I used Hibernate ORM with PostgresSql. And below is the persistence.xml for Hibernate ORM with PostgresSql.
<?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"> <persistence-unit name="store" transaction-type="JTA"> <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> <jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=store)</jta-data-source> <class>com.data.vo.Store</class> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/RMA" /> <property name="hibernate.connection.driver_class" value="org.postgresql.Driver" /> <property name="hibernate.connection.username" value="postgres" /> <property name="hibernate.connection.password" value="admin" /> </properties> </persistence-unit> </persistence> I have fine the persistence.xml in the MANIFEST using the following configuration statement to the maven-bundle-plugin: <Meta-Persistence>META-INF/persistence.xml</Meta-Persistence> I have placed my persistence.xml file in location src/main/resources/META-INF/persistence.xml. When I try to get the persistence object using Persistence.createEntityManagerFactory, I get the below exception Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named store I tried below options also. 1) Tried changing to MYSQL/PostgresSQL drivers for connecting to the DB 2) Made configuration changes in eclipse to remove the resource folder's excluded list from *.* to None. 3) Tried with Eclipselink also 4) Tried setting the ContextClassLoader to a classloader that can see the persistence provider as well as the database drivers. But none of the above option solved by issue. I need some help on this. -- View this message in context: http://karaf.922171.n3.nabble.com/Hibernate-ORM-with-PostgresSql-with-Karaf-4-1-0-tp4050580.html Sent from the Karaf - User mailing list archive at Nabble.com.
