Configure JBOSS 7.1 to use application-managed entity manager as opposed to container-managed entity manager

I am trying to upgrade my application deployment from Jboss 6.4 to Jboss 7.1 and I've not been able to get past this error:
java.lang.IllegalArgumentException: WFLYWELD0037: Error injecting persistence unit into CDI managed bean. Can't find a persistence unit named 'entityManagerFactory' in deployment ***.war for injection point private javax.persistence.EntityManager com.***.persistenceManager"}}}}}}}}
I have entityManagerFactory defined as a bean in Spring's applicationContext.xml file as shown below:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="extiPU" />
<property name="dataSource" ref="dataSource" />
<property name="jtaDataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter">
<!--<property name="database" value="ORACLE" />-->
<property name="showSql" value="true" />
<property name="databasePlatform" value="org.eclipse.persistence.platform.database.OraclePlatform" />
<property name="generateDdl" value="true" />
</bean>
</property>
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" />
</property>
</bean>
and the content of my persistence.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<property name="eclipselink.logging.level" value="OFF" />
<!--

<property name="eclipselink.logging.level.sql" value="OFF" />

<property name="eclipselink.weaving" value="false" />
<property name="jboss.as.jpa.managed" value="false" />
</properties>
</persistence-unit>
In my persistence classes, I inject it by doing:
#PersistenceContext(unitName = "entityManagerFactory")
private EntityManager persistenceManager;
With all these done, I still cannot figure out why Jboss 7.1 does not allow the persistence manager to be application managed.
Thanks

Persistance.xml vs DispatcherServlet

I am using JPA 2.0, Hibernate 3 Annotation Version, the problem is that i am confusing in Persistence.xml & DispatcherServlet
My persistence.xml file contains:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

In my dispatcher servlet file I have following Beans:
<bean id="dataSource"

</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
Question is: why do we need to put all properties (DriverClassName, URL, UserName, Password) in both persistence.xml and in DataSource bean in DispatcherServlet?
I am learning and it is confusing me, please help.

Actually you have double configuration here.
You need either persistence.xml or bean definitions.

EntityManager and persist method not working properly

I'm in trouble here..
I'm new using Spring + Hibernate in a Java SE application...
I'm trying to instantiate the entityManager, but it's not working
I'm using the annotation #PersistenceUnit, like this:
#PersistenceUnit
public void setEmf(EntityManager emf) {
this.emf = emf;
}
And it works "fine", but it doesn't persist =/
When I change to
#PersistenceContext
public void setEmf(EntityManager emf) {
this.emf = emf;
}
It came out the following error:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'daoAbstract' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type '$Proxy10 implementing org.hibernate.ejb.HibernateEntityManagerFactory,org.springframework.orm.jpa.EntityManagerFactoryInfo' to required type 'javax.persistence.EntityManager' for property 'emf'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [$Proxy10 implementing org.hibernate.ejb.HibernateEntityManagerFactory,org.springframework.orm.jpa.EntityManagerFactoryInfo] to required type [javax.persistence.EntityManager] for property 'emf': no matching editors or conversion strategy found

This line is the problem:
<bean id="daoAbstract" class="com.planner.pvc.dao.DaoAbstract">
<property name="emf" ref="entityManagerFactory" />
</bean>
Instead of doing this, let Spring inject the emf field annotated with #PersistenceContext, this will happen if you have a <context:component-scan.../> or <context:annotation-config/> tags in your application context or just add the latter.

Thanks for any help :).

try the following:

<props>
...
<prop key="hibernate.hbm2ddl.auto">create-drop</prop>
</props>
</property>
<property name="dataSource" ref="dataSource" />
</bean>
This works for me.

I had exactly the same issue...
Commenting out property
<!--property name="generateDdl" value="true"--> in the JpaAdapter,
but setting
<property name="hibernate.hbm2ddl.auto" value="create"/> in persistence.xml
worked for me. I am using hsqldb.
I noticed in the logs that the mode was beign set to update no matter what I set in
persistence.xml.
The value in persistence.xml was actually picked up but never applied.
I am using Spring 3.0.6 and Hibernate 4

Can you try changing the generateDdl property to false on HibernateJpaVendorAdapter in your spring config file.
Seems to conflict with the hibernate hibernate.hbm2ddl.auto property
See https://jira.springframework.org/browse/SPR-6836 for more info.

In My hibernate-default.cfg.xml i used
<property name="hibernate.hbm2ddl.auto">update</property>
and it worked perfectly, so the config file was as follows
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="current_session_context_class">thread</property>
<!-- When an HQL statement declares a true/false, replace with the standard Y/N -->
<property name="hibernate.query.substitutions">true 'Y', false 'N'</property>
<!-- A useful property do debugging queries. Besure sure it is false or commented out when going PROD -->
<!-- <property name="hibernate.show_sql">true</property> -->
<!-- Format the printed out SQL generated by Hibernate -->
<property name="hibernate.format_sql">false</property>
<!-- If enabled, Hibernate will collect statistics useful for performance tuning - JMX -->
<property name="hibernate.generate_statistics">false</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<mapping class=....

sadly both solutions didn't work for me :(. "hibernate.hbm2ddl.auto=update" would be also ok, as it should create the tables if they're not present.
It seems that all property settings from the persistence.xml are recognized as username and database provider are set correctly. Sadly the tables aren't created at startup which causes my testcase to fail as the SELECT statement throws an error ...
As you can see, I've set the connection url to use a local file database, which allows me to review the database log after the test run. But the log file is still empty after the test run, even no error is written to it :(.

This worked for me
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.hsqldb.jdbcDriver" />
<property name="url" value="jdbc:hsqldb:mem://productDb" />
<property name="username" value="sa" />
<property name="password" value="" />
</bean>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="true" />
<property name="showSql" value="true" />
</bean>
</property>
If I change value to false like this<property name="generateDdl" value="false" /> then I get SqlExceptionHelper:144 - Table not found in statement

Maybe to late, but today I had the same problem when I was writing some tests for a legacy app.
I was using spring 2.5, hibernate3, and HSQL database.
To solve it I changed the database from HSQL to H2 and the datasource from org.springframework.jdbc.datasource.DriverManagerDataSource to org.apache.commons.dbcp.BasicDataSource.
The spring-context.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>

</persistence>
I hope it helps.

In my case, the tables were not been created because the objects annotated with #Table where not annotated as #Entity

Multiple Entity Manager issue in Spring when using more than one datasource

I have two entity managers in my applicationContext.xml which corresponds to two different databases. I can easily query database1 with entityManager1, but when I try to access database2 with entityManager2, I am not getting any results. I am using Spring+Hibernate+JPA.

<!-- MORE Action and DAO beans -->

This is my service layer code which works fine with enityManager1:
#Transactional
public class StatesDAO implements IStatesDAO {
private EntityManager em;
#PersistenceContext(unitName = "PU1")
public void setEntityManager(EntityManager em) {
this.em = em;
}
private EntityManager getEntityManager() {
return em;
}
#SuppressWarnings("unchecked")
public List<States> findAll() {
logger.info("finding all States instances");
try {
final String queryString = "select model from States model";
Query query = getEntityManager().createQuery(queryString);
return query.getResultList();
} catch (RuntimeException re) {
throw re;
}
}
}
My two persitence.xml files look like this:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
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">
<persistence-unit name="PU1" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.jpa.entity.States</class>
</persistence-unit>
</persistence>
and
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
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">
<persistence-unit name="PU2" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.jpa.other.entity.States</class>
</persistence-unit>
</persistence>
If I change my service layer (as shown below), I get no results. Basically the size of the list is zero:
#Transactional
public class StatesDAO implements IStatesDAO {
private EntityManager em;
#PersistenceContext(unitName = "PU2")
public void setEntityManager(EntityManager em) {
this.em = em;
}
private EntityManager getEntityManager() {
return em;
}
#SuppressWarnings("unchecked")
public List<com.jpa.other.entity.States> findAll() {
logger.info("finding all States instances");
try {
final String queryString = "select model from States model";
Query query = getEntityManager().createQuery(queryString);
return query.getResultList();
} catch (RuntimeException re) {
throw re;
}
}
}
So basically you can see is that I have two entities(States) with exactly same structure and in order to differentiate from each other I have put them into separate packages
According to my knowledge I am not doing anything crazy here but still it doesn't seem to be working. How is this problem caused and how can I solve this?
Follow-up: One thing I forgot to mention is that even though there are two different databases but the database server name is same. I don't know if this could be a useful information.So thought of sharing it.
This is the exception I am getting now:
16:24:44,732 INFO [STDOUT] Hibernate: select state0_.state as col_0_0_ from states state0_
16:24:44,753 WARN [JDBCExceptionReporter] SQL Warning: 36106, SQLState: 01I01

I've hit the same exact issue, but with multiple Hibernate session factories: 2 DBs with the same structure, I didn't want to have 2 identical sets of DAOs, etc. While my experience was with Hibernate, I suspect you could use the same solution: Spring's AbstractRoutingDataSource. It allows you to configure your app to determine at runtime which data source to use, based on a value set on the ThreadLocal. See http://blog.springsource.com/2007/01/23/dynamic-datasource-routing/ for an introduction. What ends up happening is that the dataSource ref in your factory will point not at a hard-coded dataSource bean, but at the AbstractRoutingDataSource. To set the toggle per-thread, use an #Aspect to determine which DB to hit.
