JPA Namespace missing

Question

Hello,
I'm trying to follow "SAP JPA 1.0, EJB 3.0 and WebService -Modeling Your First JPA Entity in CE 7.1" tutorial.
All is running well till I try to generate the DDL file (on my ejb project, I right click and select JPA Tools).
Each time I'm getting the same error : "ERROR:  Namespace in FORMINFO is missing (Rule: namespace_suffix)" where FORMINFO is the name of the table to which my JPA entity FormInfo is linked.
I get also the same error in JPA entity class.
I was not able to fin a way to solve this issue. Anyone can help?
Thanks,

Answer 1

I am working with 7.2 ... and it seems that the DDL is not generated (at least it is nowhere I searched )
It initially complained that it was not connected to the dictionnary.
After I restarted the IDE, it did not complained anymore
The only major difference I find between the Tutorial and my project is the file persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" 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/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  <persistence-unit name="LocalDevelopment~LocalDevelopment~employee_app~demo.vertomind.com">
    <jta-data-source>EMPLOYEE_DS</jta-data-source>
  </persistence-unit>
<!--
Trying to map the name used generated Errors
  <persistence-unit name="EMPLOYEE_PU">
  </persistence-unit>
   -->
</persistence>
\T,
I feel like an idiot ...
I created a new Connection employee_conn2 and now DDL generation worked ....
Grrrrrrrrrrrr ...
