Weblogic 10.3.3 trying to load org.eclipse.persistence.jpa.PersistenceProvider instead of configured Hibernate Provider

Question

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]

I have asked the same question on below two forums in search for quick help.

Answer 1

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());
    }
}

Answer 2

Below tip may also be helpfull for someone having the same problem

Please note that in order to run your JPA2.0 application on weblogic10.3.3 which is JPA1.0 compliant you will have to rename your persistence.xml to something like foo.xml and mentione the name of this xml file in your applicationContext.xml as (I am using Spring here )

<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
        <property value="classpath:META-INF/foo.xml" name="persistenceXmlLocation"/>
        <property name="persistenceUnitName" value="persistenceUnit"/>
        <property name="dataSource" ref="dataSource"/>
    </bean>

rename the persistenceUnit and dataSource according to the beans you have defined in your application

and you will have to define package exclusions in your weblogic.xml file as

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.1/weblogic-web-app.xsd"> 10.3.3

<wls:container-descriptor>
    <wls:index-directory-enabled>false</wls:index-directory-enabled>
    <!-- prefer-application-packages> <package-name>javax.persistence.spi.*</package-name> 
        </prefer-application-packages -->
    <wls:prefer-application-packages>
        <wls:package-name>antlr.*</wls:package-name>
        <wls:package-name>org.apache.commons.*</wls:package-name>
        <wls:package-name>org.apache.xmlbeans.*</wls:package-name>
        <wls:package-name>org.springframework.*</wls:package-name>
        <wls:package-name>org.hibernate.*</wls:package-name>

        <wls:package-name>org.hibernate.validator.*</wls:package-name>

        <wls:package-name>javax.persistence.*</wls:package-name>
        <wls:package-name>org.joda.*</wls:package-name>
    </wls:prefer-application-packages>
</wls:container-descriptor>

I invested few days to resolve the problem , and sharing the solution hoping it might benefit someone someday cheers.
