我正在为 Netbeans 使用 CodeNameOne 插件，在运行我的应用程序时，我需要发送一封电子邮件。我有以下用于 Windows 程序的代码，但是我认为某些包与 CodeNameOne 不兼容：
package userclasses;
import com.sun.mail.smtp.SMTPTransport;
import java.security.Security;
import java.util.Date;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
/**
*
* @author user
*/
public class GoogleMail {
public GoogleMail() {
}
/**
* Send email using GMail SMTP server.
*
* @param username GMail username
* @param password GMail password
* @param recipientEmail TO recipient
* @param title title of the message
* @param message message to be sent
* @throws AddressException if the email address parse failed
* @throws MessagingException if the connection is dead or not in the connected state or if the message is not a MimeMessage
*/
public static void Send(final String username, final String password, String recipientEmail, String title, String message) throws AddressException, MessagingException {
GoogleMail.Send(username, password, recipientEmail, "", title, message);
}
/**
* Send email using GMail SMTP server.
*
* @param username GMail username
* @param password GMail password
* @param recipientEmail TO recipient
* @param ccEmail CC recipient. Can be empty if there is no CC recipient
* @param title title of the message
* @param message message to be sent
* @throws AddressException if the email address parse failed
* @throws MessagingException if the connection is dead or not in the connected state or if the message is not a MimeMessage
*/
public static void Send(final String username, final String password, String recipientEmail, String ccEmail, String title, String message) throws AddressException, MessagingException {
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
// Get a Properties object
Properties props = System.getProperties();
props.setProperty("mail.smtps.host", "smtp.gmail.com");
props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
props.setProperty("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.port", "465");
props.setProperty("mail.smtp.socketFactory.port", "465");
props.setProperty("mail.smtps.auth", "true");
/*
If set to false, the QUIT command is sent and the connection is immediately closed. If set
to true (the default), causes the transport to wait for the response to the QUIT command.

props.put("mail.smtps.quitwait", "false");
Session session = Session.getInstance(props, null);
// -- Create a new message --
final MimeMessage msg = new MimeMessage(session);
// -- Set the FROM and TO fields --
msg.setFrom(new InternetAddress(username + "@gmail.com"));
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipientEmail, false));
if (ccEmail.length() > 0) {
msg.setRecipients(Message.RecipientType.CC, InternetAddress.parse(ccEmail, false));
}
msg.setSubject(title);
msg.setText(message, "utf-8");
msg.setSentDate(new Date());
SMTPTransport t = (SMTPTransport)session.getTransport("smtps");
t.connect("smtp.gmail.com", username, password);
t.sendMessage(msg, msg.getAllRecipients());
t.close();
}
}
在错误中，它说'找不到符号导入 java.util.properties 和 java.Security 和错误：包 com.sun.net.ssl.internal.ssl 不存在 Security.addProvider(new com.sun.net.ssl .internal.ssl.Provider());
有什么解决方法，或者我可以使用的任何其他代码吗？
提前致谢，
