My application needs to run on different databases.
I want to use iBATIS because it seems to be easier to handle. However it does not appear to support multiple databases using a single set of mapping files.
I think Hibernate does it by simply changing the Dialect tag.
Is this true?
Any experience using iBATIS?
Thanks.
Bruce.

As usual: it all depends.
Hibernate supports trivial DB differences better than iBatis, if you have control over DB schema than I would suggest using Hibernate. However Hibernate may still require different mapping files in certain cases.
iBatis is your best friend if:
you need to take full advantage of features in different databases;
you need flexible report type querying;

And of course you can mix and match:
