Okay forgot the init params code now looks like this:
ServletAdapter adapter = new ServletAdapter();
Injector injector = Guice.createInjector(new MyModule());
GuiceContainer container = new GuiceContainer(injector);
adapter.setServletInstance(container);
GuiceFilter filter = new GuiceFilter();
adapter.addFilter(filter, "guiceFilter", null);
adapter.addInitParameter("com.sun.jersey.config.property.packages",
"com.netdesign.rest");
SelectorThread threadSelector =
GrizzlyServerFactory.create(BASE_URI,
adapter);
But I get a null pointer where the injected property should have been
called:
SEVERE: service exception:
java.lang.NullPointerException

And a little code :
@Path("/myresource")
public class MyResource {
private MessageDao myTest;
// TODO: update the class to suit your needs
// The Java method will process HTTP GET requests
@GET
// The Java method will produce content identified by the MIME Media
// type "text/plain"
@Produces("text/plain")
public String getIt() {
return myTest.getMessage();
}
@Inject
public void setMyTest(MessageDao myTest) {
this.myTest = myTest;
}
}
and the module:
@Override
protected void configure() {
bind(MessageDao.class).to(MyTest.class);
}
