jar冲突了

不知道那个jar包冲突

我在网上查找对于的解决方案如下： The validator class: "org.apache.taglibs.standard.tlv.JstlCoreTLV" has failed with the following exception: "java.lang.ClassCastException: weblogic.xml.jaxp.RegistrySAXParserFactory cannot be cast to javax.xml.parsers.SAXParserFactory". <%@page contentType="text/html;charset=utf-8"%> ^---------------------------------------------^ If your webapplication is using the following JAR file : xml-apis-1.x.x then please remove it from your WEB-INF/lib directory. 按照这个方法去弄，也解决不了问题。

有高手知道吗？搞了好几天了。。。。

[quote=引用 3 楼 u011459439 的回复:] If your webapplication is using the following JAR file : xml-apis-1.x.x then please remove it from your WEB-INF/lib directory. [quote] 删掉xml-apis.jar也不行吗？

查了好多解决办法，主要原因是weblogic 的jar 包与程序中的jar包冲突，prefer-web-inf-classes设置为true 引起的需要删除xml-apis.jar这个jar包才可以。 ------但删除这个jar包后，又不能解析hibernate Queries
