This simple demo contains an empty web application and a bundle jar with 2 actions that use FreeMarker, Velocity and Spring. To use it install the war file struts2-osgi-demo-1.0-SNAPSHOT.war in your server and navigate to: http://localhost/struts2-osgi-demo-1.0-SNAPSHOT/^{Image Removed}.

The Struts 2 OSGi plugin

...

1. Place your Spring xml files under /META-INF/spring in the bundle jar file
2. Copy all the bundle jar files into /WEB-INF/classes/bundles in your application
3. Make sure that the following properties are set in struts.xml or struts.properties in your application:

   Code Block
   XML XML
   <constant name="struts.objectFactory" value="osgi" /> <constant name="struts.objectFactory.delegate" value="springOsgi" /> <constant name="struts.freemarker.manager.classname" value="org.apache.struts2.osgi.BundleFreemarkerManager" />

4. Install the Struts 2 Spring plugin in your application, like in normal Struts 2 applications.
5. Configure your web.xml like:

   Code Block
   XML XML
   <listener> <?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Struts Blank</display-name> <filter> <filter-name>struts2-execute</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class> </filter> <filter> <filter-name>struts2-prepare</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2-prepare</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>struts2-execute</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.apache.struts2.dispatcher.ng.listener.StrutsListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextClass</param-name> <param-value>org.springframework.osgi.web.context.support.OsgiBundleXmlWebApplicationContext</param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>osgibundle:/META-INF/spring/*.xml</param-value> </context-param> </web-app> </listener> {code:xml} # Add the Spring OSGi dependency to your web app, if you are using maven: {code:xml} <dependency> <groupId>org.springframework.osgi</groupId> <artifactId>spring-osgi-web</artifactId> <version>1.1.2</version> </dependency>

6. Download Spring OSGi and copy all the required bundles under /classes/bundles/other. For Struts OSGi 1.1.2, these are the required bundles:
