JBoss 5 如何解决 Failed to create a new SAX parser

JBoss 5 启动报错了：
org.jboss.xb.binding.JBossXBRuntimeException: Failed to create a new SAX parser
怎么解决？

找了网上的回答是删除项目的lib文件夹下面的三个文件：xml-apis.jar、xerces-2.4.0.jar、xercesImpl.jar

可是我并没有发布项目，只是安装好jboss就启动一下看看。也没有找到所谓的这几个文件啊。

请帮帮忙看看怎么解决。
代码：

解决办法：删掉项目中的xerces-2.6.2.jar和xml-apis.jar两个文件！
