.ClassCastException：org.apache.xerces.jaxp.DocumentBuilderFactoryImpl无法转换为javax.xml.parsers.DocumentBuilderFactory

Question

我正在将Weblogic服务器从9升级到10.3.6。当我试图部署我的耳朵应用程序，并得到以下例外。

我尝试了各种各样的东西，包括添加weblogic-application.xml，但它仍然无法正常工作。

<?xml version="1.0" encoding="UTF-8"?> 
    <weblogic-application> 
<xml> 
<parser-factory> 
    <saxparser-factory> 
     org.apache.xerces.jaxp.SAXParserFactoryImpl 
    </saxparser-factory> 
    <document-builder-factory> 
     org.apache.xerces.jaxp.DocumentBuilderFactoryImpl 
    </document-builder-factory> 
    <transformer-factory> 
     org.apache.xalan.processor.TransformerFactoryImpl 
    </transformer-factory> 
    </parser-factory> 
</xml> 

<prefer-application-packages> 
<package-name>org.apache.xerces.parsers.*</package-name> 
</prefer-application-packages> 
</weblogic-application> 

我weblogic.xml中有

<prefer-web-inf-classes>true</prefer-web-inf-classes> 

这是我的pom.xml的一部分：

<dependency> 
<groupId>xerces</groupId> 
<artifactId>xercesImpl</artifactId> 
<version>2.8.1</version> 
<scope>runtime</scope> 
</dependency> 

请帮助。谢谢！

我回答我的问题：

下面的链接启发了我解决这个问题的：

Dealing with "Xerces hell" in Java/Maven?

Basiclly我已删除XML的API，并在pom.xml中xmlParserAPIs的所有依赖。问题已解决。根本原因是我的类路径不应包含导致与Weblogic应用程序服务器存在库冲突的任何javax库。希望能帮助到你。
