Database creation not working in eclipselink with glassfish 4 and postgress [message #1701140]

Helo all,

I want to create the database based on Entities. Configuration:

Glassfish: GlassFish Server Open Source Edition 4.1 (build 13)
Eclipselink: Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd (delivered with glassfish)
Database: PostgreSQL Version: 9.4.2
Driver: PostgreSQL Native Driver Version: PostgreSQL 9.4 JDBC4.1 (build 1201)

From the moment eclipselink starts creating the database I see the following statements in the logs after putting a lot of log parameters on finest:

SELECT ID FROM table_name WHERE ID <> ID
SELECT 1

This is repeated 4-5 times. The first query gives the following obvious postgres error:

org.postgresql.util.PSQLException: ERROR: relation "table_name" does not exist Position: 16

As a result a following queries give the following error:

org.postgresql.util.PSQLException: ERROR: current transaction is aborted, commands ignored until end of transaction block

After this eclipselink continues creating the tables:

CREATE TABLE table_name (ID BIGINT NOT NULL, PRIMARY KEY (ID))

But produces the same error.

For some reason creating the database happens in a transaction. I found the source code responsible, but I can't find out how the transaction is started. I can give more detailed information, but maybe somebody can already help now.

Best regards.

Have you tried setting the eclipselink.target-database property to PostgreSQL or org.eclipse.persistence.platform.database.PostgreSQLPlatform?

Please also share your persistence.xml file if the above does not resolve the issue.

By setting this I get the same error message, but in a slightly different form.

This is the persistence.xml:

The http are connected in my file. I just can't post links...
