I have been using java serialization for persisting my POJOs in files but now i need to store my POJOs in database and needs collaboration in my application so i am trying to explore possibilities with EclipseLink.
If i have saved my POJO and i have to do alterations in class like add/delete/rename class properties then will i able to retirve saved POJO properly from saved resources?
1 - if i add a new class member variable to my java class then will i be able to retrieve already saved POJOs properly (in java serialization, Object can be reterived and the newly added property contains default value)?
2 - if i delete a class member variable in my java class then will i be able to retrieve already saved POJOs properly (in java serialization, it works well as long as serial version id does not change)?
3 - if i rename a class member variable in my java class then will i be able to retrieve already saved POJOs properly?
thanks for helping....
Cheers,
