org.odata4j.exceptions.UnsupportedMediaTypeException: Unknown content type text/html;charset=UTF-8

[Francisco Amores Torres]

Hello,

I'm very new to odata4j.

I started with a simple Eclipse project which creates a consumer and tries to read the entities

public static void main(String[] args) {

// TODO Auto-generated method stub

// create consumer instance

String serviceUrl = "http://services.odata.org/OData/OData.svc/";

ODataConsumer consumer = ODataConsumers.create(serviceUrl);

             // list category names

for (OEntity category : consumer.getEntities("Categories").execute()) {

  String categoryName = category.getProperty("Name", String.class).getValue();

  System.out.println("Category name: " + categoryName);

}

}

However, i'm getting an exception about unsupported media type:

Exception in thread "main" java.lang.RuntimeException: Expected status OK, found Moved Permanently. Server response:

Am I missing something? any hint is more than welcome.

Thanks

Also, if i switch uri to 

String serviceUrl = "https://services.odata.org/V4/TripPinService/";

Then I get

Hi Francisco,

odata4j to my knowledge is no longer maintained, there has been no traffic in this group during the last 18 months.

Olingo on the other hand is an actively maintained Java library for OData, so I suggest you look into it instead: http://olingo.apache.org/

Kind regards

Ralf
