Hi All,

I am using hibernate as my persistence provider and postgre as my DB. 

My persistence.xml looks like below

<persistence-unit name="titan" transaction-type="JTA">
                    <property name="hibernate.dialect" value=  "org.hibernate.dialect.PostgreSQLDialect" />
                     <property name="*hibernate.hbm2ddl.auto*" value="*update*" />
                     <property name="hibernate.show_sql" value="true" />
                     <property name="hibernate.format_sql" value="false" />
                     <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>
                     <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/Entity"/>
                     <property name="hibernate.connection.username" value="*****"/>
                     <property name="hibernate.connection.password" value="****"/>

I have table Cabin, Customer and Address under my table Entity. When i deploy my jar and start the server , again a new table is created  as cabin, customer and address. :0  I thought with value = "update"  for  hibernate.hbm2ddl.auto, it should not create any table and should only update the data.

When i deleted the table from DB, then there was no table found message when the jboss is up. I don't want to duplicate the tables. 

What could be the issue ?
