我有一个在JBoss AS 4.2.3上运行的应用程序，我正在尝试将其迁移到JBoss AS 7.0.2。我也将接缝从2.1.1升级到2.2.2。我已经解决了一些未找到的类异常，但我坚持
java.lang.ClassNotFoundException: org.hibernate.validator.ClassValidator
我的完整堆栈跟踪如下。
我对AS 7中的新类加载器不太清楚.Hibernate 4是否适用于seam 2.2.2？我已经尝试在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罐子时，我没有看到ClassValidator类...
我还尝试将Hibernate 3 jar添加到EAR / lib并在清单中指定它们，但这并没有改变任何东西。我看到hibernate 3 hibernate-validator.jar确实包含classValidator类，但它仍然找不到它。
更新我还尝试了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

在JBoss 7中更改了类加载模型。它隐藏了许多未明确声明的内容。
你必须熟悉这些链接：
https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7
答案 1 :(得分：3)
1 - 我通过jboss7.1.1中的declare模块解决了这个问题 2 - 修改lib文件夹中的MANIFEST.MF文件
在\ jboss-as-7.1.1.Final \ modules \文件夹中创建此文件夹：
\ jboss-as-7.1.1.Final \模块**有机\休眠\验证\主**
然后我将文件hibernate-validator-4.2.0.Final.jar复制到main \
的文件夹中然后我在主文件夹中创建文件module.xml并通过以下代码修改它：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.hibernate.validator">
<resources>
<resource-root path="hibernate-validator-4.2.0.Final.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.persistence.api"/>
<module name="javax.validation.api"/>
<module name="javax.persistence.api"/>
<module name="javax.xml.bind.api"/>
<module name="org.jboss.logging"/>
<module name="org.jboss.common-core"/>
<module name="org.joda.time"/>
<module name="org.slf4j"/>
<module name="org.apache.xerces" services="import"/>
<module name="sun.jdk" services="import"/>
</dependencies>
</module>
现在，您的模块是在jboss模块中创建的。
看看这一行：
<module xmlns="urn:jboss:module:1.1" name="org.hibernate.validator">
你必须在MANIFEST.MF文件的Dependencies部分中使用org.hibernate.validator，如下所示：
Manifest-Version: 1.0
Implementation-Vendor: Sahand Samaneh
Implementation-Title: Sahand System Security Product
Implementation-Version: 5.0.0-SNAPSHOT
Implementation-Vendor-Id: com.sahand.product
Built-By: pooladi.morteza
Build-Jdk: 1.6.0_21
Created-By: Apache Maven 3.0.4
Archiver-Version: Plexus Archiver
Dependencies: com.sahand.common.util,com.sahand.common.security,com.sahand.model.common,com.sahand.model.user.management,com.sahand.model.security,com.sahand.security.api,com.sahand.security.persistence,com.sahand.security.service,org.apache.commons.codec,org.slf4j,ch.qos.logback.core,ch.qos.logback.classic,javax.validation.api,org.hibernate.validator
然后你的问题必须通过：D
如果你收到ClassNotFoundException的任何消息，你必须声明jboss模块并在你的MANIFEST.MF文件中使用它的名称。
：d
答案 2 :(得分：-1)
将这个放在persistence.xml中对我有用：
property name="javax.persistence.validation.mode" value="none"
