[jboss-user] [EJB 3.0] - Mapping Problem

[Sukar1205]

I am getting an error when I run Jboss server that says..

  | --- MBeans waiting for other MBeans ---
  | ObjectName: persistence.units:jar=SourceCode.jar,unitName=SourceCodePU
  |   State: FAILED
  |   Reason: javax.persistence.PersistenceException: org.hibernate.MappingException: Repeated column in mapping for entity: EntityBean.KnowledgeBase column: projectID (should be mapped with insert="false" update="false")
  |   I Depend On:
  |     jboss.jca:service=DataSourceBinding,name=SQL
  |   Depends On Me:
  |     jboss.j2ee:jar=SourceCode.jar,name=ClassificationBeanFinal,service=EJB3
  | 

This is my code


  | @JoinColumn(name = "projectID", referencedColumnName = "projectID")
  |     @ManyToOne
  |     private Project projectID;
  | 
what is the synatx to insert = false and update = false... I tried adding it in JoinColumn but still giving me an error.
THanks in advacne.
