Versioning Services Problem

[Emanuele Lombardi]

Hi,
I'm working on versioning services, but I have a problem :The Updating of 
CmisObject's properties.

My procedure:
First I set the property value by CMISObject#setValue method and last I call 
the save method. The save method if is an update require a server method not 
yet implemented and I try to implement it (the method is 
"org.apache.chemistry.atompub.server.CMISObjectsCollection.putEntry(ObjectEntry,
 String, Date, List<Person>, String, Content, RequestContext)") But my 
implementation doesn't work. If I'm not able to save the modified properties on 
the repository I can't test the versioning services.
Can you help me? I attach my code.

Thanks

Emanuele

   public void putEntry(ObjectEntry object, String title, Date updated,
            List<Person> authors, String summary, Content content,
            RequestContext request) throws ResponseContextException {
        Entry entry = null;
        try {
            entry = getEntryFromRequest(request);
        } catch (ResponseContextException e) {
            e.printStackTrace();
        }
        entry.setTitle(title);
        entry.setEdited(updated);
        for (Person a : authors) {
            entry.addAuthor(a);
        }
        entry.setContent(content);
        entry.setSummary(summary);

        String link = addEntryDetails(request, entry, null, object);

        buildCreateEntryResponse(link,entry);
    }
