我已经检查了几乎所有可能发生错误的帖子。我已经编辑了几乎所有在线提供的环境变量。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。罐;

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

我真的很困惑如何继续！一直困在这一点!!

Answer 1

您应该使用;来分隔Windows中的类路径条目

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系列环境使用冒号:来分隔类路径条目

错误：javax.servlet不存在
