Hi Dirk,
I've read all of your great blog post. By the way thank you for those .
Unfortunately, in those you do exact the same things as I did in my example.
The servlet looks like this:
@Component(service = Servlet.class, scope = ServiceScope.PROTOTYPE)
public class MyServlet extends HttpServlet{
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
resp.setContentType("text/plain");
resp.getWriter().println("Hello World!");
}
}
and the ServletContextListener like this:
@Component
@HttpWhiteboardListener
public class MySCL implements ServletContextListener {
@Override
public void contextDestroyed(ServletContextEvent arg0) {
System.out.println("Destroyed");
}
@Override
public void contextInitialized(ServletContextEvent arg0) {
System.out.println("Initialized");
}
}
I think by using the new annotations everything should be set up right. The
Servlet works as expected, but the SCL is never called.
In contrast to your blog post examples I didn't use any specific
ServletContext(Helper), but I thought this would lead to using the default
ServletContext. I think in most of my cases I do not need to use a specific
ServletContext,, so the default would be sufficient.
Kind regards,
Thomas
