org.apache.openjpa.util.UserException - ConnectionDriverName

[Scherer, Annette]

Hello,

I have a problem, when trying to create an EntityManager.

I'm using the persistence.xml beneath, which indicates to use managed 
transactions and managed ConnectionFactoryMode (see below).

 <persistence 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/persistence 
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd";
        version="1.0">
        <persistence-unit name="Selektionen_DB">
                <provider>
                        org.apache.openjpa.persistence.PersistenceProviderImpl
                </provider>
                <jta-data-source>java:comp/jdbc/selektionendb</jta-data-source>
                <properties>
                        <property name="openjpa.TransactionMode" 
value="managed"/>
                        <property name="openjpa.ConnectionFactoryMode" 
value="managed"/>
                        <property name="openjpa.jdbc.DBDictionary" value="db2"/>
                        <property name="openjpa.jdbc.Schema" value="T7"/>
                </properties>
        </persistence-unit>
</persistence>

Configuration Deploymentdescriptor Session Bean:
jdbc/selektionendb is configured in Deployment Descriptor of the SessionBean 
that contains the JPA Operation

Configuration JDBC provider on WAS70:
DB2 Universal JDBC Driver Provider  
One-phase commit DB2 JCC provider that supports JDBC 3.0. Data sources that use 
this provider support only 1-phase commit processing, unless you use driver 
type 2 with the application server for z/OS. If you use the application server 
for z/OS, driver type 2 uses RRS and supports 2-phase commit processing. 

Configuration DB Source on WAS70:
Selektionen_DB  jdbc/selektionendb    
DB2 Universal JDBC Driver Provider    
DB2 Universal Driver Datasource   

Log Output:
Beim Initialisieren der Konfiguration sind Fehler aufgetreten: 
<openjpa-1.2.1-SNAPSHOT-r422266:686069 fatal user error> 
org.apache.openjpa.util.UserException: Es muss der Name eines JDBC-Treibers

This exception is thrown, wenn executing the createEntityManager() Statement 
(see below)
this.setEmf(Persistence.createEntityManagerFactory("Selektionen_DB"));
this.getEmf().createEntityManager();    


Thank you for help
