No Persistence provider with Maven build java, hibernate, getting, target

amy

I have a sample application that works fine as a plain old java project in Eclipse but when I set up a Maven project for it, I'm getting a quot;No Persistence provider for EntityManager named craigPersistenceUnitquot;. My thought was that it was unable to find the META-INF/persistencce.xml file so I print out the classpath in the test. That prints out, among other things:

/C:/dev/eclipse/hibernate/SpringHibernateMaven/target/test-classes/
/C:/dev/eclipse/hibernate/SpringHibernateMaven/target/classes/

Just to be safe, I included those files in both the test and main directories and it does get copied over. Codeirectory of C:\dev\eclipse\hibernate\SpringHibernateMaven\target\classes\META-INF

01/14/2011  04:14 PM             1,150 persistence.xml   1 File(s)          1,150 bytes
Directory of C:\dev\eclipse\hibernate\SpringHibernateMaven\target\test-classes\META-INF

01/14/2011  04:23 PM             1,152 persistence.xml   1 File(s)          1,152 bytes
Just to close the loop here is my Spring config:Code:
lt;?xml version=quot;1.0quot; encoding=quot;UTF-8quot; standalone=quot;noquot;?gt;
lt;beans xmlns=quot;schema/beansquot;      xmlns:tx=quot;schema/txquot;      xmlns:context=quot;schema/contextquot;      xmlns:xsi=quot;2001/XMLSchema-instancequot;      xsi:schemaLocation=quot;schema/beans               schema/beans/spring-beans-3.0.xsd               schema/context               schema/context/spring-context-3.0.xsd               schema/tx               schema/tx/spring-tx-3.0.xsdquot;gt;

lt;context:component-scan base-package=quot;craig.testquot; /gt;

lt;context:property-placeholder location=quot;classpath*:spring-config/*.propertiesquot; /gt;

lt;bean id=quot;entityManagerFactoryquot;
class=quot;org..orm.jpa.LocalEntityManagerFactoryBeanquot;gt;
lt;property name=quot;persistenceUnitNamequot; value=quot;craigPersistenceUnitquot; /gt;
lt;/beangt;

lt;bean id=quot;transactionManagerquot; class=quot;org..orm.jpa.JpaTransactionManagerquot;gt;
lt;property name=quot;entityManagerFactoryquot; ref=quot;entityManagerFactoryquot; /gt;
lt;/beangt;
   lt;tx:annotation-driven transaction-manager=quot;transactionManagerquot;/gt;

lt;/beansgt;
And here is my persistence.xml:Code:
lt;?xml version=quot;1.0quot; encoding=quot;UTF-8quot; standalone=quot;noquot;?gt;
lt;persistence xmlns=quot;xml/ns/persistencequot;
xmlns:xsi=quot;2001/XMLSchema-instancequot;
xsi:schemaLocation=quot;xml/ns/persistence xml/ns/persistence/persistence_2_0.xsdquot;
version=quot;2.0quot;gt;

lt;persistence-unit name=quot;craigPersistenceUnitquot;
transaction-type=quot;RESOURCE_LOCALquot;gt;
lt;propertiesgt;
lt;property name=quot;hibernate.connection.driver_classquot; value=quot;oracle.jdbc.driver.OracleDriverquot; /gt;
lt;property name=quot;hibernate.connection.uclquot; value=quot;jdbcracle:thinlocalhost:1521:XEquot; /gt;
lt;property name=quot;hibernate.dialectquot; value=quot;org.hibernate.dialect.OracleDialectquot; /gt;
lt;property name=quot;hibernate.connection.usernamequot; value=quot;findlawquot; /gt;
lt;property name=quot;hibernate.connection.passwordquot; value=quot;passwordquot; /gt;
lt;property name=quot;hibernate.default_schemaquot; value=quot;findlawquot; /gt;
lt;property name=quot;hibernate.show_sqlquot; value=quot;truequot; /gt;
lt;property name=quot;hibernate.current_session_context_classquot; value=quot;threadquot; /gt;
lt;property name=quot;hibernate.hbm2ddl.autoquot; value=quot;updatequot; /gt;
lt;/propertiesgt;
lt;/persistence-unitgt;

lt;/persistencegt;
Any thoughts on what is going on? Any suggestions for troubleshooting? Thanks.

You get this error when you run through maven? If so, then do you do any resource exclusions in maven-compiler-plugin or maven-war-plugin?

Sorry, I should have been more specific. I get it when I run a unit test. I've included the trace from the error below:

Few things to verify,

1. Is your persistence.xml in a place that is accessible to the unit test

2. Did you try adding lt;providergt; for the persistence-unitCode:
lt;providergt;org.hibernate.ejb.HibernatePersistencelt;/providergt;
I'm not that sure if the second problem can cause that exception. But just to be sure

I rearranged the config to use a datasource instead and the error was more clear at that point. I had forgotten the Oracle dependency.
