我正在尝试测试Java Card小程序以建立与模拟器的连接,例如cref:
try {
sckClient = new Socket("localhost", 9025);
InputStream is = sckClient.getInputStream();
OutputStream os = sckClient.getOutputStream();
cad = CadDevice.getCadClientInstance(CadDevice.PROTOCOL_T0, is, os);
} catch (Exception e) {
System.out.println("error");
return;
}
try {
cad.powerUp();
} catch (IOException e) {
e.printStackTrace();
} catch (CadTransportException e) {
System.out.println("error");
try {
sckClient.close();
} catch (IOException e1) {
e1.printStackTrace();
}
return;
}
我的代码卡在powerUp
中,没有任何错误或异常。
我正在使用 Java Card Development Kit 3.0.5u1
