Wildfly 10.1.0

eclipselink.md

Criar módulo

1. Adicionar eclipselink-2.6.4.jar no diretório modules/system/layers/base/org/eclipse/persistence/main no wildfly
2. Referenciar o jar no arquivo module.xml, adicionando um novo resource-root abaixo do existente

  <resource-root path="eclipselink.jar">           
    <filter>
        <exclude path="javax/**" />
    </filter>
  </resource-root>

3. Adicionar a seguinte dependência dentro do elemento <dependencies> do module.xml

<module name="javax.ws.rs.api"/> 

4. Adicionar a seguinte propriedade no standalone.xml dentro de <system-properties>, se não existir o elemento system-properties, criá-lo abaixo de </extensions>

<system-properties>
    <property name="eclipselink.archive.factory" value="org.jipijapa.eclipselink.JBossArchiveFactoryImpl"/>
</system-properties>

Configurar unidade de persistencia

A unidade de persistência deve ser criada com o provider do eclipselink:

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

oracle.md

Adicionar módulo do oracle

1. Criar o diretório modules\system\layers\base\com\oracle\ojdbc6\main
2. Adicionar ojdbc6.jar no diretório acima
3. Adicionar o arquivo module.xml ao diretório acima, com os seguinte conteúdo:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.oracle.ojdbc6">
  <resources>
    <resource-root path="ojdbc6.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
	<module name="javax.transaction.api"/>
  </dependencies>
</module>

Adicionar driver no standalone.xml

Adicionar o seguinte driver dentro do elemento <drivers> do standalone.xml

<driver name="oracle" module="com.oracle.ojdbc6">
   <xa-datasource-class>oracle.jdbc.OracleDriver</xa-datasource-class>
</driver>

Using EclipseLink
You need to copy the EclipseLink jar (e.g. eclipselink-2.6.0.jar or eclipselink.jar as in the example below) into the WildFly modules/system/layers/base/org/eclipse/persistence/main folder and update modules/system/layers/base/org/eclipse/persistence/main/module.xml to include the EclipseLink jar (take care to use the jar name that you copied in).  If you happen to leave the EclipseLink version number in the jar name, the module.xml should reflect that.

<module xmlns="urn:jboss:module:1.1" name="org.eclipse.persistence">
    <resources>
        <resource-root path="jipijapa-eclipselink-10.0.0.Final.jar"/>
        <resource-root path="eclipselink.jar">           
           <filter>
              <exclude path="javax/**" />
           </filter>
        </resource-root>
    </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="javax.ws.rs.api"/>
        <module name="org.antlr"/>
        <module name="org.apache.commons.collections"/>
        <module name="org.dom4j"/>
        <module name="org.jboss.as.jpa.spi"/>
        <module name="org.jboss.logging"/>
        <module name="org.jboss.vfs"/>
    </dependencies>
</module>
As a workaround for  issueid=414974, set (WildFly) system property "eclipselink.archive.factory" to value "org.jipijapa.eclipselink.JBossArchiveFactoryImpl" via jboss-cli.sh command (WildFly server needs to be running when this command is issued):

jboss-cli.sh --connect '/system-property=eclipselink.archive.factory:add(value=org.jipijapa.eclipselink.JBossArchiveFactoryImpl)'
.  The following shows what the standalone.xml (or your WildFly configuration you are using) file might look like after updating the system properties:

<system-properties>
   ...
   <property name="eclipselink.archive.factory" value="org.jipijapa.eclipselink.JBossArchiveFactoryImpl"/>
</system-properties>
You should then be able to deploy applications with persistence.xml that include;

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