public class GuiceResolver
extends ManagedBeanResolver

Register this ELResolver in faces-config.xml.

<application> <el-resolver>org.apache.myfaces.el.unified.resolver.GuiceResolver</el-resolver> </application>

Implement and configure a ServletContextListener in web.xml .

<listener> com.your_company.GuiceServletContextListener</listener-class> </listener>

Configure Guice in your ServletContextListener implementation, and place the Injector in application scope.

public class GuiceServletContextListener implements ServletContextListener { public void contextInitialized(ServletContextEvent event) { ServletContext ctx = event.getServletContext(); //when on Java6, use ServiceLoader.load(com.google.inject.Module.class); Injector injector = Guice.createInjector(new YourModule()); ctx.setAttribute(GuiceResolver.KEY, injector); } public void contextDestroyed(ServletContextEvent event) { ServletContext ctx = event.getServletContext(); ctx.removeAttribute(GuiceResolver.KEY); } }
