How to configure wildfly to use EclipseLink?

Question

i have installed wildfly 8.1 and because i have already a project configured to use EclipseLink, i have tried to configure wildfly to use it.

However, it always gives the same error :

at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:166) [wildfly-server-8.1.0.Final.jar:8.1.0.Final]

I have followed the instructions of the official documentation, but nothing changed. I have added the eclipseLink's jar to "modules\system\layers\base\org\eclipse\persistence\main" and the module.xml :

<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"/>
    </resources>

    <dependencies>
        <module name="asm.asm"/>
        <module name="javax.api"/>
        <module name="javax.annotation.api"/>
        <module name="javax.enterprise.api"/>
        <module name="javax.persistence.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.validation.api"/>
        <module name="javax.xml.bind.api"/>
        <module name="org.antlr"/>
        <module name="org.apache.commons.collections"/>
        <module name="org.dom4j"/>
        <module name="org.javassist"/>
        <module name="org.jboss.as.jpa.spi"/>
        <module name="org.jboss.logging"/>
        <module name="org.jboss.vfs"/>
    </dependencies>
</module>

Do you know what is the problem ?

Edit : My persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="AppPu">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <jta-data-source>java:/H2Ds</jta-data-source>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
    </persistence-unit>
</persistence>

Answer 1

New lines in provider section of persistence.xml won't work (how could it help?). Wildfly hasn't got provided eclipseLink implementation in libs. To fix this follow this steps:

1. Download eclipselink.jar (or copy from your maven repo)
2. Copy it to destination : ...Wildfly\modules\system\layers\base\org\eclipse\persistence\main
3. Edit module.xml (same path). Add section <resource-root path="eclipselink.jar"><filter><exclude path="javax/**" /></filter></resource-root>

After server restart everything should work.

Answer 2

Finally I solved the problem!

in fact, I have a composite unit, all persistence.xml are correct, but the persistence.xml which declared the composite unit was a bad statement of the provider:

<provider>
   org.eclipse.persistence.jpa.PersistenceProvider
</provider>

replaced by :

<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

and now work fine.
