Hi there, thank you very much for your reply.
How would you expect the period to be passed to the java.util.Date class?The query uses the "period" column just to group the resulting records; I really only care about the "expense_date" column (which gets mapped properly to java.util.Date, as I can see when I turn on the debugger in Eclipse). So I expect a collection of Date instances (this works in Eclipse, but not in Maven). Do you have any ideas how I can trace what Ibatis is doing under the covers? I tried enabling logging on org.apache.ibatis, but this doesn't tell me much. Thanks a lot. Cheers, Javier. __________________________________________________________________ Looking for the perfect gift? Give the gift of Flickr! http://www.flickr.com/gift/
