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

I have an application running on JBoss AS 4.2.3, and I'm trying to port it to JBoss AS 7.0.2. I also update the seam from 2.1.1 to 2.2.2. I resolved a few class exceptions that were not found, but I was stuck on

java.lang.ClassNotFoundException: org.hibernate.validator.ClassValidator

My full stack trace is below.

I am not very clear about the new class loader in AS 7. Does Hibernate 4 work with 2.2.2? I tried specifying the export in jboss-deployment-structure.xml to use org.hibernate and org.hibernate.validator. However, when I look at banks in these places, I do not see the ClassValidator class ...

I also tried adding hibernate 3 jars to EAR / lib and listing them in the manifest, but that doesn't change anything. I see that hibernate 3 hibernate-validator.jar contains the classValidator class, but it still cannot find it.

UPDATE I also tried 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

The class loading model has been changed in JBoss 7. It hides a lot of things that are not explicitly declared.

You should familiarize yourself with these links:

1 - I solve this problem by declaring the module in jboss7.1.1 2 - modify the MANIFEST.MF file in the lib folder

in the \ jboss-as-7.1.1.Final \ modules \ folder folder, create the following folders:

\ jboss-as-7.1.1.Final \ modules ** org \ sleep mode \ validator \ main **

then I will copy the hibernate-validator-4.2.0.Final.jar file to the main \ folder

then I create the module.xml file in the main folder and change it with the following text:

 <?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>

Your module is now created in jboss modules.

look at this line:

 <module xmlns="urn:jboss:module:1.1" name="org.hibernate.validator">

you must use org.hibernate.validator in the Dependencies section in the MANIFEST.MF file, as shown below:

 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

then your problem should be skipped: D

if you get a ClassNotFoundException message, you must declare the jboss module and use its name in the MANIFEST.MF file.

: D

putting this in persistence.xml, I worked for this error:

 property name="javax.persistence.validation.mode" value="none"
