Do you mean that the converter applies thru my all application? As much as I know - copyProperties() is a static method of BeanUtils so I'm don't really know where (if at all) BeanUtils is instanciated.

If yes - how does >BeanUtils.copyProperties() know which converter to use (both the above >properties are the same type - Timestamp)? It does not. Frankly, this is a limitation of the BeanUtils design model. It assumes for any given process (instance of BeanUtils), a single conversion strategy applies to all objects of a given type. I have solved this sometimes by writing a Converter which expects a few specific variations of a date format and then tests the string length to look up the format string -- obviously this is imperfect, but it may work for you. (something like this: if (str.length() == 10) { // parse date using "mm/dd/yyyy" } else if (str.length() == 8) { // parse date using "hh:mm a" } else { throw new IllegalArgumentException("Unrecognized date format"); } Joe -- Joe Germuska [EMAIL PROTECTED] http://blog.germuska.com "Narrow minds are weapons made for mass destruction" -The Ex --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
