Please do not consider it as duplicate request as i have gone through all the post in stackoverflow, none of them answered. no response i found.

Issue is :

I am facing a very weird issue making a GET request with same piece of code via standalone application (inside main()). It works where as if the same code is put in Java EE app and deployed on a wildfly 10 server, it gives Error

"Unable to find a MessageBodyReader of content-type text/html and type interface java.util.List"

Code:

ClientConfig configuration = new ClientConfig();
configuration.property(ClientProperties.CONNECT_TIMEOUT, 10000);
configuration.property(ClientProperties.READ_TIMEOUT, 10000);
Client iexRestClient=ClientBuilder.newClient(configuration);
WebTarget webTarget = 
iexRestClient.target("https://api.iextrading.com/1.0/ref-data/symbols/");
Response response = 
webTarget.request().accept(MediaType.APPLICATION_JSON).get(Response.class);
System.out.println("response status "+response.getStatus());
List<IEXTicker> tickers = response.readEntity(new 
GenericType<List<IEXTicker>>(){});
System.out.println("size of tickers "+tickers.size());

Please post your XML as a code block – Chalcocite
I don't have xml.. i want to fetch data from rest end point api.iextrading.com/1.0/ref-data/symbols This is returning json value.. so i have already added my model class – Cawthon
Any help please.. – Cawthon
What happens if you remove those three jars? Alternatively, what happens if you add <scope>provided</scope> to each of those jars? – Rubellite

I had the same problem. It was caused by the server which did not, as expected, return a content-type: application/json, but it returned:

content-type: text/html; charset=UTF-8

I see two options:

1) contact the provider of the service and ask that application/json be returned

2) read the result of your request as a String and manually convert it to an object. Similar to this:

String jsonData = response.readEntity(String.class);
ObjectMapper mapper = new com.fasterxml.jackson.databind.ObjectMapper();
JsonNode jsonNode= mapper.readValue(jsonData, com.fasterxml.jackson.databind.JsonNode.class);

Now, create a List from the jsonNode data...
