为什么总说JAVAX包找不到？？？？？_course

用JSP编的在线发送EMAIL的程序，需要调用javabean，但是编译的时候总说JAVAX包找不到，源程序如下： package mail; import java.util.*; import j

javax包到底在哪里？_course

我编写了servlet，编译时总是找不到javax包，我用的是resin212，jdk14。 我在classpath里面已经加了resin/lib了

求问怎么解决？javax.servlet.ServletException_course

idea 中maven 编译报找不到javax.servlet.ServletException的类文件_course

如题，我也尝试通过settings把servlet-api.jar引入，但好像没什么用 /E:/test/gitRepo/SpringMvc/src/main/java/spitter/config/

javax.servlet.*和javax.servlet.http.*包为什么不存在？？？_course

各位能人： 下面为一个servlet例子，但是连编译都不能通过，提示我有以下错误：package javax.servlet does not exist 和javax.servlet.http.*

我的javax.servlet.* 包怎麼找不到啊？_course

我的javax.servlet.* 包怎麼找不到啊？ 我已經把%tomcat_home%\commom\lib中servlet.jar加到classpath中了？ 怎麼回事啊？

ejb3-persistence(找不到javax.persistence.Entity问题解决）下载_course

“Caused by: java.lang.ClassNotFoundException: javax.persistence.Entity”，查找资料发现是缺少jar包. 添加此包就OK了。 更多说

在javax中找不到servet包。_course

我在写程序时遇到引入servlet包出错，在javax中找不到该包。 在tomcat下找到servlet-api.jar后怎么配置才能正确用javax.servlet啊？
