Here's an example of something I'm having a lot of trouble figuring
out how to debug.
ServletAdapter sa = new ServletAdapter();
sa.addInitParameter(PackagesResourceConfig.PROPERTY_PACKAGES,
"my.package.resources");
sa.setContextPath("/");
sa.setServletInstance(new ServletContainer());
//
// Add the authetication filter
//
sa.addInitParameter(ResourceConfig.PROPERTY_CONTAINER_REQUEST_FILTERS,
TAF.class.getName());
TAF is a very simple filter that I wrote just to test
public class TAF implements ContainerRequestFilter {
public TAF()
{
super();
System.err.println("!!!!!!!! FILTER CREATED");
}
@Override
public ContainerRequest filter(ContainerRequest request) {
System.err.println("!!!!!!!!!!!! FILTER INVOKED");
return request;
}
}
I can see it telling me the filter got created (interestingly, this
happens at the first request, rather than immediately upon the server
starting).... but my filter is never getting invoked.
Tracing through the source of grizzly-servlet-webserver and
grizzly-http-servlet is ... challenging. I would love a log.debug()
telling me "Filter not invoked, it hast he wrong XYZ" or something
like that.
What do you recommend as a debugging approach?
