================================================
以前也遇到过，后来不知道怎么解决的，现在又出现了，求解啊

Answer 1

tomcat中lib默认的包就够了

包不一致导致编译问题，不要轻易把包放tomcat里头
自己项目需要的包，放在自己项目中 的 WEB-INF/lib 目录

不用拷贝到 tomcat 中的lib目录
删除了那些无用的, 重启一下就好了

Answer 2

没有找到相关的类，你确定必要的一类jar文件都导入了吗
上面说是init方法里德错误，初始化的时候出错，可能你的那里配置有问题了

Answer 3

下载javax.jar包 放到bin目录下 在myeclipse中导入.
