我使用Spring MVC，weblogic 10.3.6。
我有一个jsp。 taglib声明是
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%@ page trimDirectiveWhitespaces="true"%>
<!DOCTYPE html>
<html>
<head>
我的项目部署得很好。当我执行它时，我得到一个异常
"java.lang.ClassCastException: weblogic.xml.jaxp.RegistrySAXParserFactory cannot be cast to javax.xml.parsers.SAXParserFactory".
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

我不知道为什么会得到这个例外。
修改
