錯誤：javax.servlet不存在

Question

我已經檢查了幾乎所有可能出現的錯誤的帖子。 Ive編輯了幾乎所有在線給出的環境變量 。 這些是我的環境變量：

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

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

TOMCAT_HOME = C：\\ Tomcat7

我真的對如何進行感到困惑！ 此時被卡住了！！

你應該用; 在Windows中分隔類路徑條目

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

但是，您使用了逗號, 。 將逗號更改為分號

注意：* nix家庭環境使用冒號:分隔類路徑條目
