#Autowired
private ApplicationContext applicationContext;
private JpaTransactionManager userTransactionManager;
private EntityTransaction userTx;
userTransactionManager = (JpaTransactionManager) applicationContext.getBean("provTransactionManager");
userTx = provTransactionManager.getEntityManagerFactory().createEntityManager().getTransaction();
userTx.begin();
boolean isUpdateSuccess = updateViaUserRepository(...);
if(!isUpdateSuccess) {
userTx.rollback();
} else {
userTx.commit();
}
My code is reaching userTx.rollback(); but actual database is not getting rolledback. Is there any mistake in my persisence or applicationContext configurations.
Edit: All my tables have engine as InnoDb

First thing to look for: what is the table type that you are using?
For example when it comes to MySQL, MyISAM tables do not support transactions, which means you have to use another table type (e.g. InnoDB).

Spring JPA Autoscan entities in jar file

I have two projects:
common and hrm
project common is a parent project(packaged as Jar) and hrm is a dependent project(packaged as war)
Dependency is specified through maven
Maven dependency is specified as:
<dependency>
<groupId>com.talentera</groupId>
<artifactId>common</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
My persistence XML in hrm project:

Please help me to make the entities available in common to be auto recognized in hrm project by spring-jpa
common is packaged as Jar and hrm is packaged as war.
Please let me know if I need to provide any more information here.

I had your same problem with a composite unit, I solved in this way:
you have to change
<jar-file>../../lib/common-0.0.1-SNAPSHOT.jar</jar-file>
with
<jar-file>WEB-INF/lib/common-0.0.1-SNAPSHOT.jar</jar-file>
ii should work

EclipseLink doesn't create tables

This is a comment that someone made to me about my XML so I am trying to see what he is talking about:
You should simplify your own life by using those hibernate. properties to define the DataSource in order to avoid a maintenance nightmare down the road by mixing them. It will help to avoid confusion like this. And don't hardcode the values that you have data properties for.*

Should be like this:
