Deployment error:
JBAS011466: PersistenceProvider ‘org.eclipse.persistence.jpa.PersistenceProvider’ not found

1.
make sure persistence.xml persistence-unit includes <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

2.
Download EclipseLink Installer http://www.eclipse.org/downloads/download.php?file=/rt/eclipselink/releases/2.0.2/eclipselink-2.0.2.v20100323-r6872.zip

Extract the eclipselink.jar from the download jlib directory and include it in wildfly-8.1.0.Final\modules\system\layers\base\org\eclipse\persistence\main

edit wildfly-8.1.0.Final\modules\system\layers\base\org\eclipse\persistence\main\module.xml to add <resource-root path=”eclipselink.jar”/> so this file looks like
<module xmlns=”urn:jboss:module:1.3″ name=”org.eclipse.persistence”>
<resources>
<resource-root path=”jipijapa-eclipselink-1.0.1.Final.jar”/>
<resource-root path=”eclipselink.jar”/>

Set R path to x64 version, not i386
