I have an ear file which contains only the basic configuration:



The properties I want to set external.
Inside the documentation:
https://docs.jboss.org/hibernate/orm/3. ... ogrammatic

I read, that I can define the path to hibernate.property with the parameter -Dproperty

Because I want to use different property files I start WildFly with this line for example:



The entityManager I get this way:
@PersistenceContext(unitName = "tdaSupply")
protected EntityManager entityManager;


In my program I can read the SystemProperty "property" with success.
But it seems, that hibernate can not find the property file. In my logfiie I can find this:

hibernate.cfg.Environment [ INFO] 20170412 14:39:38.769 ServerService Thread Pool -- 23 HHH000206: hibernate.properties not found

The entityManager is created with some standard properties which I have logged out with
Map<String, Object> properties = entityManager.getEntityManagerFactory().getProperties();
for(Map.Entry<String, Object> e : properties.entrySet())
{
logger.info("enMgr key = " + e.getKey() + ", val = " + e.getValue().toString());
}

There I can not find my properties from the external file.
It is not possible for me to use only one hibernate.properties file inside the ear, because I have to be flexible with every start of the WildFly and I can not manage two ear files. Reason is test with jenkins and all databases for example.

What is wrong?

It was a misunderstanding of the documentation.
-Dproperty=xxxx

doesn't mean -Dproperty=[path to hibernate.properties file]
it means: for example:
-Dhibernate.hbm2ddl.auto=create-drop

How can I use an external property file?
Is this possible with a hibernate.cfg.xml file?

If you want to use an external hibernate.cfg.xml file, you need to provide the hibernate.ejb.cfgfile configuration property.

Check out the project User Guide for more details about Hibernate configurations.
