HSQL-DB problem

[martinganserer]

Hello,

I created a small test project with an embedded HSQLDB.

Everything works fine, but I can not persist data. I don't get an exception but after making a commit no data is present in my table.

Here are some fragments of my source code:

?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence">
 <persistence-unit name="cust" transaction-type="RESOURCE_LOCAL">
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <class>com.kontron.entity.Customer</class>
 <class>com.kontron.entity.Country</class>
 <properties>
 <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
 <property name="hibernate.connection.url" value="jdbc:hsqldb:data/localDB"/>
 <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
 <property name="hibernate.connection.username" value="sa"/>
 <property name="hibernate.connection.password" value=""/>
 <property name="hibernate.max_fetch_depth" value="3"/>
 <property name="hibernate.show_sql" value="true"/>
 <property name="hibernate.hbm2ddl.auto" value="none" />
 </properties>
 </persistence-unit>
</persistence>

Here is my java code:

EntityManagerFactory emf = Persistence.createEntityManagerFactory("cust");
 EntityManager em = emf.createEntityManager();


 CustomerService src = new CustomerService();
 src.setEntityManager(em);

 em.getTransaction().begin();


 Customer cust = new Customer();
 cust.setId(2);
 cust.setName("Hallo AG");
 src.persistCustomer(cust);

 em.getTransaction().commit();

 em.close();
 emf.close();

What am I doing wrong?
