[CONF] Apache Wicket: Resin-IoC integration (page created)

[confluence]

Page Created : WICKET : Resin-IoC integration Resin-IoC integration has been created by Scott Ferguson (Mar 24, 2008). Content: Resin 3.1.5 includes Wicket plugins to support full WebBeans (JSR-299) integration for the Wicket application object, and dependency injection for component objects. The Application object can use the following capabilities: Injection using @In, @Named, and custom @BindingType injection for both application services and components and app-server resources (databases, jms, ejb, etc) Predefined aspects such as EJB's @TransactionAttribute and @RolesAllowed Both WebBeans and EJB interception using @Interceptors or @InterceptionType WebBeans @Observes for listening for application events The components get @In and @Named injection, but not the other capabilities, since interception conflicts with the Wicket style of allowing components to use "new" for easy instantiation. The three plugin classes are com.caucho.wicket.ResinApplicationFactory - for creating applications com.caucho.wicket.ResinComponentInjector - for injecting component resources com.caucho.wicket.ResinWebApplication - as a convenience for injecting resources The application factory is configured in Wicket's <filter> definition as the applicationFactoryClassName. The sample WEB-INF/resin-web.xml might look like the following: <pre><code> <web-app xmlns="http://caucho.com/ns/resin"> <filter filter-name="wicket" filter-class="org.apache.wicket.protocol.http.WicketFilter"> <init-param applicationClassName="demo.HelloWorldApplication" applicationFactoryClassName="com.caucho.wicket.ResinApplicationFactory"/> </filter> <filter-mapping url-pattern="/*" filter-name="wicket"/> </web-app> </code></pre> The component injector is registered with your Application object and looks like the following: <pre><code> import com.caucho.wicket.*; public MyApplication extends WebApplication { public MyApplication() Unknown macro: { addComponentInstantiationListener(new ResinComponentInjector()); } ... } </code></pre> The Resin wiki page at http://wiki.caucho.com/Wicket also provides an up-to-date documentation of the integration.
