Hi all
I'm new in this task, so maybe my question could be very trivila.
Anyway, I'm trying to use JPA/Eclipselink with embedded HSQL.
All works very fine, I'm able to run tests, to create objects (tables) with attributes, to retrieve them, to execute queries and even to delete all objects.
But I don't see what I expected to see on disk.
My expectation was to see in folder also DB file(s); all I can see is a temp empty dir and 4 file (.lock, ,log, .properties and .script).
Here is my persistence.xml file
<?xml version="1.0" encoding="UTF-8" ?>
<persistence .....>
<!-- EclipseLink -->
<persistence-unit name="Test" transaction-type="RESOURCE_LOCAL">
<description>MIT</description>
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>org.test.jpa.JpaManagedObject</class>
<class>org.test.jpa.JpaManagedRelationship</class>
<properties>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:file:db/hsql/db"/>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value="*"/>
<property name="eclipselink.target-database" value="HSQL"/>
<property name="eclipselink.ddl-generation" value="create-tables"/>
<property name="eclipselink.create-ddl-jdbc-file-name" value="createDDL_ddlGeneration.jdbc"/>
<property name="eclipselink.drop-ddl-jdbc-file-name" value="dropDDL_ddlGeneration.jdbc"/>
<property name="eclipselink.ddl-generation.output-mode" value="both"/>
</properties>
</persistence-unit>
</persistence>
I'm using EclipseLink 2.5.2 and HSQL 2.3.2.
Is anyone able to help me?
Thanks in advance

You'll do better asking this in the EclipseLink forum--also an Eclipse
forum--rather than the newcomers' forum.
