My package is anything with blogger at the front. I caught the Throwable error and called printStackTrace() on the error there It seems that having any data in the "List<Comment> comments" in the Content.java causes the serialization error. Even when I've removed all the data from the Serializable class Comment.java. So it has nothing but a constructor. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
