导入现有证书（如果有的话）
keytool -import -alias {myalias} -file {mycertificate}（由于我没有适当的证书，因此无法测试此命令）keytool -list查看您的新证书keytool -export -alias {myalias} -file mycertificate.crt创建并导入新的（测试）证书
keytool -genkey -alias {myalias} -keyalg RSA -validity 365keytool -list查看新证书keytool -export -alias {myalias} -file mycertificate.crt构建并打包应用程序
javac来构建您的 MIDlet，特别注意您的类路径和 bootclasspath 选项（否则预验证将失败）。我还将目标设置为 1.1，源设置为 1.3MIDlet-Jar-URL、MIDlet-Jar-Size、MIDlet-Permissions 我们还包括 MIDlet-Icon、MicroEdition-Configuration、MicroEdition-Profile、MIDlet-Name、MIDlet-Push-1、MIDlet-Icon、MIDlet-Description 和 MIDlet-版本

在手机上安装证书
右键单击该文件并选择“发送到蓝牙设备”，
您也应该能够通过电缆或红外线 (IR) 发送文件。注意：我
无论如何，还没有找到在 Series 40 手机上导入证书的方法
“应用程序安装”。在我的手机（诺基亚 6680）上，它位于
工具->设置->证书管理->信任设置，我开启了
一切，但我认为“应用程序安装”就是您所需要的
常见问题
MIDlet-Permissions中的换行符可能会导致问题，但在诺基亚 6680/6630/6230i 上对我来说似乎没问题（可能与固件有关？）MIDlet-Permissions属性是造成很多问题的原因（特别是因为文档经常错误/丢失或因手机而异），请尝试先将其忽略，然后在一次一个。有些手机会抱怨它们不支持的权限，有些手机会忽略它们信任域

Installing the Certificate on the phone
this by right clicking the file and selecting "Send to Bluetooth Device",
you should be able to send files by cable or Infra Red (IR) too. NB: I
haven't found anyway of importing a certificate on a Series 40 phone
"Application Installation". On my phone (Nokia 6680) this is under
Tools->Settings->Certificate Management->Trust Settings, I turned on
everything but I think "Application Installation" is all you need
Common Problems
MIDlet-Permissionscan cause problems but it seems ok to me on Nokia 6680/6630/6230i (could be firmware dependent?)MIDlet-Permissionsattribute is the cause of a lot of problems (especially since the documentation is often wrong/missing or different depending on the phone), try leaving it out first and add permissions in one at a time. Some phones will complain about permissions they don't support, some will ignore themTrust Domains
