begginers problem: persistence unit not found

[kumarunster]

Hi all,

i have a problem with hibernate-jpa integration with spring. I have searched the forum, but no explicit answer found for the problem

The problem is following:

Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: No persistence unit with name 'pmanager' found


I use the simpliest configuration for jpa, that is described in spring-reference.pdf: LocalEntityManagerFactoryBean

my applicationConfig.xml shows as

<bean id="entityManagerFactory"
	class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
		<property name="persistenceUnitName" value="pmanager" />		
</bean>

<bean id="transactionManager"
	class="org.springframework.orm.jpa.JpaTransactionManager">
	<property name="entityManagerFactory">
		<ref local="entityManagerFactory" />
	</property>
</bean>

<bean id="userDAO" class="test_spring.dao.jpa.UserDAOJPA">
	<property name="entityManagerFactory">
		<ref local="entityManagerFactory" />
	</property>
</bean>

persistence.xml have

<persistence-unit name="pmanager">
		
	<provider>org.hibernate.ejb.HibernatePersistence</provider>
		
	<properties>			
		<property name="hibernate.connection.driver_class"
			value="org.hsqldb.jdbcDriver" />
		<property name="hibernate.connection.url"
			value="jdbc:hsqldb:mem:appfuse" />
		<property name="hibernate.connection.username" value="sa" />
		<property name="hibernate.connection.password" value="" />
		<property name="hibernate.dialect"
			value="net.sf.hibernate.dialect.HSQLDialect" />
		<property name="hibernate.hbm2ddl.auto" value="create" />
			
	</properties>
</persistence-unit>

both, persistence.xml and applicationConfig.xml are in META-INF and in ClassPath

UserDAOJPA looks like

public class UserDAOJPA extends JpaDaoSupport implements UserDAO {

	public User getUser(Long userId) {
		return (User)getJpaTemplate().find(User.class, userId);
	}

	public List getUsers() {
		return getJpaTemplate().find("from User");
	}

	public void removeUser(Long userId) {
		Object user = getJpaTemplate().find(User.class, userId);
		getJpaTemplate().remove(user);
	}

	public void saveUser(User user) {
		getJpaTemplate().persist(user);		
	}

}

following libraries are in ClassPath:


antlr
asm
asm-attrs
sglib
commons-collections
commons-logging
commons-lang
dom4j
ejb3-persistence
hibernate3
hibernate-annotations
hibernate-commons-annotations
hibernate-entitymanager
hsqldb
jta
log4j
spring


have somebody any idea, how i can solve this problem?

many thanks and best regards,

Nikolai
