JDK 环境变量配置 问题 高手请进

[kkwwk]

这是Path 环境变量的值
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\;C:\Program Files\Microsoft SQL Server\90\DTS\Binn\;C:\Program Files\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\;C:\Program Files\Samsung\Samsung PC Studio 3\;C:\Program Files\Common;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;C:\ProgramFiles\Thunder Network\KanKan\Codecs

这是ClassPath 环境变量的值
%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar

这是JAVA_HOME 环境变量的值
C:\Program Files\Java\jdk1.6.0_01\

大家看看 有错么？？谢谢

你在命令行里运行这个
java -version
如果可以出来就行了

我的jsp页面代码也没错啊 是不是要配置 jre 环境变量啊？？ 请指教 谢谢

你的classpath的环境变量前面要加上.;的，你在google里搜索会有很多的解释，你去看下哈
