猫池二次开发错误，求高人指点。
0 [Thread-1] WARN org.smslib - GTW: 短信猫: Cannot understand SIMPIN response: ERROR, will wait for a while...
运行发短信程序出这样的错误
源码：
Service srv;
OutboundMessage msg;
OutboundNotification outboundNotification = new OutboundNotification();
System.out.println("Example: Send message from a serial gsm modem.");
System.out.println(Library.getLibraryDescription());
System.out.println("Version: " + Library.getLibraryVersion());
srv = new Service();
SerialModemGateway gateway = new SerialModemGateway("短信猫", "COM3", 9600, "Wavecom", "M1306B");//115200是波特率，一般为9600。可以通过超级终端测试出来
gateway.setInbound(true);
gateway.setOutbound(true);
gateway.setSimPin("0000");
gateway.setOutboundNotification(outboundNotification);
srv.addGateway(gateway);
srv.startService();----运行到这句出上面的错误。
System.out.println("Modem Information:");
System.out.println(" Manufacturer: " + gateway.getManufacturer());
System.out.println(" Model: " + gateway.getModel());
System.out.println(" Serial No: " + gateway.getSerialNo());
System.out.println(" SIM IMSI: " + gateway.getImsi());
System.out.println(" Signal Level: " + gateway.getSignalLevel() + "%");
System.out.println(" Battery Level: " + gateway.getBatteryLevel() + "%");
System.out.println();
// Send a message synchronously.
msg = new OutboundMessage(phone, content);
msg.setEncoding(MessageEncodings.ENCUCS2);//这句话是发中文短信必须的
srv.sendMessage(msg);
System.out.println("Now Sleeping - Hit <enter> to terminate.");
srv.stopService();
System.out.println("over le"); --------------------编程问答-------------------- 最好找找原厂有没有开发指南吧。
错误是：Cannot understand SIMPIN response: ERROR
那么考虑把这句话注释掉试试看：
// gateway.setSimPin("0000"); --------------------编程问答-------------------- 除 --------------------编程问答-------------------- sim卡的初始pin密码不一定是0000，如果是0000应该没错，我就是这样设置的，连接正常 --------------------编程问答-------------------- sim卡的初始pin密码不一定是0000 --------------------编程问答--------------------

Caught java.lang.ClassNotFoundException: gnu/io/RXTXCommDriver while loading driver gnu.io.RXTXCommDriverorg.smslib.GatewayException: Comm library exception: java.lang.reflect.InvocationTargetException
调试后又开始报这样的错误，代码没变，求指点。 --------------------编程问答-------------------- 除 --------------------编程问答-------------------- 除 --------------------编程问答-------------------- 有谁解决了吗？在线等啊
