Bean property 'entityManagerFactory' is not writable

[arungandhis]

Hello

I am getting the following error while deploying my application

"org.springframework.beans.NotWritablePropertyExce ption: Invalid property 'entityManagerFactory' of bean class [com.barclayswealth.minerva.dao.AccountDaoJPAImpl]: Bean property 'entityManagerFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?"

My persistence.xml
<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_1_0.xsd"

application context
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerE ntityManagerFactoryBean">
<property name="persistenceUnitName" value="MySpring"/>
<property name="dataSource" ref="dataSource"/>
</bean>


My JPADAOIMPL class

@Transactional
public class AccountDaoJPAImpl extends HibernateDaoSupport implements AccountDao {
private EntityManager em;

// Spring will inject this:
@PersistenceContext
public void setEntityManager(EntityManager em) {
this.em = em;
}

i am using the following jar files
persistence.jar, hibernate-entitymanager.jar, jboss-archive-browsing.jar, hibernate3.jar

The exception message is quite clear IMHO.

"org.springframework.beans.NotWritableProperty Exce ption: Invalid property 'entityManagerFactory' of bean class [com.barclayswealth.minerva.dao.AccountDaoJPAImpl]: Bean property 'entityManagerFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?"

Your bean doesn't have a setEntityManagerFactory method...

Please next time when posting code use [ code][/code ] tags!

Hello,

after the setEntityManagerFactory, i am getting the following error

ERROR [org.springframework.web.context.ContextLoader] Context initialization failed

Do you have the correct jpa-api in your classpath? Try the one supplied with Spring.

[arungandhis]

i am using persistence.jar file

is there any jpa-api.jar file ?

[arungandhis]

the application was having both
persistence.jar and ejb3-persistence.jar files

i have removed ejb3-persistence.jar file from class path

so now i have the following error

ERROR [org.springframework.web.context.ContextLoader] Context initialization failed

I have exactly the same problem youe have. Have anybody already find a solution for this issue?

kind regards

[Colin Yates]

If you review the javadoc for EntityManagerFactoryBean you will see it creates an EntityManagerFactory, not an EntityManager

Have you read http://static.springframework.org/sp...pa-setup-lemfb

[breskeby]

...but I think I read over some lines.

thanks a lot.

[Colin Yates]

no worries so is it working now?
