I've looked at this for two hours, and I can't see why this simple injection
does not work.
Any ideas? I'm using Jersey 1.5, under Tomcat 7 (the error happens under
Jetty 6, too).
If I remove the @Context injection, the GET works fine. I've never seen
anything like this in two years of using Jersey. Obviously I'm blanking on
something important.
The resource class:
import javax.servlet.ServletContext;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Context;
@Path("testme")
public class TestResource {
public TestResource(@Context ServletContext servletContext) { }
@GET
public String testGet() { return "hello"; }
}
The service invocation:
curl -i
http://localhost:8080/server/ds/testme
The exception:
