The only use I can think of is to save it for future use, as it is too early to do any of the following *important* things:
1. Make a
JDBC call, because transaction context is unavailable.
2. Invoke other beans, because security context is unavailable(Even though the bean is allowed to lookup another bean, it is not allowed to invoke any methods)
So save the EntityContext/SessionContext and wait until the container allows you to play with it
