hibernate - JBoss AS 7 迁移 - java.lang.ClassNotFoundException : org. hibernate.validator.ClassValidator

Question

我有一个在 JBoss AS 4.2.3 上运行的应用程序，我正在尝试将它迁移到 JBoss AS 7.0.2。我也在将 seam 从 2.1.1 升级到 2.2.2。我已经解决了一些类未找到的异常，但我仍然坚持
java.lang.ClassNotFoundException: org.hibernate.validator.ClassValidator
我的完整堆栈跟踪如下。

我对 AS 7 中的新类加载器不是很清楚。Hibernate 4 是否适用于 seam 2.2.2？我尝试在 jboss-deployment-structure.xml 中指定导出以使用 org.hibernate 和 org.hibernate.validator。但是，当我查看这些位置的 jar 时，我没有看到 ClassValidator 类...

我还尝试将 hibernate 3 jars 添加到 EAR/lib 并在 list 中指定它们，但这不会改变任何东西。我看到 hibernate 3 hibernate-validator.jar 确实包含 classValidator 类，但它仍然没有找到它。

更新我也试过 hibernate-validator-legacy-4.0.2.GA.jar

hibernate-annotations-3.4.0.GA.jar
hibernate-commons-annotations-3.1.0.GA.jar
hibernate-core-3.3.0.SP1.jar
hibernate-validator-3.1.0.GA.jar

JBoss 7 中的类加载模型发生了变化。它隐藏了许多未明确声明的内容。
