配置JDK和Tomcat环境变量

1.安装JDK

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:/Program Files/Java/jdk1.5.0_06；

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)

到这里，JDK安装完毕。

2.安装Tomcat

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：D:/jakarta-tomcat-5.0.30

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

到这里，Tomcat安装完毕。

配置好以上环境变量之后，各系统变量的值如下：

JAVA_HOME:C:/Program Files/Java/jdk1.5.0_06

CATALINA_HOME:D:/jakarta-tomcat-5.0.30

CLASSPATH:.;%JAVA_HOME%/lib;%CATALINA_HOME%/common/lib;

Path:%JAVA_HOME%/bin;%CATALINA_HOME%/bin;%SystemRoot%/system32;%SystemRoot%;%

SystemRoot%/System32/Wbem

-endorseddirs <目录> 覆盖签名的标准路径的位置

-proc:{none,only} 控制是否执行注释处理和/或编译。

-processor <class1>[,<class2>,<class3>...]要运行的注释处理程序的名称；绕过默认

的搜索进程

-processorpath <路径> 指定查找注释处理程序的位置

-d <目录> 指定存放生成的类文件的位置

-s <目录> 指定存放生成的源文件的位置

-implicit:{none,class} 指定是否为隐式引用文件生成类文件

测试Tomcat是否配置成功：

进入Tomcat目录下的bin里面

双击startup.bat

如果显示下列信息就配置成功
