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.
My persistence.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"

<property name="hibernate.show_sql" value="true" />
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup" />
</properties>
</persistence-unit>
</persistence>
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.
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-persistence-jpa</artifactId>
<version>6.5.0.Final</version>
<exclusions>
<exclusion>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
</exclusion>
</exclusions>
</dependency>
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:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'JPAKnowledgeServiceFactory' defined in class path resource [org/hasancansaral/jpaknowledgeservicesample/JPAKnowledgeServiceConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.kie.internal.runtime.StatefulKnowledgeSession]: Factory method 'JPAKnowledgeServiceFactory' threw exception; nested exception is java.lang.IllegalStateException: java.lang.reflect.InvocationTargetException

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" />

Null pointer expection creating EntityManagerFactory upgrading to Hibernate 5.1

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

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 am not sure how to set username/password. I am using the default settings only.
I managed to log into H2 console using credentials sa/sa.

I had also tried by setting password value as "sa" in these two files. But in that case I get a different error:

EDIT#2
Ok, I just replaced the JdbcUrl in activiti.cfg.xml from jdbc:h2:tcp://localhost/~/test to jdbc:h2:tcp://localhost/~/activiti
and tomcat is now starting fine, without errors. Not sure what happened.
I now log into H2 console without password just sa/"", works
I can now execute my BookOrderTest(the test case that uses H2 standalone DB) successfully BUT I still can't see a new queued task being created due to this test run at localhost/activiti-explorer web-app.
Any thoughts?
Thanks

We just faced the similar issue. The problem is that Activiti already comes with a h2*.jar or some version. And in our case server and client versions didn't match - it caused constant exceptions upon start
Deleve h2*.jar file from Activiti's lib folder.
Copy h2*.jar from your H2 server setup into lib.
Restart Tomcat (or whatever you have)

From your activit.cfg.xml
<property name="jdbcPassword" value="" />
From your db.properties
jdbc.password=
You said that you were able to connect using sa/sa but have empty password values in your files, it must be "sa"
EDIT #1
First of all, set your password "sa" in both activiti.cfg.xml and db.properties files.
Because you are trying basic stuff, it could be better to start with an in memory database: h2 in-memory database
Just set:
in your db.properties:
jdbc.url=jdbc:h2:mem:
in your activiti.cfg.xml:
<property name="jdbcUrl" value="jdbc:h2:mem:"/>
If you want to run H2 under mixed mode read this, that points to mixed mode, I think that's what you're trying to achieve.
Mixed mode configuration:
in your db.properties:
jdbc.url=jdbc:h2:/data/test;AUTO_SERVER=TRUE
in your activiti.cfg.xml:
<property name="jdbcUrl" value="jdbc:h2:/data/test;AUTO_SERVER=TRUE"/>

java.lang.ClassNotFoundException: org.apache.commons.dbcp2.datasources

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.

H2 database in Tomcat with Server Mode and Automatic Mixed Mode when using Activiti BPM with a Spring application context

When deploying the war file I am stuck on the following error:
INFO: Loading XML bean definitions from ServletContext resource [/WEB-INF/beans.xml]
Exception in thread "H2 TCP Server (tcp://127.0.1.1:56099) thread" java.lang.NoClassDefFoundError: org/h2/mvstore/db/TransactionStore$1
In the Maven dependencies/jars I am able to see the org.h2.mvstore.db.TransactionStore Class inside the file h2-1.4.178-sources.jar.
What I am trying to achieve is getting up and running a H2 database in Server Mode using the Automatic Mixed Mode. I would like to share this "H2 instance" among multiple war applications (i.e. the Activiti Explorer and my own Spring MVC Java application).
Should I "start" somehow this H2 instance that I am expecting running in the Tomcat server? I thought the answer is no after reading the documentation regarding the "Mixed Mode".
Is the following "Spring transaction stuff" (see below) getting Tomcat "blind" to the TransactionStore class provided in the Jar file with Maven?
Regarding the transactions in the Spring application context (needed when integrating an H2 database with Activiti using the dedicated classes defined under the "activiti-spring" package) I am currently not able to get them working. If I comment out the tx stuff (see below) then I am getting the following compiling error in the XML file in every place where a bean class is defined:
Build path is incomplete. Cannot find class file for org/aopalliance/intercept/MethodInvocation
The Spring application context is (see also I am using the Activiti integration with Spring):
