原因:weblogic使用了自己带的xml解析器造成的ClassCastException
解决方式
1 我的解决方法:由于项目中有个weblogic.jar,实际没有用到,直接删除就行了
2 在WEB-INF下的WebLogic.xml中作设置:prefer-web-inf-classes标签配置weblogic优先使用web程序自带的类库。
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
3 将以下条目添加到 $java.home/lib/jaxp.properties 文件来定义 XML 解析器类：
javax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl javax.xml.xpath.XPathFactory=org.apache.xpath.jaxp.XPathFactoryImpl javax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl javax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
