Question

请高手指教，我的环境变量那里出了问题！我是菜鸟啊！ 输入java时时可以的，输入javac就不行！

CLASSPATH
.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;

JAVA_HOME
C:\Program Files\Java\jdk1.6.0_12

Path
%JAVA_HOME%\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\ThinkPad\Bluetooth Software\;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\Common Files\Lenovo;C:\Program Files\Common Files\Roxio Shared\10.0\DLLShared\;C:\Program Files\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Lenovo\Access Connections\;C:\Program Files\Common Files\Thunder Network\KanKan\Codecs

Answer 1

你也可以这样配:
JAVA_HOME:C:\Program Files\Java\jdk1.6.0_12

CLASS_PATH:.;C:\Program Files\Java\jdk1.6.0_12\lib;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;

PATH:C:\Program Files\Java\jdk1.6.0_12\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\ThinkPad\Bluetooth Software\;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Program Files\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\Common Files\Lenovo;C:\Program Files\Common Files\Roxio Shared\10.0\DLLShared\;C:\Program Files\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Lenovo\Access Connections\;C:\Program Files\Common Files\Thunder Network\KanKan\Codecs
你可以试一下啊

Answer 2

在系统变量加：
JAVA_HOME--------C:\Program Files\Java\jdk1.6.0_12
path---------%JAVA_HOME%\bin;%JAVA_HOME%\lib
CLASSPATH不用管，path后面一堆你不用管，都是别的软件自动添加的环境变量，你在path里只加了bin，缺少lib下的jar包

Answer 3

在CLASSPATH里加上%JAVA_HOME%\jre\lib\rt.jar

Answer 4

名：JAVA_HOME 值: C:\Program Files\jdk1.6.0_11
