Java JAXB实现中的Jar问题

我试图使用docx4j库操作文档，作为一个独立的程序，该程序运行良好，但当我在jBoss中部署它时，它给出了以下错误

我已经检查并发现jboss类路径中已经存在jaxb-impl.jar

下面是jBoss-deployment-structure.xml

<?xml version="1.0" encoding="UTF-8"?>

    <!-- Make sub deployments isolated by default, so they cannot see each others classes without a Class-Path entry -->

    <!-- This is the top level ear module, which contains all the classes in the EAR's lib folder     -->

看起来您正在使用JBoss 7.1.1？您是否遵循@JasonPlutext？我已经在jBoss库中复制了jaxb实现jar，但由于某些原因，它仍然存在错误。您认为这与多次复制jaxb jar文件有关吗？@JasonPlutext对此有何想法？根据我上面给出的链接，您的WEB-INF/jBoss-deployment-structure.xml包含哪些内容？请将其粘贴到上面的问题中。@JasonPlutext添加了jboss-deployment-structure.xml
