Thanks a lot to Vartan, Dies and Robert for your comments. I seem to have missed Dies' message the first time round, so I am glad that Robert took it up.
The situation as described by Dies is perfectly correct. As for mapping Hibernate collections to arrays, I think I could replace the existing set with arrays. (the only limitation being this: " Please note that Hibernate does not support bidirectional one-to-many associations with an indexed collection (list, map or array) as the "many" end, you have to use a set or bag mapping."). In this case however, I'd lose the code generation capabilities from the Hibernate tool I'm working with, which for some reason assumes Set as the default for collections. I presume going down the adapter road might the most feasible. I have some manager classes for the POJOs, which provide a facade to the database (add, delete, update etc.). These classes could also serve as the adapters to convert the WSDL2Java generated objects that are used on the client side to POJOs used on the server side. I hope this makes sense, I don't really have that much experience (as you may have guessed). Cheers, Martin > I agree with dies - just one small caveat.
