Problems with JPA: locating peristence.xml

following, receiving, creating, exactly, figure

I can't seem to figure out exactly what to do here.  I keep receiving the following error when attempting to inject into my DAO class:

Context initialization failed

My app's structure is :

customer.war --gt; META-INF/MANIFEST.MF --gt; META-INF/persistence.xml    --gt; WEB-INF/classes --gt; WEB-INF/classes/data/DaoJpaImpl.class --gt; WEB-INF/classes/domain/Customer.class --gt; WEB-INF/lib --gt; WEB-INF/web.xml --gt; WEB-INF/applicationContext.xml

...

My persistence.xml file:

lt;?xml version=quot;1.0quot; encoding=quot;UTF-8quot;?gt;
lt;persistence version=quot;1.0quot; xmlns=quot;xml/ns/persistencequot; xmlns:xsi=quot;2001/XMLSchema-instancequot; xsi:schemaLocation=quot;xml/ns/persistence xml/ns/persistence/persistence_1_0.xsdquot;gt; lt;persistence-unit name=quot;AppPUquot; transaction-type=quot;JTAquot;gt; lt;jta-data-sourcegt;enrollmentlt;/jta-data-sourcegt; lt;classgt;domain.Customerlt;/classgt; lt;properties/gt; lt;/persistence-unitgt;
lt;/persistencegt;

My applicationContext file:

lt;?xml version=quot;1.0quot; encoding=quot;UTF-8quot;?gt;
lt;beans xmlns=quot;schema/beansquot; xmlns:xsi=quot;2001/XMLSchema-instancequot; xmlns:aop=quot;schema/aopquot; xmlns:tx=quot;schema/txquot; xsi:schemaLocation=quot; schema/beans schem...-beans-2.0.xsd schema/tx schem...ing-tx-2.0.xsd schema/aop schema/aop/spring-aop-2.0.xsdquot;gt;    lt;!-- JPA annotations bean post processor --gt; lt;bean class=quot;org..orm.jpa.support.Persist  enceAnnotationBeanPostProcessorquot;/gt;    lt;bean id=quot;Daoquot; class=quot;data.DaoJpaImplquot;/gt;
lt;/beansgt;

My DAO class:

public class DaoJpaImpl {    @Resource private UserTransaction utx;    @PersistenceUnit(unitName = quot;AppPUquot;) private EntityManagerFactory entityManagerFactory;       private EntityManager getEntityManager() {    return this.entityManagerFactory.createEntityManager(); }
...
...

And finally my Customer domain object:

@Entity
@Table(name = quot;CUSTOMERquot;)
@NamedQueries( {@NamedQuery(name = quot;Customer.findByCustomerIdquot;, query = quot;SELECT c FROM Customer c WHERE c.customerId = :customerIdquot;), @NamedQuery(name = quot;Customer.findByNamequot;, query = quot;SELECT c FROM Customer c WHERE c.name = :namequot;)})
public class Customer implements Serializable {
@Id @Column(name = quot;CUSTOMER_IDquot;, nullable = false) private Integer customerId;
@Column(name = quot;NAMEquot;) private String name;

...
...

*********************
I'm using Netbeans.  By default, it adds persistence.xml to classes/META-INF/persistence.xml.  I tried moving it to where it is now by modifying the build so it goes to META-INF/persistence.xml.  Same error though.

Where is Spring expecting this file to be?  The problem seems to be that Spring is looking somewhere else for this file.  I'm using Spring 2.0 RC4.

Any help would be appreciated.

Thanks,

Can someone verify for me that Spring should look in one of two places for persistence.xml (when using persistence.xml file for JPA configuration vs. specifying in a Spring config file):

WEB-INF/META-INF
-or-
WEB-INF/classes/META-INF

I know there have been some recent changes around how Spring looks for this file but I'm under the impression that those issues have been resolved with RC4.

Thanks,
Mike

If it's part of your war file then WEB-INF/classes/META-INF is the location to use.  Also, I don't see where you configure the EntityManagerFactory in your configuration file.  I think that's your problem, not the location of persistence.xml.
