    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>java:jboss/datasources/ypay</jta-data-source>
    <properties>
     <!-- Properties for Hibernate -->
     <!-- <property name="hibernate.hbm2ddl.auto" value="validate" /> -->
     <property name="hibernate.show_sql" value="false" />
     <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />

@Andrei It was wotking in previews projects, in eclipse juno with both files, now in kepler I have problems, I dont see the reason why both files should not be there — simonC
@simonC Is it not the case that if META-INF/persistence.xml is already on your classpath, you don't need to explicitly select a persistence unit? — JamesB
@JamesB is I remove the persistence unit entry from the hibernate edit configurations the problem persists, in this case it says "persistence unit not found : null" — simonC
@Andrei ... i nead hibernate-cfg.properties only for the purpouse of reverse engineering and hql query testing via jboss hibenrate tools in eclise, the aplication itself uses a datasource ... I have used many times both files in an aplication withowt problems — simonC
Do you have a single persistene.xml file in your project? Don't you have another one in test/resources/META_INF? PS: I deleted my comments as I do not consider them useful. — Andrei I

You need a META-INF/persistence.xml with

<persistence-unit name="ypay">

(usually put it in WEB-INF/classes/META-INF. When using maven you can try placing it in src/main/resources/META-INF)

Please refer to this doc for details.
