役に立ちましたか？

解決 2

ジャージークライアントに次のJSON構成が欠けていました

    ClientConfig config = new DefaultClientConfig();
    config.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
    client = Client.create(config);

他のヒント

スタックトレースからは、次のように見えます Accept ヘッダーはクライアントから送信されませんでした。ただし、nullpointerexceptionは、私の意見ではサーバーにとって適切なエラーではないため、IBMでPMRを開くことをお勧めします。

あなたがあなた自身のWinkの実装とアプリケーションを使用してJARを持っているとき、私は同様の例外を見てきました。どちらでも解決します

server.xmlからjax -rs機能を削除 - アプリケーションのライブラリと競合します。

また

WebSphere Specに従ってJax-RSアプリケーションを構成し、アプリケーションからWink Jarsを削除しますhttp://www-01.ibm.com/support/knowledgecenter/ssaw57_8.5.5/com.ibm.websphere.nd.multiplatform.doc/ae/twbs_jaxrs_implejaxrsapps_step3.html
