[rules-users] Drools Human Task Service Persistence

Hi All, I have been trying to persist the Human TasK service to Oracle. And I got the below error. Please check my persistence.xml file and the error that I have recieved. It seems this is happening because of some oracle reserved words are used to name the columns. Any suggestions??? on this Topic????? persistence.xml ============ <persistence-unit name="org.drools.task"> <class>org.drools.task.Attachment</class> <class>org.drools.task.Content</class>
