Hi,
could someone tell me if there is still the need to write a wrapper

Thank you

all objects inside a collection need to have a get/set method so

can store them? Is it possible to store just strings in a vector and
save
it? What would the maping file for that look like? Is that possible
at all?
Thanks for your help.

Set up an object that has a vector data member that holds the
strings. It is not enough to store java.lang.String objects
in the vector. If you want the elements of the vector to be
persisted automatically then the elements of the vector must
depend on the master object (the object containing the vector).
You must create a simple wrapper object that holds the string
value together with a reference to the parent object. You must
also specify that the wrapper object depends on the master (use
the  depends attribute in the mapping file).

Antonio,
The statement above by Peter is one way to do this. Currently Castor 
does not support this feature.
