Running on Wildly 8.2.0.Final. I get the following error when trying to generate a database schema from a script.
Caused by: javax.persistence.PersistenceException: Schema generation configuration indicated to include CREATE scripts, but no script was specified

Where the create script is located:
/src/main/resources/META-INF/create-script.sql
Thanks in advance!
The Wildfly persistence schema generator gui creates incorrect property names for the drop and create targets.
The correct property names are
<property name="javax.persistence.schema-generation.drop-script-source" value="META-INF/drop-script.sql"/>
<property name="javax.persistence.schema-generation.create-script-source" value="META-INF/create-script.sql"/>
change create-script to create-script-source and drop-script to drop-script-source

I'm looking to be able to enable or disable the eclipselink shared cache (second level cache) via the jboss-cli.
We generally have the shared-cache-mode set to DISABLE_SELECTIVE, but in certain deployments we would like to be able to disable it. It would be nice if we could do this via the jboss-cli and avoid editing our persistence.xml.
Anyone got any ideas or experience doing anything similar?
I've included our persistence.xml below. I'd be happy to provide anything else that might be helpful.

In case anyone else ever attempts to do this...
Edit your persistence.xml, setting the shared-cache-mode to a variable as follows:
<shared-cache-mode>${SHARED_CACHE_MODE}</shared-cache-mode>
Then you can add this variable into your standalone.xml by sending the following command to your jboss-cli (substituting DISABLE_SELECTIVE as appropriate):
/system-property=SHARED_CACHE_MODE:add(value=DISABLE_SELECTIVE)
The following article helped us a lot with this: http://www.mastertheboss.com/jboss-frameworks/hibernate-jpa/jpa-configuration/how-to-use-an-env-variable-in-your-persistencexml
I used logging in persistence.xml for EclipseLink JPA implementation, from
stackoverflow reference
but the parameters appears as ? how can i show them properly in my glassfish log output window.
The log level configuration is included in the definition of the persistence unit in the persistence.xml file, as follows:
The logging of SQL parameters can be enabled, or disabled through the following properties:
Disable:
Enable:
<property name="eclipselink.logging.level.sql" value="FINE"/>
<property name="eclipselink.logging.parameters" value="true"/>

Note: Setting eclipselink.logging.level to FINE is not sufficient (as of EclipseLink 2.4.0 - Juno), you have to set eclipselink.logging.level.sql to FINE.
This property will also control how parameters are logged in exceptions. By default parameters are only logged for log level < CONFIG.

You will need add in the configuration file persistence.xml the next entry
<property name="eclipselink.target-server" value="JBoss" />
Example complete:

this config can solved that error
I am setting up a minimal working example where I use EclipseLink in a Java EE (JSF) project. My example works perfectly with the following configuration and code:
persistence.xml
<persistence
version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"

<persistence-unit name="issat_PU_Local" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>pro.entity.Utilisateur</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/issat" />
<property name="javax.persistence.jdbc.user" value="java" />
<property name="javax.persistence.jdbc.password" value="JaVa" />
<property name="eclipselink.logging.level.sql" value="FINE" />
<property name="eclipselink.logging.parameters" value="true"/>
</properties>
</persistence-unit>
</persistence>
Since I don't want to use JTA I am using RESOURCE_LOCAL as transaction type and perfectly leaving with "manually" handling transaction inside my DAO.
I now want to use BoneCP connection pool with my example.
How should I precisely modify my persistence.xml to do that? I found many configuration examples in the internet using also Hibernate, but I want to stay with EclipseLink.
I couldn't do it with bonecp, but I could get a pool connection with C3PO.
I followed this link : http://javabeginnerstutorial.com/hibernate/connection-pooling-with-hibernate-4/
I copied the dependency and the properties but, instead of <property name="hibernate.c3p0.min_size">1</property> put the value in the tag like this<property name="hibernate.c3p0.min_size" value="1"/>, otherwise I got an error.
Finally mi persitence.xml look this way:
Im trying to use JPA to connect to a MS access DB using a JDBC:ODBC connection. Here is my Persistance.xml code :
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

<property name="toplink.jdbc.read-connections.min" value="1"/>
<property name="toplink.jdbc.write-connections.min" value="1"/>
</properties>
</persistence-unit>
</persistence>
But when i run the code, i get this error :
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named DSRJPA: The following providers:

Please throw me some light on this error.
Thanks in Advance.
Have you referenced your persistence unit in the class?
i.e.
EntityManagerFactory emf = Persistence.createEntityManagerFactory("DSRJPA");
