Java Hibernate ENVERS类加载问题
我正在尝试将Hibernate Envers集成到一个已经开发的应用程序中 我将Hibernate Envers JAR放在一个EAR包中，它抛出了一个关于类装入器和某种冲突的丑陋异常 如果我避免将Envers JAR放在EAR中，并将其放在JBoss的“lib”目录中，那么一切都可以正常运行，但我需要将库与应用程序一起提供，因为我无法访问这个全局“lib”目录 我正在JBoss5.1.0.GA上部署，使用Hibernate3.3.GA和Envers1.2.2.GA 有线索吗 例外情况是：Java Hibernate ENVERS类加载问题,java,hibernate,jboss,hibernate-envers,Java,Hibernate,Jboss,Hibernate Envers,我正在尝试将Hibernate Envers集成到一个已经开发的应用程序中 我将Hibernate Envers JAR放在一个EAR包中，它抛出了一个关于类装入器和某种冲突的丑陋异常 如果我避免将Envers JAR放在EAR中，并将其放在JBoss的“lib”目录中，那么一切都可以正常运行，但我需要将库与应用程序一起提供，因为我无法访问这个全局“lib”目录 我正在JBoss5.1.0.GA上部署，使用Hibernate3.3.GA和Envers1.2.2.GA 有线索吗 例外情况是： 15

在处理多个类加载器时，这看起来像是典型的Java继承问题。您是否尝试过将jboss-classloading.xml添加到EAR META-INF/lib目录中
<classloading xmlns="urn:jboss:classloading:1.0"
parent-first="false"
domain="DefaultDomain"
top-level-classloader="true"
parent-domain="Ignored"
export-all="NON_EMPTY"
import-all="true">
</classloading>
