我先装的jre-6-windows-i586.exe
然后jre-6-windows-i586.exe然后下载的javacomm20-win32.zip按照他的安装文档设置环境变量等。Copy win32com.dll to your <JDK>\bin directory. Copy comm.jar to your <JDK>\lib directory.
Copy javax.comm.properties to your <JDK>\lib directory.
Add comm.jar to your classpath
/*错误在这里
Several serial port sample applications are provided with this release. One of them is BlackBox. To run BlackBox, first add BlackBox.jar to your classpath: C:\>set CLASSPATH=c:\commapi\samples\Blackbox\BlackBox.jar;%CLASSPATH% Now you can run BlackBox: C:\>java BlackBox 当运行完之后。
Exception in thread "main" java.lang.NoClassDefFoundError: javax/comm/CommPort请问怎么回事

classpath指向的因是jre对应目录.
