Accepted Answer

You should further study the API documentation for Jersey client (https://jersey.java.net/documentation/latest/user-guide.html#client). In a first glance you seem to be making a mistake on defining the `WebTarget`, namely you need to define the `target` (web service endpoint) and then the `resource` (specific resource you want to interact with), so you should have something like this:

```
Client client = ClientBuilder.newClient();
WebTarget target = client
    .target("http://localhost:8080/ProJrsRi_HelloRest2/rest").path("hello");
```

Probably this is the reason why you can see the results on browser but not in your Java application...

You can also find some very good examples of code in the documentation.

HTH.
