Good Day all ,

I am having this problem since many days now , I was able to successfully deploy JPA2.0 appliaction on weblogic 10.3.3 , the application can run select queries using JPA. But when I try to run a create or update information on the same table I get below exception [code]

java.lang.ClassCastException: org.eclipse.persistence.jpa.PersistenceProvider cannot be cast to javax.persistence.spi.PersistenceProvider

[/code]

This is very strange because in my persistence.xml I have provided hibernate as JPA provider , the persistence unit defined is like below [code]

<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <!-- 

            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
             -->
            <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>


            <!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
            <property name="hibernate.hbm2ddl.auto" value="validate"/>
            <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
            <property name="hibernate.connection.charSet" value="UTF-8"/>
            <!-- Uncomment the following two properties for JBoss only -->
            <!-- property name="hibernate.validator.apply_to_ddl" value="false" /-->
            <!-- property name="hibernate.validator.autoregister_listeners" value="false" /-->
        </properties>
    </persistence-unit>

[/code] And I have also provided the package level preferences in my weblogic.xml , below is my weblogic.xml file. As you can see I have explicitly told weblogic to prefer web app packages still it’s trying to load org.eclipse.persistence.jpa.PersistenceProvider instead of a persistenceProvider from hibernate jar.Please help me out here I am stuck at this point [code]

You have to follow all that user1877955 said, and add this code, to avoid ClassCastException:

web.xml

<listener>
    <listener-class>com.bla.Init</listener-class>
</listener>

Init.java

package com.bla;

import javax.servlet.ServletContextEvent;

public class Initjavax.servlet.ServletContextListener {

    public void contextDestroyed(ServletContextEvent arg0) {

    }

    public void contextInitialized(ServletContextEvent arg0) {
        HibernatePersistenceProviderResolver.register();
    }
}

HibernatePersistenceProviderResolver.java

package com.bla;

import java.util.Collections;
import java.util.List;
import java.util.logging.Logger;

import javax.persistence.spi.PersistenceProvider;
import javax.persistence.spi.PersistenceProviderResolver;
import javax.persistence.spi.PersistenceProviderResolverHolder;

import org.hibernate.ejb.HibernatePersistence;

public class HibernatePersistenceProviderResolver implements PersistenceProviderResolver {
    private static final Logger LOGGER = Logger.getLogger(HibernatePersistenceProviderResolver.class.getName());

    private volatile PersistenceProvider persistenceProvider = new HibernatePersistence();

    public List<PersistenceProvider> getPersistenceProviders() {
        return Collections.singletonList(persistenceProvider);
    }

    public void clearCachedProviders() {
        persistenceProvider = new HibernatePersistence();
    }

    public static void register() {
        LOGGER.info("Registering HibernatePersistenceProviderResolver");
        PersistenceProviderResolverHolder.setPersistenceProviderResolver(new HibernatePersistenceProviderResolver());
    }
}
