Well digging a little bit more, I found this:
I'm putting the equinox servlet as a bundle: so the class:
org.eclipse.equinox.http.servlet.internal.Activator gets started:
public void start(BundleContext context) throws Exception {
startHttpServiceProxy(context);
}
private static synchronized void startHttpServiceProxy(BundleContext
bundleContext) {
context = bundleContext;
Object[] proxyServlets = serviceRegistrations.keySet().toArray();
for (int i = 0; i < proxyServlets.length; ++i) {
ServiceRegistration registration =
registerHttpService((ProxyServlet) proxyServlets[i]);
serviceRegistrations.put(proxyServlets[i], registration);
}
}
Well it assigns the bundlecontext to its internal variable, so far so good.
Problem is when I create the HTTPProxyServlet:
this.delegatee = new HttpServiceServlet();
this.delegatee.init(getServletConfig());
And it gets initiated:
public void init(ServletConfig config) throws ServletException {
super.init(config);
proxyContext = new ProxyContext(config.getServletContext());
Activator.addProxyServlet(this);
}
The Activator is called in a static way, the addProxyServlet methods checks
for a bundlecontext which is null :(, so it never calls the
registerHttpService, which in turns never triggers the Tracker from the
webconsole.
Anyone got a solution for this please?
Regards
