需要大家的帮忙，我的串口通信问题！
以前开发的时候用的是sun公司的comm.jar开发的串口因为它只支持windows
现在改用包RXTXcomm.jar来替换comm.jar包．但我在linux启动服务的时候报这个错，不知道为什么？希望高手多多指教！错误如下：
15:19:21,442 ERROR [STDERR] java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver

[解决办法]
不知道.up
[解决办法]
这是没找到本地类库所致
你把rxtxParallel.dll,rxtxSerial.dll这两个放到你java的当前目录下(选windows下的)
www.NetJava.cn
[解决办法]
下面有介绍，还有需要的动态库及类库下载
