* newbie alert * kodo persistence problem

Question

Trying to follow this oh so easy example:
http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/JDev11gExperience/JDev11gExperience.html
Here's the last few lines of the exception error...
The following providers:
kodo.persistence.PersistenceProviderImpl
org.apache.openjpa.persistence.PersistenceProviderImpl
Returned null to createEntityManagerFactory.
     at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:154)
     at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:83)
     at sample.model.JavaServiceFacade.<init>(JavaServiceFacade.java:12)
     at sample.model.JavaServiceFacade.main(JavaServiceFacade.java:19)
Process exited with exit code 1.
Connecting through an JDBC-ODBC bridge to an Ingres database (other locking issues make it difficult to connect using native ODBC driver)
fairly simple logic... connect to a single table then display one field out of the table to the console
[Tuserprof.java]
@Entity
@NamedQueries({
@NamedQuery(name = "TUserprof.findAll", query = "select o from TUserprof o")
[JavaServiceFacade.java]
public static void main(String [] args) {
final JavaServiceFacade javaServiceFacade;
javaServiceFacade = new JavaServiceFacade();
// TODO: Call methods on javaServiceFacade here...
List<TUserprof> emps = javaServiceFacade.getTUserprofFindAll();
for (TUserprof tUserprof : emps) {
System.out.println(tUserprof.getFirst_name());
Here's the persistence.xml file

Answer 1

NO CLUE on how to solve the errorFirst step STOP using a JEE server to figure out the problem.
Write a simple Java console app to test your ODBC set up. If you can't get that to work then you can't get it to work in JEE.
