Jersey REST get returns java.lang.NoSuchMethodError

Question

I'm trying to get a response from a working REST webservice.

I have come up with the following looking at the documentation:

void postRest()
{
    Client client = ClientBuilder.newClient();
    WebTarget webTarget = client.target("http://localhost:8080/TestApplication/");
    WebTarget resourceWebTarget = webTarget.path("webresources");
    WebTarget peopleWebTarget = resourceWebTarget.path("people/get/all");

    Invocation invocation = peopleWebTarget.request("text/xml").header("Content-Type", "application/xml").buildGet();
    String response = invocation.invoke(String.class);

    System.out.println(response);
}

However I am returned a not very friendly:

I'm using NetBeans and didn't add any library as it seems the GlassFish Server comes with javax.ws.rs-api.jar which make the above run.

Do I need to add Jersey.jar as well inside libraries or am I missing something? Thank you

Seems Jersey developers are very maven-centric and discourage including the jars manually, so if you're not using maven but instead are including jars inside NetBeans you'll need to add the whole content of jaxrs-ri, including jars inside ext/ directory for the above code to run.

On a side note if you're using client and server side of jersey inside the same project the manual inclusion of jars may break he server side, so better keep them separate!
