when run application in intellij idea and deploy on local wildfly server. wildfly dont use this persistence-unit and use default data source.
and crud actions not persist on mysql db and that actions persist on default datasource that is h2 database.

I am not able to access the postgresql db properties, which are in small letters. I would like to access the properties using camelCase. Please suggest me the required configuration .
for configure postgreSQL using JPA you can use this persistence.xml
For that you have to create one folder called "META-INF" in your project. and in that folder you have to store this file.
persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"

Or using hibernate.cfg.xml
(Here no need to create "META-INF folder")

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.

I've tried several ways to change the FlushMode to the complete application.
Is this right or is there another way to do it?
I don't want to do this pragmmatically.
This is was what i find as property but it isn't work.
<persistence 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

version="2.0">
<persistence-unit name="myPU">
<properties>
...
<property name="hibernate.connection.autocommit" value="false"/>
<!-- Also tried this: -->
<property name="org.hibernate.FlushMode" value="commit"/>
...
</properties>
</persistence-unit>
</persistence>
Update:
I've created the class as described in the link by zxcf, but i can't figure out how to add this construct in my persistence.xml.
<property name="jpaDialect">
<bean class="test.jpa.vendor.HibernateJpaDialect">
<property name="flushMode" value="MANUAL"/>
</bean>
</property>
Try this
<property name="org.hibernate.flushMode" value="COMMIT"/>
Testing this on a standalone program I can see the changed value of underlying Hibernate Session / EntityManager from AUTO to COMMIT
Here is my persistence.xml

And here is how I test it
EntityManagerFactory emf = Persistence.createEntityManagerFactory("JPATest");
EntityManager em = emf.createEntityManager();
Session session = em.unwrap(Session.class);
System.out.println("Underlying Hibernate session flushmode ####### "+session.getFlushMode());
System.out.println("EntityManager flushmode ####### "+em.getFlushMode());
This gives me
Underlying Hibernate session flushmode ####### COMMIT
EntityManager flushmode ####### COMMIT
If I omit the property in presistence.xml, I get this
Underlying Hibernate session flushmode ####### AUTO
EntityManager flushmode ####### AUTO
Ancient Hibernate 3.2.4.sp1 from JBoss 4.2.3.GA supports only the following notation:
<property name="flush-mode" value="commit"/>
Earlier in my project I was using a combination of Hibernate 3.3.2, openJPA 2.1.1 to connect to the database and retrieve the information from table. Now I want to remove Hibernate and use openJPA for doing connection and retrieving the information.
My earlier configuration of persistence.xml was
<?xml version="1.0" encoding="UTF-8"?>
<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 persistence_2_0.xsd">

Now I want to move to openJPA 2.1.1 and for that my persistence.xml file is
<?xml version="1.0" encoding="UTF-8"?>
<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">

<property name="openjpa.DataCache" value="true"/>
<property name="openjpa.QueryCache" value="true"/>
</properties>
</persistence-unit>
</persistence>
My question is what are the replacement property for following hibernate property in openJPA
<property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="hibernate.cache.provider_class" value="org.hibernate.cache.OSCacheProvider"/>
<property name="hibernate.cache.use_second_level_cache" value="true"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="true"/>
<property name="hibernate.c3p0.min_size" value="5"/>
<property name="hibernate.c3p0.max_size" value="20"/>
<property name="hibernate.c3p0.timeout" value="1800"/>
<property name="hibernate.c3p0.max_statements" value="50"/>
<property name="hibernate.c3p0.idle_test_period" value="1800"/>
After many trial and error I have found some replacement parameters. My present persistence.xml file looks like
persistence.xml:
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<properties>
<property name="openjpa.ConnectionURL" value="jdbc:mysql://xx.xx.xx.xx:3306/dbname"/>
<property name="openjpa.ConnectionDriverName" value="com.mysql.jdbc.Driver"/>
<property name="openjpa.ConnectionUserName" value="xxx"/>
<property name="openjpa.ConnectionPassword" value="xxx"/>
<property name="openjpa.DynamicEnhancementAgent" value="true"/>
<property name="openjpa.RuntimeUnenhancedClasses" value="supported"/>
<property name="openjpa.Log" value="SQL=TRACE"/>
<property name="openjpa.ConnectionFactoryProperties" value="PrettyPrint=true, PrettyPrintLineLength=72, PrintParameters=true, MaxActive=10, MaxIdle=5, MinIdle=2, MaxWait=60000"/>
</properties>
For connection pooling information check and for all OpenJPA Properties check
Hope this helps
And created a new user, I have granted it select/update delete rights on specific tables as required.
Will this be enough to use persistence, or will jboss need admin rights as well ?
No, it shouldn't need admin rights.
Easiest answer - try it and see.
No, no need to assign admin rights. It will enough by using persistence.xml
please add following in your persistence.xml
<persistence-unit name="abc" transaction-type="JTA"> and
<jta-data-source>java:jboss/datasources/data_source_name</jta-data-source>
persistence.xml should like this:
<?xml version="1.0" encoding="UTF-8"?>
<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/persistence_2_0.xsd">
<persistence-unit name="abc" transaction-type="JTA">
<jta-data-source>java:jboss/datasources/data_source_name</jta-data-source>

<!-- Map entity classes -->
<class> com.packege.classname </class>
<properties>
<!-- Properties for Hibernate -->
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />

<property name="hibernate.show_sql" value="true" />
</properties>

</persistence>
and provide the persistence unit name to createEntityManagerFactory method in Hibernate util class.
Persistence.createEntityManagerFactory("abc");
