Answer 1

用的tomcat7？Eclipse内核是Eclipse3.5.* 版本
那就用下面的解决办法
一、打开myeclipse，Preferentces->MyEclipse->Servers->Tomcat->Tomcat 6.x
,载入Tomcat7，在"Paths"下，点击“Add JAR/ZIP”,加载tomcat7下的……/bin/tomcat-juli.jar。点击“OK”.

二、可以设置环境变量添加classpath到CATALINE_HOME/bin/tomcat-juli.jar，Tomcat默认启动会自动加载。
classpath=……;%CATALINA_HOME%\bin\tomcat-juli.jar;
