Description

Since servlet 3.0 web applications can be set up completely in code.

To support this kind of setup wicket should

• support the manual assignment of an web application instance to WicketFilter
• support setting the runtime configuration type in WebApplication programmtically through a setter instead of reading web.xml

sample code for demonstrating the use case:

public class AppContextListener implements ServletContextListener
{
private GuiceContext guiceContext;

@Override
public void contextInitialized(ServletContextEvent sce)

{ // create configuration final AppConfig configuration = new WebAppConfig(); // setup guice guiceContext = new GuiceContext(configuration); // create injector final Injector injector = guiceContext.createInjector(); // create wicket application WebApplication application = injector.getInstance(WebApplication.class); application.setConfigurationType(RuntimeConfigurationType.DEVELOPMENT); // create wicket filter WicketFilter filter = new WicketFilter(application); filter.setFilterPath(""); // dynamically add wicket filter final FilterRegistration.Dynamic wicket = sce.getServletContext().addFilter("wicket", filter); // add filter mapping for path '/' wicket.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), true, "/*"); }

// ...
}
