Answer 1

没有  log4j.properties 文件

Answer 2

可能的原因：1、应用程序正在初始化，暂时不可用2、web.xml文件写了引用连接池的标签 而server.xml文件种没写配置连接池标签3、web.xml配置错误

Answer 3

web.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5"
