By specifying the eclipselink DDL generation properties you are using the native DDL generation mechanism and not the JPA 2.1 one.

JPA 2.1 allows you to generate without a DB connection, therefore, you must specify only the following JPA properties instead:

javax.persistence.schema-generation.scripts.action=""> javax.persistence.schema-generation.scripts.create-target=createDDL.sql
javax.persistence.schema-generation.scripts.drop-target=dropDDL.sql

And remove the eclipselink DDL properties:

eclipselink.create-ddl-jdbc-file-name=createDDL.sql

eclipselink.ddl-generation.output-mode=sql-script

eclipselink.ddl-generation=drop-and-create-tables

eclipselink.drop-ddl-jdbc-file-name=dropDDL.sql

Cheers,
Guy

Unsuccessfull.

Persistence.generateSchema() uses an EntityManager too, and that one wants to have a JDBC driver and connection...

Not sure, if using an in-memory DB is the appropriate solution, as I think there might be slight differences to a target-database "Oracle". What do you think?

cheers

Thanks, I'll give it a try.

Eventually, I'll incorporate it into https://github.com/lbreuss/eclipselink-ddlgeneration-maven-plugin/

cheers

In Eclipselink 2.5 try newly defined in JPA 2.1 Persistence.generateSchema(String persistenceUnitName, Map map)
including into the map ddl generation properties as well as eclipselink.target-database property.

Hi

is it possible to generate the DDLs without an actual DB connection?

If not, for what is the DB connection needed?
