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.

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.
