OData Service via Java JPA Error

Hello everyone,

currently i am trying to set up an OData Service via Java JPA. I created a JPA Model with all my entities and also create a pom.xml to load all dependencies for Olingo as described in this blog post:

Creating OData Service for HANA Cloud Platform JPA based Web Application and extend OData processing using custom logic

However, everytime when i try to puslish my code to the hana trial server i receive the following error message:

Problem while publishing

Something is wrong with the database configuration. My persistence.xml looks as follows:

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistencehttp://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

    <persistence-unit name="trackingclaim" transaction-type="RESOURCE_LOCAL">

        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

        <class>ibm.trackingclaim.model.Claim</class>

        <class>ibm.trackingclaim.model.ClaimAttachment</class>

        <class>ibm.trackingclaim.model.ClaimObjectCategorie</class>

        <class>ibm.trackingclaim.model.ClaimState</class>

        <properties>

            <property name="eclipselink.ddl-generation" value="create-tables"/>

            <property name="eclipselink.jpql.parser" value="org.eclipse.persistence.queries.ANTLRQueryBuilder"/>

        </properties>

    </persistence-unit>

</persistence>

The JPAEntityManagerFactory:

public class JPAEntityManagerFactory {

    public static final String DATA_SOURCE_NAME= "java:comp/env/jdbc/DefaultDB";

    public static final String PERSISTENCE_UNIT_NAME="trackingclaim";

    private static EntityManagerFactory entityManagerFactory = null; 

    public static synchronized EntityManagerFactory getEntityManagerFactory()

        throws NamingException, SQLException {

        if (entityManagerFactory ==null)

        {

            InitialContext ctx = new InitialContext();

            DataSource ds = (DataSource) ctx.lookup(DATA_SOURCE_NAME);

            Map<String, Object> properties = new HashMap<String, Object>();

            properties.put("javax.persistence.nonJtaDataSource", ds);

            entityManagerFactory = Persistence.createEntityManagerFactory(

                    PERSISTENCE_UNIT_NAME, properties);

        }

        return entityManagerFactory;

    }

}

The TrackingCliamServiceFactory.

public class TrackingClaimServiceFactory extends ODataJPAServiceFactory {

    @Override

    public ODataJPAContext initializeODataJPAContext()

            throws ODataJPARuntimeException {

        ODataJPAContext oDataJPAContext = this.getODataJPAContext();

        try {

            EntityManagerFactory emf = JPAEntityManagerFactory.getEntityManagerFactory();

            oDataJPAContext.setEntityManagerFactory(emf);

            oDataJPAContext.setPersistenceUnitName(JPAEntityManagerFactory.PERSISTENCE_UNIT_NAME);

            return oDataJPAContext;

        } catch (Exception e) {

            throw new RuntimeException(e);

        }

    }

}

Somebody know why this is not working with JPA.

Best regards
