When I insert a single record into a table, it is not run and I find log as follow:

Seasar.Framework.Aop.Interceptors.TraceInterceptor: DEBUG 2009-06-13 02:00:09,390 [4] BEGIN SeaserBlank.AppCode.Common.Logic.IMemberLogic#insert(SeaserBlank.AppCode.Common.Entity.Member)

In Dao Interface, I use build-in insert(EntityName objEntityName) function.
I don't understand that I used insert() function but actually it became Seasar.Extension.ADO.Impl.BasicSelectHandler
Would anyone explain for me.
Thanks alot!
