Hello
In your User bean you have an attribute called as ID, which will have get & set method like getId() and setId().
I will suggest rename this attribute such that it will have first minimum 3 letters in small case like intId or strId, then change the get/set method respectively like getStrId() or getIntId().
This is a problem with java reflection that when you have attribute which will have 1 or 2 chars in the start of varialbe name, then some time reflection fails to call that methods get-set method.
You change the varaible name and hopefully everything will work fine.
