我是学习java和nfc的新手.实际上我真的需要一些关于我的作业"NFC编程"的帮助.我尝试本教程http://open-nfc.org/wp/editions/sdk-edition/creating-a-java-example/,我仍然收到此错误信息:

Start failed !
NfcException : Error while starting the NFC Manager - Caused by NFC error DRIVER
at org.opennfc.NfcManager.start(Unknown Source)
at org.opennfc.NfcManager.getInstance(Unknown Source)
at example.Example.main(Example.java:26)
Exception in thread "main" java.lang.IllegalStateException
at org.opennfc.NfcManager.stop(Unknown Source)
at example.Example.main(Example.java:36)

实际上,我想要运行的是open-nfc的这个示例代码

NfcManager mgt = NfcManager.getInstance(null);
try {
  System.out.println(mgt.getProperty("open_nfc.version"));
  System.out.println(mgt.getProperty("nfcc.firmware_version"));
} finally {
  try {
    mgt.stop();
  } catch(NfcException e) {
    System.out.println("Error :" + e.getMessage());
  }
}

我已经启动了连接中心,nfc模拟器和服务器移植.我有一台设备QPROX QP3000,已连接到我的电脑.我正在使用eclipse juno和windows 7.
