      Generates entities with EJB3 annotations with Reverse Engineering Strategy :

      DeletagatingReverseEngineeringStrategy .java
         
@Override
public Properties getTableIdentifierProperties(TableIdentifier dentifier)      {
 Properties properties = new Properties();
 properties.put("sequence", "S_"+identifier.getName());
 return properties;
}
  
public String getTableIdentifierStrategyName(TableIdentifier identifier) {
 return "sequence";
}

      Generates entities with EJB3 annotations with Reverse Engineering Strategy : DeletagatingReverseEngineeringStrategy .java @Override public Properties getTableIdentifierProperties(TableIdentifier dentifier) { Properties properties = new Properties(); properties.put( "sequence" , "S_" +identifier.getName()); return properties; } public String getTableIdentifierStrategyName(TableIdentifier identifier) { return "sequence" ; }

      When generating entities with EJB3 annotations with a strategy set to "sequence", Hibernate tools generates POJOs with non unique javax.persistence.SequenceGenerator name "generator". But according to the Java documentation :

      String name (Required) A unique generator name that can be referenced by one or more classes to be the generator for primary key values.

      See javadoc

      Exemple of generated code with 4.0.0 Alpha1:

      @SequenceGenerator(name = "generator", sequenceName = "S_CLIENT")
   @Id
   @GeneratedValue(strategy = SEQUENCE, generator = "generator")
   @Column(name = "CLIENT_ID", unique = true, nullable = false, precision = 22, scale = 0)
   public long getClientId() {
      return this.clientId;
   }

      Source code can be seen here.
      So looks like the //TODO comment is right and it should generate a unique name atribute. sequencename+"generator" would be a good name.
      It would even be better if we could define this name in reveng.xml or/and in a DelegatingReverseEngineeringStrategy class.
