Question

我正在开发Oracle MAF应用程序并使用Java mail API发送Outlook会议请求。我可以从java命令行成功发送邮件，但是当使用移动应用程序尝试相同时，代码不会在创建“MimeMessage”类对象的地方之后。

MimeMessage message = new MimeMessage(mailSession);

printStackTrace（）显示此异常：

06-09 10：54：43.146：D / JVM（16075）：[SEVERE - oracle.adfmf.framework -   实用程序 - 调用] InvocationTargetException错误：错误   [oracle.adfmf.framework.exception.AdfException] - 错误调用   'class beans.UtilBean'中的方法'sendMail'

    private class SMTPAuthenticator extends javax.mail.Authenticator {
        public PasswordAuthentication getPasswordAuthentication() {
            String username = SMTP_AUTH_USER;
            String password = SMTP_AUTH_PWD;
            return new PasswordAuthentication(username, password);
        }
    }
}

在Email类中，我在创建“MimeMessage”类对象之前和之后添加了print语句，我能够在logcat中看到第一个打印而不是第二个打印。

在Web逻辑服务器上部署java项目作为Web服务（作为.war包）对我有用。

为什么我的javamail程序没有通过jdeveloper运行？
