I try to configure JPA Hibernate with the following persistence.xml :
<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"
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="manager1" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<mapping-file>orm.xml</mapping-file>
<properties>
<property name="javax.persistence.jdbc.driver" value="x" />
<property name="javax.persistence.jdbc.url"
value="x;create=true" />
<property name="javax.persistence.jdbc.user" value="x" />
<property name="javax.persistence.jdbc.password" value="x" />
<property name="dialect" value="org.hibernate.dialect.DB2Dialect" />
<!-- EclipseLink should create the database schema automatically -->
<!-- <property name="eclipselink.ddl-generation" value="create-tables"
/> <property name="eclipselink.ddl-generation.output-mode" value="database"
/> -->
</properties>
</persistence-unit>
in the place "x" there are proper values, but I got:
log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named manager1
