创建的jsp项目，在tomcat打开的时候显示以下错误。初来乍到，请好心专业人士指点。。
严重: The web application [/firstweb] created a ThreadLocal with key of type [com.sun.faces.util.Util$1] (value [com.sun.faces.util.Util$1@130be8c]) 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.
另外，我创建的访问数据库的类，在测试中运转正常，但在servlet中调用类方法会出现以下错误，查了好多方法，始终搞不明白，一并请教。（看到之前有位朋友也遇到这个问题，有人说是jar导入tomcat下的lib文件夹，所以我也把jar包导入了webinfo下面的lib，但仍然搞不定。）

------解决方案--------------------
1 你的一个内部类中使用了线程，它还调用了一个非线程安全的类
2 你在普通项目中默认根路径和Web项目下的默认根路径不一样，你又没写好相对路径，当然报错。
