I now have my little client prototype using ClientBuilder and a
MessageBodyReader to unmarshal form parameters into a POJO. This works fine in
normal circumstances.
When something goes really bad, I don't get a form response, I get an HTML
response, but I've nicely abstracted my media so much, that I now can't easily
get to the plain HTML result.
How can I have both the "happy path", and an error handler that prints out the
plain text of the response?
My present method using the client is this:
--------------------
public StuffResponse validateToken(String token) {
WebTarget target =
client.target(getStuffHostPort()).path(getStuffPath());
Builder request =
target.request(MediaType.APPLICATION_JSON_TYPE);
Form form = new Form();
form.param("TokenID", token);
StuffResponse response = null;
return request.post(Entity.entity(form,
MediaType.APPLICATION_FORM_URLENCODED_TYPE), StuffResponse.class);
}
--------------
When I call it with a "manipulated" environment so the service fails with an
HTML response, I get the following:
---------------
SEVERE: No message body reader has been found for class
com.att.detsusl.stuffrest.StuffResponse, ContentType: text/html
Exception in thread "main" javax.ws.rs.client.ResponseProcessingException: No

----------
The HTML response is not very likely to happen, but when it happens, I'd like
to make sure it gets into the log.
I know that if I instead post without qualifying with the type, like this:
----------------
Response postResponse = request.post(Entity.entity(form,
MediaType.APPLICATION_FORM_URLENCODED_TYPE));
----------------
Then I can get the text of the response. That might not be helpful here.
