Starting Wicket web application with OSGi HTTP Service

Question

I\'m trying to start a Wicket Application using Felix implementation of OSGi HTTP service, for that I just register the service using WicketServlet with a

Answer 1

The problem here is that Wicket seems to load the applicationClass badly. I have not looked at the code that does this, but I suspect it's using current thread's context classloader.

I did the following to overcome this:

1. Create my own WicketFilter (called MyWicketFilter) and override getClassLoader. This returns this.getClass().getClassLoader().
2. Register the MyWicketFilter as a Filter service to be picked up by the whiteboard http service.

Code for activator start:

Hashtable<String, String> props = new Hashtable<String, String>();
props.put("pattern", "/.*");
props.put("init.applicationClassName", MyApplication.class.getName());

final MyWicketFilter service = new MyWicketFilter();
context.registerService(Filter.class.getName(), service, props);

Code for MyWicketFilter:

public final class MyWicketFilter
    extends WicketFilter
{
    @Override
    protected ClassLoader getClassLoader()
    {
        return this.getClass().getClassLoader();
    }
}

You can also use WicketServlet, but this involves overriding newWicketFilter and return MyWicketFilter from here.
