[hibernate-dev] Help to intoduce dynamic parameters into a message

Hi, I'm a newbie. When validating a class, how to use values of dynamic parameters into a validation error message? I explain, I want to take into account parameters which will be included into the text of the message referenced by EXCEPTION_ID id into a resource file. What is the best mean to do please? 1) @FilenameUnicity(message = "EXCEPTION_ID", (paramsToPutIntoTheMessage)???, groups = { Default.class, Specific.class }) 2) MessageInterpolator??? Thanks a lot.
