我错过了一些基本的东西吗？个性洞察

Question

所以这是第一次使用任何 bluemix 服务，我收到以下错误，并且在网上找不到与此相关的任何帮助。 我错过了一些基本的设置吗？

感谢您的帮助。

错误是：

    ProfileOptions options = new ProfileOptions.Builder().text(text).build();
    Profile profile = service.profile(options).execute();

    System.out.println(profile);
}

}

这听起来像是一个类路径问题。当你运行它时，你是否指定了这个类的 jar 在你的类路径中（又名java -cp...）？
