Hi:
I upgrade to Objectify-2.1.1 with GAE-1.3.6 and retest the guestbook
tutorial. I get the exception while persisting the greeting object to
the datastore. I notice the ObjectifyOpts is new in this 2.1.1 version.
[java] WARNING: /sign
[java] java.lang.IllegalArgumentException: opts:
com.googlecode.objectify.ObjectifyOpts is not a supported property type.

My constructors of genericDAO are:
@SuppressWarnings("unchecked")
public GenericDao(){ // DAO without transaction
super();
clazz = ((Class) ((ParameterizedType)
getClass().getGenericSuperclass()).getActualTypeArguments()[0]);
}
@SuppressWarnings("unchecked")
public GenericDao(boolean transactional){ // DAO with transaction
super(transactional);
clazz = ((Class) ((ParameterizedType)
getClass().getGenericSuperclass()).getActualTypeArguments()[0]);
}
and constructors for the greeting are:
public Greeting() { super(); }
public Greeting(boolean transactional) { super(transactional); }
public Greeting(User author, String content, Date date) {
this.author = author;
this.content = content;
this.date = date;
clazz = ((Class) ((ParameterizedType)
getClass().getGenericSuperclass()).getActualTypeArguments()[0]);
}
The sigGuestbookServlet has:
Greeting greeting = new Greeting(user, content, new Date());
greeting.storeGreeting();
resp.sendRedirect("/guestbook.jsp");
Any suggested solution?
Thanks
