错误：javax.servlet不存在

Question

我已经检查了几乎所有可能出现的错误的帖子。 Ive编辑了几乎所有在线给出的环境变量 。 这些是我的环境变量：

ANT_HOME = C：\\ Ant9; C：\\ Tomcat7 \\ lib \\ servlet-api.jar

CLASSPATH = C：\\ Program Files \\ Java \\ jdk1.6.0_24 \\ bin; C：\\ Program Files \\ Java \\ jre6 \\ bin; C：\\ Tomcat7 \\ lib \\ servlet-api.jar;

JAVA_HOME = C：\\ Program Files \\ Java \\ jdk1.6.0_24

路径 = C：\\ Program Files \\ Java \\ jdk1.6.0_24 \\ bin

TOMCAT_HOME = C：\\ Tomcat7

你应该用; 在Windows中分隔类路径条目

javac -cp .;C:\\Tomcat7\\lib\\servlet-api.jar DBConnnection.java 。

但是，您使用了逗号, 。 将逗号更改为分号

注意：* nix家庭环境使用冒号:分隔类路径条目
