RE: How To: String --> sql.Date and String --> java.util.Date

Thanks for the info.

I should probably mention that I don't know if BeanUtils.copyProperties will 
copy a string to a sql.Date correctly or not.  I'm having problem with the 
String to Date converstion ==> have put it in my jsp yet.  I wonder if anybody 
know for sure if that will work.  If not how do I go around this.

I am not familiar with the tools that you're using, but I know that
java uses introspection to discover javabeans' properties, which means
that it would look at the return value of the 'set' methods and
determine the return type -- perhaps this is how it knows how to map
it!

If you don't need hh:mm:ss, you can set a different parse-string using
the following:

 Symbol   Meaning                 Presentation        Example
 ------   -------                 ------------        -------
 G        era designator          (Text)              AD
 y        year                    (Number)            1996
 M        month in year           (Text & Number)     July & 07
 d        day in month            (Number)            10
 h        hour in am/pm (1~12)    (Number)            12
 H        hour in day (0~23)      (Number)            0
 m        minute in hour          (Number)            30
 s        second in minute        (Number)            55
 S        millisecond             (Number)            978
 E        day in week             (Text)              Tuesday
 D        day in year             (Number)            189
 F        day of week in month    (Number)            2 (2nd Wed in July)
 w        week in year            (Number)            27
 W        week in month           (Number)            2
 a        am/pm marker            (Text)              PM
 k        hour in day (1~24)      (Number)            24
 K        hour in am/pm (0~11)    (Number)            0
 z        time zone               (Text)              Pacific Standard Time
 '        escape for text         (Delimiter)
 ''       single quote            (Literal)           '


These are specified in the API for java.text.SimpleDateFormat
