If this is any help i do this on a per class basis by using annotations on 
my ecore. Here is a header template from  
project-name/jet-templates/Header.javajetinc

where my dynamic template directory is set to /project-name/jet-templates



------------8<------------8<------------8<------------8<------------8<------------8<

<%
 String xxxx_fileComment = "comment missing!!";
 
 final GenBase xxxx_genBase = argument instanceof GenBase ?  (GenBase) 
argument : (GenBase)((Object[])argument)[0];
 org.eclipse.emf.ecore.EAnnotation xxxx_EcoreClassAnnotation =  
xxxx_genBase.getEcoreModelElement().getEAnnotation("http://www.leeds.ac.uk/xxxx/yyyy";);
 if (xxxx_EcoreClassAnnotation != null) {
   org.eclipse.emf.common.util.EMap xxxx_details = 
xxxx_EcoreClassAnnotation.getDetails();
   if (xxxx_details.containsKey("file comment")) {
       xxxx_fileComment = (String)xxxx_details.get("file comment");
       
   }
 }
%>
<% for (String xxxx_line : xxxx_fileComment.split("\n")){ %>
* <%=xxxx_line%>
<%}%>
*/

and here is a sample segment of ecore model

------------8<------------8<------------8<------------8<------------8<------------8<

              <eClassifiers xsi:type="ecore:EClass" name="Wibble" 
eSuperTypes="#//wobble/object">
                 <eAnnotations 
source="http://www.leeds.ac.uk/xxxx-ecore-1.0/xxxx_genmodel";>
                   <details key="file comment" value="whatever copyright 
code you need"/>
                 </eAnnotations>

hope this helps
