严重: Error filterStart

2014-7-10 23:12:23 org.apache.catalina.core.StandardContext startInternal

严重: Context [/FirstSSH] startup failed due to previous errors

2014-7-10 23:12:23 org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks

严重: The web application [/FirstSSH] created a ThreadLocal with key of type [com.sun.faces.util.Util$1] (value [com.sun.faces.util.Util$1@5e6a13]) and a value of type [java.util.HashMap] (value [{com.sun.faces.patternCache={ = }}]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

2、错误原因

     通过这个“Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang3.StringUtils”，可知这个缺少commons-lang3-3.1.jar包

3、解决的方法

     将“commons-lang3-3.1.jar”复制到文件夹lib文件夹
