Spring3/JPA2 configuration problem

[John Eric Hamacher]

Hello:

I am getting:

Caused by: java.lang.IllegalArgumentException: No PersistenceProvider specified in EntityManagerFactory configuration, and chosen PersistenceUnitInfo does not specify a provider class name either
at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:250)
at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet(AbstractEntityManagerFactoryBean.java:310)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1514)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1452)
... 37 more

My app context contains:

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="jdbc.properties" /> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" p:driverClassName="${jdbc.driverClassName}" p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" /> <bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="loadTimeWeaver"> <bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/> </property> </bean>


My persistence file (located in META-INF under classes). hibernate.cfg.xml is located in WEB-INF but I specified WEB-INF as part of my classpath when I ran the program.

<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 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> <persistence-unit name="hibernate"> <properties> <property name="hibernate.ejb.cfgfile" value="hibernate.cfg.xml"/> </properties> </persistence-unit> </persistence>


My hibernate.cfg.xml:
<hibernate-configuration> <session-factory> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> </session-factory> </hibernate-configuration>


Thanks , Eric

Hi Eric,

There are the following issues in your configuration

1- You need to give a persistance provider in persistance.xml file. JPA2 has many implementations e.g. Hibernate, OpenJPA, EclipseLink. In your case
provide a persistance provider. You can specify the same in jpaVendor property. Specify the hibernate dialect as well.

2- Why you are specifying session factory for hibernate? JPA uses entity manager. You don't need to give session-factory configuration.

HTH,

Hi Eric,

Here is a sample integration project i created for you. My applicationContext.xml now looks like this

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </bean>

    <property name="entityManagerFactory" ref="entityManagerFactory"/>
  </bean>

  <tx:annotation-driven transaction-manager="txManager"/>

</beans>

My persistance.xml is empty and looks like this

<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 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
  <persistence-unit name="eshoppingcart" transaction-type="RESOURCE_LOCAL" >
   //No need to specify the provider as we already have specified JPA vendor in applicationContext.xml 
   <!-- <provider>org.hibernate.ejb.HibernatePersistence</provider> -->

     </persistence-unit>

</persistence>

I am writing a small blog article for Spring 3 and JPA2 will be completed by tomorrow. You can have a look at that also in a day or so at my blog.
HTH,

[John Eric Hamacher]

Thank you! Thank you for the responses! It is working now.
