How can I write mapping documents for this classes. Is there any way to save vectors?

thanks in advance...

Here's one way, I think. Though with Set, not a Vector. You may use Set, List, Map.

See the reference for more options.

I know i can do it that way. but there is a peace of code that i cannot change and they have used a vector instead of list. so is there any way of mapping vector by hibernate.
If i cannot do it by hibernate then comes the question, can i use hibernate and jdbc together or is there any drawbacks of using them together. because if there is no way of mapping vector by hibernate i have to use jdbc for this part of the project.

Maybe you could instead use the List mapping and create some kind of Vector to List converter.
