然而在eclipse里却显示
servlet cannot be resolved to a type
servlet.http cannot be resolved to a type
找了半天资料才知道jdk 里不包括servlet-api.jar这个包，于是到tomcat里找到这个包复制到jdk\jre\lib下
再设置classpath,结果还是无济于事,后来闯进一个英文论坛看到似乎好像说工程里的路径权限高，并且eclipse并到classpath里寻找jar位置，所以我就到我的java项目里
项目名–>右键
Property–>选择
Java Build Path–>选择
Add External JARs–>选择
把servlet-api.jar的路径输入即可 该包在tomcat里有 搜索即可找到
