问题描述

我将Weblogic服务器从9升级到10.3.6。当我尝试部署我的Ear应用程序并遇到异常时。

I am upgrading Weblogic server from 9 to 10.3.6. when I am trying to deploy my ear application and got below exception.

我尝试了各种方法，包括添加weblogic-application.xml，但是

I tried all sorts for things including adding a weblogic-application.xml but it still does not work.

<?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>

我的weblogic.xml具有

my weblogic.xml has

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

这是我pom.xml的一部分：

This is part of my pom.xml:

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

请帮助。谢谢！

推荐答案

我回答我自己的问题：

下面的链接启发我解决此问题：

Below link inspired me of fixing this issue:

处理 Xerces hell在Java / Maven中？

很容易，我删除了pom.xml中所有xml-api和xmlParserAPI的依赖项。该问题已解决。根本原因是我的类路径不应包含任何导致与Weblogic应用服务器冲突的javax库。希望能帮助到你。

Basiclly I have removed all the dependencies of xml-api and xmlParserAPIs in pom.xml. The problem is fixed. The root cause is my classpath should not include any javax libraries which cause the library conflict with Weblogic app server. Hope it helps.
