Inverse serialization of objects error: java.lang.ClassNotFoundException

The data that is received by a bug is always said to be missing from the class. I looked at the serialization of the implementation of the class name is also the same and then in the server to receive the object when the general report this do, online search a lot of the last found that the original package name is not the same, resulting in two different classes of the program is really a strict thing ah paste code to everyone to see

Hint class can not find, but in fact the class file is actually exist, then the Internet search. Sure enough to find the answer.

Can participate in the article: http://www.javapractices.com/topic/TopicAction.do?Id=45

The main two points:

1) need the same package name

2) the same serialization ID
