H2 & DBUnit setup - dbunit

Question

I want to initialize an H2 in memory database using DBUnit for unit tests with a schema. I based my code on https://www.baeldung.com/java-dbunit and tried to amend it to use a table with a schema. Using the H2 console, I can see that the schema has been created and that the table has been created in the schema, but the table is empty and the assertion fails.
package de.kn.info.accountplus.add.mediation.energy.importCifE1;
import java.io.FileInputStream;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.dbunit.DataSourceBasedDBTestCase;
import org.dbunit.database.DatabaseConfig;
import org.dbunit.dataset.IDataSet;
import org.dbunit.dataset.xml.FlatXmlDataSetBuilder;

#RunWith(JUnit4.class)
public class DBUnitByBaeldungTest extends DataSourceBasedDBTestCase {
private Connection connection;
#Override
protected DataSource getDataSource() {
JdbcDataSource dataSource = new JdbcDataSource();
dataSource.setURL(
"jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;mode=Oracle;init=runscript from 'file:C:/Users/me/Projects/add/test-resources/de/kn/info/accountplus/add/mediation/energy/importCifE1/acctSys-schema.sql'");
dataSource.setUser("SA");
return dataSource;
}
#Override
protected IDataSet getDataSet() throws Exception {
IDataSet dataset = new FlatXmlDataSetBuilder().build(new FileInputStream("C:\\Users\\me\\Projects\\add\\test\\de\\kn\\info\\accountplus\\add\\resource\\myDatasetV1.xml"));
return dataset;
}
#Override
protected void setUpDatabaseConfig(DatabaseConfig config) {
config.setProperty(DatabaseConfig.FEATURE_QUALIFIED_TABLE_NAMES, true);
}
#Before
public void setUp() throws Exception {
super.setUp();
connection = getConnection().getConnection();
}
#After
public void tearDown() throws Exception {
super.tearDown();
}
#Test
public void readDB() throws SQLException {
ResultSet rs = connection.createStatement().executeQuery("select * from AP.ACCTSYS");
assertThat(rs.next(), equalTo(true));
System.out.println(rs.getString(1));
}
}
The schema file
DROP SCHEMA IF EXISTS AP;
CREATE SCHEMA AP;
create table if not exists AP.ACCTSYS
(
EINTRAG VARCHAR2(60) not null
constraint PK_ACCTSYS
primary key,
WERT VARCHAR2(512)
);
and the dataset file
<?xml version='1.0' encoding='UTF-8'?>
<dataset>
<AP.ACCTSYS EINTRAG="ONE" WERT="TWO" />
</dataset>
Can anyone see what I am missing
