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。。。
------解决方案--------------------
试试copy一份至 jdk\jre\lib,
classpath指向的因是jre对应目录.
