JSON メッセージを消費して pojo オブジェクトに挿入する単純なサンプルを作成しようとしています。

私は、JavaEE7 をサポートする Netbeans 開発ビルドと最新の Glassfish 4 昇格ビルドを使用しています。

json メッセージで Post メソッドを呼び出すと、ログにスタック トレースが記録されます。この時点で、私が何か間違ったことをしているかどうかはわかりません。jax-rs 2でうまくいくと思っていました。

助けていただければ幸いです。

ここにスタックトレースとソースコードがあります。

JAX-RS 2.0 では、Jersey Client API ではなく、標準の JAX-RS Client API を使用します。したがって、次のようなものです：

public static void main(String[] args){
    javax.ws.rs.client.Client client = javax.ws.rs.client.ClientBuilder.newClient();

    User user = new User();
    user.name="name1";
    user.lastname="lastname2";

    javax.ws.rs.client.WebTarget myResource = client.target("http://localhost:8080/WebApplication1/resources");
    myResource.request(MediaType.APPLICATION_JSON)
        .post(user);

    client.close();
}

この場合、Jersey Client API が機能しなかった理由はわかりません。

詳細については、クライアント API に関する Java EE 7 チュートリアルの章を参照してください。
