javax.ws.rs.ProcessingException: could not find writer for content-type application/x-www-form-urlencoded type

I'm sending POST request using "resteasy-client" library in MediaType.APPLICATION_FORM_URLENCODED_TYPE.

Sample Code : 

String serviceUrl = "URL";

    ConnectRequest connectRequest = new ConnectRequest();
    connectRequest.setUsername("");
    connectRequest.setPassword("");
    connectRequest.setScope("bearer");
    connectRequest.setGrant_type("");

    Entity<ConnectRequest> entity = Entity.entity(connectRequest,
                MediaType.APPLICATION_FORM_URLENCODED_TYPE);

    ResteasyClient client = new ResteasyClientBuilder().build();
    ResteasyWebTarget target = client.target(serviceUrl);

    Response response = target.request().post(entity);

    System.out.println("RESP : "+response.toString());

Connection is working fine and sending correct response while requesting using POSTMAN

enter image description here

But after requesting using the program it creates error as

Response :

javax.ws.rs.ProcessingException: could not find writer for content-type application/x-www-form-urlencoded type

Please help...

I created a set of reader/writers you can import that handle automatic binding of form encoding to java objects: https://github.com/exabrial/form-binding it's a little easier than creating an instance of a Form.

You can't use a POJO to send application/x-www-form-urlencoded. You need to use the javax.ws.rs.core.Form class.

Form connectRequest = new Form()
    .param("username", "...")
    .param("password", "...")
    .param("client_id")
    ...;

You can also use Entity.form(connectionRequest), which is shorthand so you don't have to use the MediaType.APPLICATION_FORM_URLENCODED_TYPE.

As an aside, see this also for parsing the response. You won't need the dependency. You already have the one for RESTEasy.
