Class OsgiWebApplicationFactory

  • All Implemented Interfaces:
    IWebApplicationFactory
    public class OsgiWebApplicationFactory
extends Object
implements IWebApplicationFactory
    An IWebApplicationFactory which looks up a WebApplication from the OSGi service registry.

    In an OSGi context, classes from client bundles cannot be loaded by name in general. This factory loads a WebApplication service from the OSGi service registry, using a property with key APPLICATION_NAME_KEY for disambiguation.

    To bootstrap your Wicket Application when running under OSGi, configure the WicketFilter in your web.xml deployment descriptor as follows: 

       <filter>
     <filter-name>Wicket</filter-name>
     <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
     <init-param>
       <param-name>applicationFactoryClassName</param-name>
       <param-value>org.wicketstuff.osgi.OsgiWebApplicationFactory</param-value>
     </init-param>
     <init-param>
       <param-name>wicket.osgi.application.name</param-name>
       <param-value>someUniqueApplicationName</param-value>
     </init-param>
   </filter>
    The implementation uses a ServiceTracker waiting for a given period for the service to become available.

    You need to register your WebApplication class in the OSGi service registry by any method of your choice, e.g. programmatically in a BundleActivator, or using Declarative Services or Blueprint.
