Hi All,
I am at a lost on why the following error has taken place when persisting a newly added table (entity class) from an EAR application Client (Java EE 5 - GF 2.1, JDK1.6.17):
04/06/2010 10:50:41 AM com.sun.enterprise.appclient.MainWithModuleSupport <init>

This new entity class has recently been added to an existing working EAR project that is made up of entity classes associated with one persistent unit and a number of session beans. The same persistent unit SecurityDB-PU is used by the newly added table.

Data from earlier tables are still been added (persisted) correctly which suggests that the persistent unit is intact.
The persistence.xml is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="
http://java.sun.com/xml/ns/persistence" xmlns:xsi="

<properties>
<property name="toplink.ddl-generation" value="drop-and-create-tables"/>
</properties>
</persistence-unit>
</persistence>
Any assistant would be much appreciated.
Thanks,
Jack
