6 years ago 缺少Java串口通信依赖的jar包
下载地址：http://download.csdn.net/detail/kong_gu_you_lan/9611334 内含32位与64位版本
使用方法： 拷贝 RXTXcomm.jar 到 JAVA_HOME\jre\lib\ext目录中； 拷贝 rxtxSerial.dll 到 JAVA_HOME\jre\bin目录中； 拷贝 rxtxParallel.dll 到 JAVA_HOME\jre\bin目录中； JAVA_HOME为jdk安装路径

6 years ago 操作系统和JDK用的是多少位的，RXTX的位数需要和它们相同

6 years ago 是不是java 不应该装在Program Files (x86) 这个文件夹中，而是该 装在Program Files 这个文件夹中？

6 years ago 应该是jdk的原因，等我重装试下
