@ApplicationPath may only be applied to a subclass of Application :

Identifies the application path that serves as the base URI for all resource URIs provided by Path. May only be applied to a subclass of Application.

For this one :

@ApplicationPath("/t")
public class App extends Application{

}

It is fine.

But it is not the case for ContactController that should not declared with @ApplicationPath :

@ApplicationPath("/t1")
public class ContactController {

but with @Path (without leading slash):

@Path("t1")
public class ContactController {

Extract of Path javadoc :

Identifies the URI path that a resource class or class method will serve requests for. .... Paths are relative. For an annotated class the base URI is the application path, see ApplicationPath.

At last, you should remove the leading slash for the @Path of your REST methods : @Path("/t1")

It is not required as the specification of Path explains that leading / are ignored and that base URI are handled as if a / was added.

For the purposes of absolutizing a path against the base URI , a leading '/' in a path is ignored and base URIs are treated as if they ended in '/'

So these :

@Path("/hi")
...
@Path("/t2")

should be replaced by :

@Path("hi")
...
@Path("t2")
