These subprojects will all inherit version 1. Since many teams will use Struts with one or more extensions, we are bundling the jars for extensions that utilize the framework into a single distribution called "Struts Library".
The Apache Struts subprojects, including the website, are being built with Maven. But, of course, you can continue to build your own projects any way you like! The 1. A number of software dependency changes apply to this release: New dependency on Commons Chain 1. Upgraded to Commons FileUpload 1. New dependency on Commons IO 1. Upgraded to Commons Validator 1.
The applications have been moved into their own subproject, the builds have been "Mavenized", but the set of example applications is essentially unchanged.
In prior versions, the request processing guantlet is represented as a series of methods. While it was easy to override the methods to provide different functionality, it was not easy to use multiple extension that each wanted to override the request processor in a different way.
For Action 1. Rather than subclassing a monolithic object, we can now just replace Commands. Commands can also be inserted or removed, if needed, to extend or streamline the request processing gauntlet to meets the needs of different kinds of applications. We fully expect the Action 1. But, to be prudent, we wanted to release 1. We've made a few other changes and improvements in Action 1. If needed, the monolithic RequestProcessor from Struts 1.
However, we consider this RequestProcessor to be a legacy class. Once the new ComposableRequestProcessor is more-widely field tested, we expect that this class will be deprecated, moved to the Extras subproject, and ultimately removed. Arbitrary configuration properties let us externalize more of our configurations, encouraging reuse.
Arbitrary Configuration should make it easier for everyone to write reusable chunks of code, for ActionMappings, Exception Handlers, and other members. Here's why:. In Struts 1. Accordingly, in Struts 1. IntRange now checks select-one and radio fields. Example: This allows populating combo boxes with valid choices plus one additional choice with a caption something like "Choose one" and a value 0f "-1". Then when the user attempts to submit the form, you can look for the value of "-1" and advise if nothing was selected.
You can now force the clientside Javascript validation to check all constraints, instead of stopping at the first error. The "required" validation can now handle checkboxes, radio,select-one, and select-multiple field types. See the updated Validator example application to see these new features in action. A standard validateUrl rule lets you check if a property contains a well-formed URL. DigestingPlugIn - A new standard PlugIn that helps you create your own object graph in application scope.
This is handy way to create business objects for Actions to call. Check the latest MailReader eaxmple application to see the DigestingPlugin in action. What Changed? Build Changes struts.
