Hello Everyone

Since quite some time I am trying to configure my little app to use
EclipseLink 2.0 with JPA 2 and configure it via Spring 3.

I am using the latest Spring release (3.0.2) and I am running into all
kinds of errors when the application is started.

My persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<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
persistence_2_0.xsd"
version="1.0">
<!-- version="2.0"> -->

<persistence-unit name="itea" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider >
<class>de.eye4eye.itea.model.User</class>
<class>de.eye4eye.itea.model.EntityBase</class>
<properties>
<property name="javax.persistence.jdbc.url"
value="jdbc:mysql://localhost:3306/itea" />
<property name="javax.persistence.jdbc.driver"
value="com.mysql.jdbc.Driver" />
<property name="javax.persistence.jdbc.username" value="itea" />
<property name="javax.persistence.jdbc.password" value="4711" />
<property name="eclipselink.target-database" value="MySQL" />
<property name="eclipselink.ddl-generation" value="create-tables"/>
<property name="eclipselink.logging.level" value="INFO" />
</properties>
</persistence-unit>

My latest attempt in the spring-configuration looks like this

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

I am getting this error and I couldnt find any resources on it

org.springframework.beans.factory.BeanCreationException: Error creating
bean with name 'entityManagerFactory' defined in class path resource

Sorry, that I cannot more precise. I am a beginner in Jpa and Spring. If
someone has a working example it would be awesome

Thanks in advance.

Well, I got it running, but dont ask me what exactly I am doing here ( I
was just putting together some snippets I found here and there). If I am
running JPA2 now...I dont know :D

This is my bean-configuration

<bean id="entityManagerFactory"

class=" org.springframework.orm.jpa.LocalContainerEntityManagerFacto ryBean ">
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="itea" />
<property name="jpaDialect" ref="jpaDialect" />
<property name="jpaVendorAdapter">
<bean
class=" org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapt er ">
</bean>
</property>
<property name="loadTimeWeaver">
<bean

class=" org.springframework.instrument.classloading.SimpleLoadTimeWe aver " />
</property>
</bean>

<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource ">
<property name="username" value="db" />
<property name="password" value="xxxx" />
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost/itea" />
</bean>

<bean id="jpaDialect"
class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect " />

<bean
class=" org.springframework.orm.jpa.support.PersistenceAnnotationBea nPostProcessor "/>


BUT I AM A BIT CONFUSED BY THIS: why do I need to specify the
database-information for Spring again when I already have within the
persistence.xml?

Please enlighten me :)

When using Spring you should define a datasource which will be passed to
EclipseLink when it creates the EntityManagerFactory. And when using a
datasource you don't provide database login properties.

Take a look at the Spring JPA PetClinic for a full example.
