Sorry, I spent so much time hoping to get the example going for you quickly
that I TOTALLY missed the point... My Jersey resource needs access to other
components of the system to construct the response, but when I try to add
@Requires in the resource code it doesn't seem to pick anything up. So I tried
a lot of things with setting up Jersey and wrapping classes, etc. to no avail.
For instance, let's say there is a component that provides the current status:
public interface StatusProvider {
String getStatus();
}
@Component(immediate=true)
@Provides
public class StatusProviderImpl implements StatusProvider {
@Override
public String getStatus() {
return "active";
}
}
@Component(immediate=true)
@Path("status")
public class StatusResource {
@Requires
private StatusProvider status;
@GET
@Produces("text/plain")
public String getStatus() {
return status.getStatus();
}
}
XML Config -
<ipojo>
<instance component="com.sun.jersey.samples.osgihttpservice.
StatusProviderImpl"/>
<instance component="com.sun.jersey.samples.osgihttpservice.StatusResource"/>
<instance component="com.sun.jersey.samples.osgihttpservice.JerseyComponent"/>
</ipojo>
When I fire this up and hit the url, then I get a null pointer for the
StatusProvider.
Hopefully it is just something dead simple that I am overlooking.
Thanks again,
David
