Setting Up a Struts 2 Project

Required JARs

A Struts 2 web app needs the core jars: struts2-core, xwork-core, ognl, freemarker, commons-fileupload, commons-io and commons-logging.

Web Project Steps

1. Create a Dynamic Web Project in Eclipse.
2. Add the Struts 2 jars to WEB-INF/lib.
3. Configure web.xml with the Struts 2 filter.
4. Create struts.xml in the classes/src folder.
5. Write an Action class and JSP views.

web.xml Filter Mapping

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Key Points

• Deploy the WAR to Tomcat and hit action URLs.
• struts.xml maps actions to classes and results.
• All jars belong under WEB-INF/lib.
