jdk与tomcat环境变量配置

1.配置JDK

需要在"http://www.oracle.com/technetwork/java/javase/downloads/index.html" 下载JDK，然后安装在自定义文件夹下面，此处安装在“C:\MYOWN_THINGS\software_install\jdk1.7”，安装好JDK后，再配置JDK的环境变量：

在“我的电脑”上点右键—>“属性”—>“高级”—> “环境变量(N)”。

新建系统变量JAVA_HOME：C:\MYOWN_THINGS\software_install\jdk1.7；

新建系统变量CLASSPATH：.;%JAVA_HOME%/lib;（注意：点号表示当前目录，不能省略）

在系统变量Path的值的前面加入以下内容：%JAVA_HOME%/bin;(注意:这里的分号不能省略)

2.配置Tomcat

在"http://tomcat.apache.org/"下载好tomcat，此处用的是apache-tomcat-7.0.11-windows-x86.zip，这个版本也是免安装的，直接解压到自定义目录就可以了，此处用的是"C:\MYOWN_THINGS\software_install\apache-tomcat-7.0.11",安装好Tomcat后，再配置Tomcat的环境变量：

在“我的电脑”上点右键—>“属性”—>“高级”—> “环境变量(N)”。

新建系统变量CATALINA_HOME：C:\MYOWN_THINGS\software_install\apache-tomcat-7.0.11

在系统变量CLASSPATH的值的后面加入：%CATALINA_HOME%/lib;

在系统变量Path的值中"%JAVA_HOME%/bin;"的后面加入以下内容：%CATALINA_HOME%/bin;

3.测试JDK

打开cmd进行测试JDK是否配置成功：

分别输入java与javac，现在出下面的东西则配置成功，有的人输入javac之后现在的是中文版的，这个是正常的哈。

C:\Documents and Settings\Administrator>java
