Makkus B. commented on OPENJPA-2886:
------------------------------------
Yesterday I also tested this approach with ecliselink resulting in the
identical behavior. So I suspect that my way is not really the correct way to
set up a persistance unit at runitme...
> javax.persistence.schema-generation.database.action setting seems to be
> ignored when using Persistence.createEntityManagerFactory()

> Key: OPENJPA-2886
> URL: https://issues.apache.org/jira/browse/OPENJPA-2886
> Project: OpenJPA
> Issue Type: Question
> Components: jpa
> Affects Versions: 3.1.2
> Environment: TomEE 8.0.6 (and 8.0.9-SNAPSHOT), Netbeans 12.5, MS
> Windows 10
> Reporter: Makkus B.
> Priority: Major
>
> As I'm very new to OpenJPA I'm not quite sure, if this the follwing is an
> OpenJPA issue but I obeserve that:
> When creating a persistence unit via persistence.xml (Tomee 8) openJPA
> creates missing entity tables according to the
> javax.persistence.schema-generation.database.action property. However, Im
> currently testing a 'runtime' datasource configuration like this:
>
> {code:java}
> Properties props = new Properties();
> props.put("javax.persistence.jtaDataSource", "jdbc/dynamicDb");
> props.put("openjpa.ConnectionDriverName", "org.mariadb.jdbc.Driver");
> props.put("openjpa.ConnectionURL",
> "jdbc:mariadb://localhost:3306/test");
> props.put("javax.persistence.schema-generation.database.action",
> "create");
> EntityManagerFactory factory =
> Persistence.createEntityManagerFactory("test-unit3", props);
> return factory.createEntityManager();{code}
> When caling persist() on the created EntityManager I get a rollback excpetion
> due to missing database tables although
> javax.persistence.schema-generation.database.action is given as "create".
> When debugging I can see, that the
> javax.persistence.schema-generation.database.action property value is 0.
> Two questions:
> a) It what I am doing a legal way to create an entity manager at all?
> b) Why are no tables created in this case ( but are when using the
> persitence.xml)?
