昨天上午启动resin的时候出现org.xml.sax.SAXNotRecognizedException

严重: Unable to initialize Struts ActionServlet due to an unexpected exception or error thrown, so marking the servlet as unavailable.  Most likely, this is due to an incorrect or missing library dependency.

问题：org.xml.sax.SAXNotRecognizedException不能解析struts.xml配置文件。

解决问题1.重新导入jar包，防止jar有冲突的情况。

            2.自己仔细看看下关于resin指定jdk版本是否配置

SAX是解析XML文件的一种方式！
