If for some reason the blank template or archetype doesn't work for you, here's how to setup an application from square one.

![]() | If you need to customize your own templates (how HTML is rendered from Struts UI tags), copy into your webapp directory the /src/java/template directory. |
The following files are a minium requirement for your application.
Filename | Description |
---|---|
struts2-core.jar | Framework library itself, found in distribution root directory |
xwork.jar | XWork library on which Struts 2 is built (version 2.0 or later) |
oscore.jar | OSCore, a general-utility library from OpenSymphony |
ognl.jar | Object Graph Navigation Language (OGNL), the expression language used throughout the framework |
commons-logging.jar | Commons logging, which the framework uses to support transparently logging to either Log4J or JDK 1.4+ |
freemarker.jar | All UI tag templates are written in Freemarker (also a good option for your own views) |
spring*.jar | The default dependency injection container for the framework. |
web.xml | Java web application configuration file that defines the filters (and other components) for your web application |
struts.xml | Framework configuration file that defines the actions, results, and interceptors for your application |
The library files (*.jar) needs to be copied to your /mywebapp/WEB-INF/lib/ directory. If you need optional functionalities requiring dependencies on optional JARs, those JARs need to be copied to this directory too.
Create an web.xml file in [webapp]/WEB-INF (or merge into it the framework resources).
<?xml version="1.0"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <display-name>My Application</display-name> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
The standard web.xml registers a FilterDispatcher to enable framework functionality for your requests. The ContextLoaderListener configures Spring as our dependency injection container. The framework uses Spring internally. (You may wish to use Spring to deploy your own objects too.)

Create a skeleton struts.xml file in /$APP/WEB-INF/classes.
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts><!-- Include framework defaults (from Struts 2 JAR). --> <include file="struts-default.xml" /> <!-- Configuration for the default package. --> <package name="default" extends="struts-default"> </package> </struts>
For now, the struts.xml does only two things:
