【问题描述】：

我非常需要一个建议，我在哪里出错了

我有 servlet-api.jar @E:\J2EE\apache-tomcat-6.0.18\lib

E:\J2EE\apache-tomcat-6.0.18\lib\servlet-api.jar

我正在尝试运行位于

的 Servlet 类“TouchServlet.java”

E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet\src\com\saravanansivaji\servlet\TouchServlet.java

所以在命令提示符下，

E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet>javac -classpath E:\j2ee\apach e-tomcat-6.0.18\lib\servlet-api.jar src\com\saravanansivaji\servlet\TouchServlet .java

注意：我是从 E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet 执行的

下面是目录结构

E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet> 我在这里

E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet\src\com\saravanansivaji\servlet\TouchServlet.java

E:\J2EE\apache-tomcat-6.0.18\lib\servlet-api.jar

如果我编译，我会收到以下错误

E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet>javac -classpath E:\j2ee\apach
e-tomcat-6.0.18\lib\servlet-api.jar src\com\saravanansivaji\servlet\TouchServlet
.java

试试下面

E:\J2EE\apache-tomcat-6.0.18\webapps\TouchServlet> javac -classpath "E:\j2ee\apache-tomcat-6.0.18\lib\servlet-api.jar" TouchServlet.java
