Null pointer expection creating EntityManagerFactory upgrading to Hibernate 5.1

Null pointer expection creating EntityManagerFactory upgrading to Hibernate 5.1 - java

We create a EntityManagerFactory like this:
<bean id="dataSource"
class="org.apache.commons.dbcp2.BasicDataSource"
destroy-method="close"
p:driverClassName="${jdbc.driver}"
p:url="${jdbc.url}"
p:username="${jdbc.username}"
p:password="${jdbc.password}"
p:initialSize="${dbcp.initialSize}"
p:maxTotal="${dbcp.maxActive}"
p:maxIdle="${dbcp.maxIdle}"
p:minIdle="${dbcp.minIdle}"
p:maxWaitMillis="${dbcp.maxWait}"
p:validationQuery="${dbcp.validationQuery}"/>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="dataSource">
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.generate_statistics">${hibernate.generate_statistics}</prop>
</props>
</property>
</bean>
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="entityManagerFactory"
p:dataSource-ref="dataSource"/>
This works as expected in Hibernate 4. I upgraded to Hibernate 5.1.0 and started getting this exception:
UPDATE: This is not a Hibernate 5 specific issue. This actually happens just upgrading from hiberate 4.2.5.Final to 4.3.5.Final

Update2: Here is the persistence.xml as requested in comments:

The issue is clearly a null pointer exception but what is null? The error doesn't give any detail as to what is causing the null pointer exception. Any ideas on what is going on would be greatly appreciated.

I don't know why above code is not working. Any help would be much appreciated. Dependency should work properly.
Where is the problem? Why Autowire is not working in controller. Is it problem in Application.xml file?

Please check your standalone.xml in your server configuration.
Add this mapping in extensions tag
<extension module="org.jboss.as.jpa"/>
And this mapping in profile tag
<subsystem xmlns="urn:jboss:domain:jpa:1.1">

java.lang.NullPointerException when creating a StatefulKnowledgeSession with JPAKnowledgeService

I am trying to get JPAKnowledgeService work with my Spring Boot application. For this I have followed the instructions from here.

I haven't defined transaction boundaries and I had to exclude hibernate-ja-2.0-api from drools-persistence-jpa to use 2.1 that is provided by Spring itself.

Upon calling newStatefulKnowledgeSession like this:
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" ) );
env.set( EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager() );
KieSession kSession = JPAKnowledgeService.newStatefulKnowledgeSession(kieBase, null, env);
I am getting the following error:

I also have a sample repo to recreate this error that can be found here. Any help is greatly appreciated. Thanks!

you need to use jndi.properties file in the root of your class path to point java to use bitrnix as JNDI provider so it can bind transaction manager into JNDI so then JtaTransactionManager can look it up
create new file: src/main/resources/jndi.properties with following content:
java.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFactory

It seems that you are using JTA transactions, try with this property:
<property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.NoJtaPlatform" />

HIbernate 4 Spring 4.2.2: "Could not obtain transaction-synchronized Session for current thread" while injecting property

I've got a fairly complex situation and tried every resource I could find; I already asked the question here but I have quite a lot of new information so I'll post the question again (rephrased now).
So, I've got a
extract-ws-context.xml
which contains:
<import resource="classpath:weblogic-env-context.xml"/>
<import resource="classpath:dao-context.xml"/>
<import resource="classpath:business-context.xml"/>
<import resource="classpath:extract-ws-context.xml"/>
<import resource="classpath*:/jobs/extract-unmarsh-context.xml"/>
<import resource="classpath*:/jobs/batch-context.xml"/>
<import resource="classpath*:/jobs/extract-job.xml"/>
<import resource="classpath*:/ws-context.xml"/>
dao-context.xml contains (among bean definitions):
<!-- Enable the configuration of transactional behavior based on annotations -->
<bean id="transactionManager" name="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!-- Enable the configuration of transactional behavior based on annotations -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="datasource"/>
<property name="packagesToScan" value="be.fgov.just.cjr.model"/>
<property name="hibernateProperties">
<props>
<prop key="hibernate.bytecode.use_reflection_optimizer">true</prop>
<prop key="hibernate.dialect">be.fgov.just.cjr.oracle.OracleDialectWithXmlTypeSupport</prop>
<prop key="hibernate.search.autoregister_listeners">false</prop>
<prop key="hibernate.transaction.factory_class">

<prop key="hibernate.use_sql_comments">true</prop>

<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
</bean>
One of the beans there is:
<bean id="ListOfValuesDao" class="be.fgov.just.cjr.dao.core.ListOfValuesDaoImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
Another one is:
<bean id="GenericDao" class="be.fgov.just.cjr.dao.GenericDaoImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
Now, this is part of the GenericDaoImpl:
#Transactional
public class GenericDaoImpl implements GenericDao {
private SessionFactory sessionFactory;
#Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
#Override
public Session getSession() {
try {
return sessionFactory.getCurrentSession();
}catch (HibernateException h){
log.error("HibernateException",h);
h.printStackTrace();//for debugging purposes
}
return null;
}
The strange thing is:
for some calls to getSession() a session is returned, for the call I'm currently working on, getSession() throws a "org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread"
(with following stack trace:)

to say it short:
this exception occurs when the extractWSServiceEndpoint is created:

which is defined in the extract-ws.xml:
<context:component-scan base-package="be.fgov.just.cjr.ws.extract"/>
<tx:annotation-driven transaction-manager="transactionManager"/>
and which class definition starts as thus:
package be.fgov.just.cjr.ws.extract.service;
//imports
#Endpoint
public class ExtractWSServiceEndpoint {
#Autowired
private ExtractWSService extractWSService;
with and the definition of ExtractWSService starts like this:
package be.fgov.just.cjr.ws.extract.service;
//imports
#Slf4j
#Getter
#Setter
#Transactional
#Service
public class ExtractWSServiceImpl implements ExtractWSService {
the extract-ws.xml is imported in the "extract-ws-context.xml" (which is imported in extract-ws-context.xml as shown above)
when this bean is created this code is executed:
public void setLovDao(ListOfValuesDao lovDao) {
toSend = lovDao.getNotificationStatus(TO_SEND);
error = lovDao.getNotificationStatus(ERROR);
erased = lovDao.getNotificationStatus(ERASED);
sent = lovDao.getNotificationStatus(SENT);
on_hold = lovDao.getNotificationStatus(ON_HOLD);
}
and the
toSend = lovDao.getNotificationStatus(TO_SEND);
calls end up calling the
getSession()
displayed at the top of this post;
I guess my question boils down to this:
1) how do I get a Session while Spring is creating beans/autowiring/injecting
properties
2) if this is no longer possible, why was it possible before and:
3) how do I get data from hibernate to initialize my beans?
thanks for reading/pointers/help,

I have tried to clean and redeploy several times but the error remains same.
In the starting of the error, a class is specified as not found, and this path keeps on changing on every new deployment. I was successfully able to work on this project till today morning and have found this issue after restarting my eclipse. I have not made any changes in any of the configurations which I was using, so I strongly believe that this is not related to any of the XML files associated with the project.
A part of my root-context.xml file is:

I have added the necessary jars for the project but still i get the following mentioned exception. I am confused whether this is because of spring-mvc or commons.dbcp2. Can someone help me out to solve with explanation

According to the maven site commons-dbcp2-2.1.jar depends on:
commons-logging » commons-logging 1.2
junit » junit 4.11
org.apache.commons » commons-pool2 2.3
org.apache.geronimo.modules » geronimo-transaction 1.2-beta
org.apache.geronimo.specs » geronimo-jta_1.1_spec 1.1.1
tomcat » naming-common 5.0.28
tomcat » naming-java
See: DBCP2-Maven
So you also need this jars. The class you need for this exception in particular is in commons-pool2, I think.
If you start using Maven or Gradle you will avoid issues with dependencies like this. Here is a good tutorial for Spring with Maven: The tutorial

For me, the issue was that my local m2 cache of the JAR file was corrupt. After I deleted it, Maven said it could not download 2.1.1. I switched to 2.5.0 and the app loaded successfully.
