Hi,
For getting the content of the response you should consume the response entity.
just inspect the values inside this entity and you'll find a json containing the serialised response of the invoked method.
About 415 error. You have to be sure you post data using the proper format.
Verify what type should have the object expected as parameter in the invoked method and post such an object.

Thank you very much for the advice!

Solution 1:
<java>
package clasesParte2;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.filter.HTTPBasicAuthFilter;
import com.sun.jersey.api.client.filter.LoggingFilter;

public class test1GetFunciona {

private static String REST_URI = "http://localhost:8080/activiti-rest/service/";

   public static void main(String[] args) {
   try {
    Client client = Client.create();

    WebResource webResource = client.resource(REST_URI+"runtime/tasks/20005");

    final HTTPBasicAuthFilter authFilter = new HTTPBasicAuthFilter("kermit", "kermit");
       client.addFilter(authFilter);
       client.addFilter(new LoggingFilter());

    ClientResponse response = webResource.accept("application/json")
                     .get(ClientResponse.class);

    if (response.getStatus() != 200) {
       throw new RuntimeException("Failed : HTTP error code : "
     + response.getStatus());
    }

    String output = response.getEntity(String.class);

      //Me muestra el tipo de error o si salio bien
             System.out.print(response.getStatus());
             System.out.println(" "+response.getStatusInfo());
             System.out.println("—————————————-");

    System.out.println("Output from Server …. \n");
    System.out.println(output);

     } catch (Exception e) {
            e.printStackTrace();
     }
   }
}
</java>
