我部署在WebSphere Application Server 8.5 J2EE Web應用程序不兼容。爲8.5：java.lang.ClassCastException：org.apache.xerces.jaxp.SAXParserFactoryImpl與javax.xml.parsers.SAXParserFactory中
Web應用程序具有包含所有第三方庫的共享庫。所有內部編碼的庫位於WEB-INF/lib文件夾內。
的問題是，在只有一些JSP的是它拋出以下異常。
我認爲它與xercesImpl-2.8.1.jar有關，但我不明白爲什麼它拋出這個異常以及爲什麼它僅在某些頁面投擲。
在tomcat中它工作得很完美。
