我必须在我的企业应用程序中使用 4.0.1 版的 Hibernate。EAR 被部署到一个 JBoss 6.0 容器中。
ear 文件包含以下休眠 jar：
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-core-4.0.1.Final.jar
hibernate-entitymanager-4.0.1.Final.jar
hibernate-envers-4.0.1.Final.jar
hibernate-envers-4.0.1.Final.jar
hibernate-envers-4.0.1.Final.jar
hibernate-search-analyzers-4.0.0.Final.jar
hibernate-search-engine-4.0.0.Final.jar
hibernate-search-engine-4.0.0.Final.jar
hibernate-validator-4.2.0.Final.jar
根据Upgrade Hibernate version in JBOSS我尝试使用以下 jboss-app.xml 和 jboss-classloading.xml 配置自定义类加载
<!DOCTYPE jboss-app PUBLIC "-//JBoss//DTD J2EE Application 1.4//EN" "http://www.jboss.org/j2ee/dtd/jboss-app_5_0.dtd">
<jboss-app>
<loader-repository>
com.acme.sample:archive=Sample
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
</loader-repository>
</jboss-app>
<?xml version="1.0" encoding="UTF-8"?>
<classloading xmlns="urn:jboss:classloading:1.0"
domain="sample.ear"
export-all="NON_EMPTY"
import-all="true"
parent-first="false">
</classloading>
启动 JBoss 6 容器时，日志文件中出现以下行：
09:49:55,238 INFO [org.hibernate.annotations.common.Version] HCANN000001: Hibernate Commons Annotations {4.0.1.Final}
09:49:55,265 INFO [org.hibernate.Version] HHH000412: Hibernate Core {4.0.1.Final}
似乎已经检测到 Hibernate 4.0.1。但随后发生以下异常：
09:49:55,388 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Start: name=persistence.unit:unitName=sample-SNAPSHOT.ear/lib/persistence_impl-0.0.21-SNAPSHOT.jar#sample state=Create: java.lang.ClassCastException: org.jboss.as.jpa.scanner.HackTLScanner cannot be cast to org.hibernate.ejb.packaging.Scanner

在异常堆栈跟踪中，提到了 hibernate 的 3.6.0.Final 版本。似乎容器仍在尝试使用 JBoss 附带的休眠版本创建 JPA 持久性单元。
谁能给我一个提示，告诉我我做错了什么以及如何配置自定义类加载，以便 JBoss 使用打包在 EAR 文件中的 Hibernate 版本。
