Starting with IntelliJ IDEA 12.1 icons have changed slightly.

Struts 2 facet

All plugin configuration settings are bundled in a dedicated facet. Simply attach a new Struts 2-facet to an existing Web-facet, create a fileset and add your struts.xml-files from all auto-scanned configuration files in your project and the plugin is ready to work.

Note
titleFileset configuration

struts-default.xml from struts2-core.jar as well as any struts-plugin.xml from plugins (e.g. Spring integration) have to be added additionally to the fileset.
Also make sure to add all files used via <include>.
10.0.2+: projects created using project wizard will include all struts.xml-files from Struts-JARs automatically
(warning) Many features will NOT work if this setup has not been performed properly (warning)

(tick) Dedicated facet with configuration options
(tick) File Set manager

Group and manage your struts.xml-files with an easy to use editor, providing maximum flexibility w/r to your project setup.

(tick) Detect struts.xml files not mapped to file sets

Spot setup errors easily, additionally providing a quickfix to add the unmapped struts.xml-files to any existing fileset.

(tick) Library validator/setup

Creates IDEA project/module-library and - if required - downloads all necessary JAR files required for Struts 2.

(minus) Library validator/setup for standard plugins (Spring, Tiles, JSF, ..)
(tick) Autodetection of Struts 2 facets

Existing struts.xml-files are recognized upon opening your project and a new S2 facet will be created automatically.

(tick) Integration with "New Project"

Add a blank ready-to-start Struts 2 application template by selecting Struts 2 from the list of available technologies. A S2-facet with default fileset and an empty struts.xml-file already mapped in web.xml will be created automatically, all necessary libraries will be setup as well.

IDE integration

(tick) "Go To Action/Package" by name

Press Ctrl+Shift+Alt+N (Go To -> Symbol) to quickly navigate to any Action/Package by simply entering its name (including wildcards):

(tick) "Navigate -> Related File"

Tip: just start typing to narrow down the result list of related items and press ENTER to navigate.

IDEA 10.5+
Use this shortcut to quickly navigate from any web-resource used in <result> to its <action>-declaration and/or Action-method.
IDEA 11+
Also vice versa from Action-class to <action>-declaration and any referenced result(s) files.
Navigate from Action-class to all corresponding validation.xml files.

(tick) Dedicated dictionary

(tick) Navigation to referenced elements

Simply Ctrl-click (or press Ctrl+B) on any element to navigate to its declaration - or take a peek without leaving the current editor using Quick Definition Lookup (Ctrl+Shift+I).
