Please just remember that just because tools (like eclipse and others) warns about a missing serialversionUID it 
does not mean it should be there. Simon Kicthing described it well in HBX-444:

"When you declare a serialVersionUID you're also declaring that you are aware of all the issues regarding serialising one version of a class and reimporting the serialized data into a different version of the class, and are promising to update the serialVersionUID whenever you make an *incompatible* change to the class.

However most people don't have a clue what is and what is not a serialization-incompatible-change to a class. In this situation I think the default behaviour (which is that the serialization mechanism declares incompatibility if *any* change occurs to the class) is much safer than having an auto-generated serialVersionUID on the class resulting in potientially corrupted objects on deserialization."

Just my 2 cents...
