurationManager is no longer a static factory. It is now an instance created through Dispatcher. Custom configuration could be done through DispatcherListener.
  • Custom configuration to ConfigurationManager and Configuration cannot be done statically anymore, instead use Dispatcher's DispatcherListener to achieve the same effect.
• The prepare interceptor now uses reflection to call prepare_Method_ where method is the action method configured for the particular action in struts.xml.

  Code Block
  <action name="myAction" method="insert" ....> ..... </action> // with the above configuration, and PrepareInterceptor in play, // callsequence will be 1] prepareInsert() (If it exists) 2] prepare() (Unless Interceptor's alwaysInvokePrepare parameter is set to false) 3] insert()

• DefaultWorkflowInterceptor (named workflow in struts-default.xml) now uses reflection to call validateMethod on the action class that implements Validateable interface where method is the action method configured for the particular action in struts.xml.

  Code Block
  <action name="myAction" method="insert" ...> ... </action> // with the above configuration, and DefaultWorkflowInterceptor in play, // call sequence for action that implements Validateable interface will be 1] validateInsert() 2] validate() (unless Interceptor's alwaysInvokeValidate parameter is set to false) 3] insert()

• Datepicker tag is now using dojo's (limited in terms functionality and internationalization)
• Tiles integration extension is available.
• Wildcards can be specified in action mappings.
