How are you registering your root resource and provider classes?
You register your @Provider provider classes in the same way as your
@Path root resource classes.
I suspect that you have not registered the ResourceParamInjector.
Notice in the example i sent that the class is annotated with
@Provider and it is picked up by the package scanning:
initParams.put("com.sun.jersey.config.property.packages",
"com.sun.jersey.samples.resourceinject");
You can declare more than one package by using the ";" separator.
Plus you should ensure that your IocComponentProviderFactory returns
"null" for stuff it does not know how to instantiate. If you have
registered your ResourceParamInjector correctly your
IocComponentProviderFactory will get asked to instantiate it, if you
return null, then you defer to another IocComponentProviderFactory
that can instantiate it.
