Hi Experts

I am getting error while generating the dictionary table using the JPA Tools-->Generate Tables from Entities. Error is given below

Generation has failed due to invalid persistence unit. See the problem views for details.

In the problem view it is not giving the details it gave the particular table name cannot be resolved error only.

The persistence.xml content given below

<?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="DEM_PER_UNI" transaction-type="JTA">

  <jta-data-source>DEMO_JPA_ALIAS</jta-data-source>

  <class>demo.jpa.entity.DemoJPADo</class>

  </persistence-unit>

</persistence>

I have already done the connection to the dictionary DC from EJB Property-->Java Persistence

also enabled the Override the default schema from connection
