'Ello,
I'm writing some support software and want to use EJB and a 3-tier model,
because I think that the best option. I can't, however, figure out how to
allow the users of the software to add fields to the beans in the datalayer
without having them to rewrite my beans.
My first guess was to use extension of my databeans but that means chancing
the type of the variables used to store the home and remote interface's in
my 2nd tier (or doesn't it?) and rewriting the home interface because of the
return types of the create method and some of the findBy methods.
I think this is quite a common problem, but I can't seem to find anything on
how to solve it. Can anybody tell me how to tackle this or point me to some
possible solutions / resources?
Thanks a lot,
Sandigo.
