為什么我的 javamail 程序沒有通過 jdeveloper 運行？

Question

我正在開發 Oracle MAF 應用程序並使用 Java 郵件 API 發送 Outlook 會議請求。 我可以從 java 命令行成功發送郵件，但是當使用移動應用程序嘗試相同時，代碼不會在創建“MimeMessage”類對象之后進行。

MimeMessage message = new MimeMessage(mailSession);

printStackTrace() 顯示此異常：

06-09 10:54:43.146: D/JVM(16075): [SEVERE - oracle.adfmf.framework - Utility - invoke] InvocationTargetException 錯誤：錯誤 [oracle.adfmf.framework.exception.AdfException] - 調用方法'sendMail 時出錯' 在 'class beans.UtilBean'

06-09 12:14:07.466: I/System.out(3760): [嚴重 - oracle.adfmf.framework - adf.mf.internal - logError] 請求：{"classname":"oracle.adfmf.framework.api .Model","method":"processBatchRequests","params":[false,[{"classname":"oracle.adfmf.framework.api.Model","method":"evaluateMethodExpression","params":[ "#{UtilBean.sendMail}",[{".type":"oracle.adfmf.amx.event.ActionEvent"}],"void",["oracle.adfmf.amx.event.ActionEvent"]]}] ]} 異常：{"message":"在'class beans.UtilBean'"中調用方法'sendMail'時出錯",".exception":true,"severity":"ERROR",".type":"oracle.adfmf。 framework.exception.AdfException"}

        } catch (MessagingException e) {
            throw new RuntimeException(e);

    }

    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);
        }
    }
}

在電子郵件類中，我在創建“MimeMessage”類對象之前和之后添加了打印語句，我能夠在 logcat 中看到第一個打印但不是第二個。

在 Web 邏輯服務器上部署 Java 項目作為 Web 服務（作為 .war 包）對我有用。
