Here's an example with query parameters and a check for the HTTP response code, which is handy for failing fast and avoiding stack traces from the JSON mapper, often hiding the real cause:

Response response = null;
try {
  response = target.path("apiMethod")
                .queryParam("stringParam", "test")
                .queryParam("booleanParam", Boolean.FALSE)
                .request().accept(MediaType.APPLICATION_JSON).get();

  if (response.getStatus() == Response.Status.BAD_REQUEST.getStatusCode()) { // HTTP 400
    throw new BadRequestException("invalid parameters!");
  } else if (response.getStatus() == 
    Response.Status.NOT_FOUND.getStatusCode()) {  // HTTP 404
        throw new NotFoundException("resource was not found on server!");
  }

    List result = response.readEntity(new GenericType>(){});
    return result;
} finally {
  if (response != null) {
    response.close();
  }
}
