Introduction
Struts 2 Plugin for JetBrains IntelliJ IDEA provides tight and feature-rich integration to develop Struts 2 applications. Real productivity features (including refactoring support) and understanding the structure and framework will make you more productive instantly. No more countless wizards just generating some XML or code without much intelligence!

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.
Fileset 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
Many features will NOT work if this setup has not been performed properly
Dedicated facet with configuration options
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.
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.
Library validator/setup
Creates IDEA project/module-library and - if required - downloads all necessary JAR files required for Struts 2.
Library validator/setup for standard plugins (Spring, Tiles, JSF, ..)
Autodetection of Struts 2 facets
Existing struts.xml-files are recognized upon opening your project and a new S2 facet will be created automatically.
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
"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):
"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.
Dedicated dictionary
IDEA 11+
A bundled dictionary providing Struts-specific words and acronyms integrates with IDEA's builtin spellchecker.
Dedicated icons Struts elements
Recognize Struts related configuration files or code at a glance throughout the IDE (Project/Packages View, Editor tabs, Autocompletion, …):
struts.xml/validation.xml
Autocompletion
Please see this screencast to see it "in action" (a small part only!).
Autocompletion (CTRL+Space) is available for virtually all tags and attributes, just give it a try:
Rename refactoring/Find Usages
Need to refactor your S2 application? No more manual search and replace - just use Rename refactoring (Shift+F6) or perform Find Usages (Alt+F7/Ctrl+Alt+F7):
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).
Highlighting of configuration/reference errors
Errors are highlighted immediately in the editor, additional validation is triggered for Make Project.
IDEA 7: see "Validation" tab in S2 facet for more options
IDEA 8+: see Settings->Compiler->Validation
Quickfixes
Various quickfixes to create missing elements etc.
struts.xml: restrict resolving to <result> value depending on result-type (e.g. Tiles, Velocity)
IDEA 10+
Completion will only show resources relevant for the given (or inherited) result type.
Configuration errors
Highlight common configuration errors or possible problems on-the-fly - while you're editing. Catch the bugs before time-consuming deploy & manual-test.
Structure View
Visually groups all relevant info with Autoscroll from/to source. Hint: searching for something in the tree? Just start typing its name to find it.
struts.xml: Pageflow graph
IDEA 8+
Graph of all actions and results makes it easy to understand the structure of your application.
validation.xml
Navigation to/from corresponding Action-class
IDEA 11+
Autocompletion/Navigation to Action-class properties in <field> "name"
"Navigate -> Related File" from Action-class to corresponding validation.xml file(s).
Show validation.xml node(s) under corresponding Action-class (like GUI-Designer forms)
Create corresponding validation.xml-template from Action
IDEA 11+
Intention to create new ActionClassName-validation.xml from file template.
Structure View
I18N-support
IDEA 11+
Support for .properties-based I18N for <message> "key" (can be disabled in S2 facet, tab "Features").
Actions (JAVA/Groovy)
Navigation to Action-declaration in struts.xml
Simply click on the action icon in the left editor bar to quickly open up the corresponding mapping(s) in struts.xml:
IDEA 8.1.1+: Groovy support added
Navigate to result
IDEA 10.5+
Use the gutter icon (or use Navigate->Related File) to directly navigate to any result(s) from your action method:
JSP
Navigation to Action-declaration/class
Click on the Action-class icon to quickly open the corresponding Action-class or Ctrl+click on the "action"-attribute open its struts.xml-definition:
Autocompletion/navigation for form properties
IDEA 11+
Form properties will be autocompleted/resolved in "surrounding" Action class. Ofcourse, rename refactoring and finding usages is supported here as well - no more manual search and replace necessary when updating your forms!
Autocompletion/navigation for other tags
Autocompletion is available for (almost) all attributes with static values.

OGNL (Object Graph Navigation Library) Support
IDEA 11+
Provides editing, highlighting and autocompletion support for OGNL expressions - not just for Struts 2 applications.
Please see Struts 2 Plugin OGNL Support for details.
Plugins/3rd Party Extensions
Spring plugin
(plugin "Spring Support" must be enabled and Spring facet setup properly)
Please see this screencast to see Spring integration "in action".
Reference Spring beans where supported (e.g. in <action> "class", <constant> "value").

Sophisticated configuration properties support
Autocompletion/navigation/usage search in annotations (WIP):
Tiles 2 plugin
