I would really like to get some reply from Jboss group as well. With cmp 1.1 I've been declaring my date types to be java.sql.Timestamp and was doing conversions in the getter and setter methods. Unfortunately, with cmp 2.0 those getter and setters are abstract and for us it will be a big change to convert from java.util.Date to java.sql.Timestamp everywhere in the system. We need to find out for sure if that conversion is the only hope for us. Really appreciate the help.
