Build! Deploy! Maintain!

Build!
Easy startup - Jumpstart new projects with our bootstrap tutorial and template application or Maven archetype.
Improved Design - Code clean against HTTP-independant framework interfaces.
Enhanced Tags - Code less with stylesheet-driven form tags that provide their own markup.
Stateful Checkboxes - Avoid special handling with smart checkboxes that know when they are toggled.
Flexible Cancel Buttons - Go directly to a different action on cancel.
First-class AJAX support - Add interactivity and flexibility with AJAX tags that look and feel just like standard Struts tags.
Easy Spring integration - Inject dependencies into Actions using Spring without glue code or red tape. (Plexus support also available.)
Enhanced Results - Do more with speciality results for JasperReports, JFreeChart, Action chaining, and file downloading.
POJO forms - No more ActionForms! Use any JavaBean to capture form input or put properties directly on an Action class. Use both binary and String properties!
POJO Actions - Use any class as an Action class -- even the interface is optional!
Deploy!
Easy plugins - Add framework extensions by dropping in a JAR. No manual configuration required! Bundled plugins add support for JavaServer Faces, JasperReports, JFreeChart, Tiles, and more ...
Integrated profiling - Peek inside Struts2 to find where the cycles are going!
Precise Error Reporting - Flip directly to the location and line of an error.
Maintain!
Easy-to-test Actions - Test Struts2 Actions directly, without resorting to mock HTTP objects.
Intelligent Defaults - Skip obvious and redundant settings. Most framework configuration elements have a default value that we can set and forget. Say it once!
Easy-to-customize controller - Customize the request handling per action, if desired. Struts2 only does what you want it to do!
Integrating Debugging - Research problem reports with built-in debugging tools.
Easy-to-tweak tags - Customize tag markup by editing a FreeMarker template. No need to grok the taglib API! JSP, FreeMarker, and Velocity tags are fully supported.
