Thanks,
I simply was a little confused about the use of the util.DateConverter
and webapp.action.DateConverter .
I have used some of yours and followed your advice to use Calendar
instead of Timestamp to adjust the webapp.action.Converter and the
util.DatuUtils to fit my needs.
It's working alright. I even use the client side TimeZone to convert the
Calendar from the usersTimeZone to the system and vis versa. That way
times in the system have a correct value for the appropriate timezone.
For this I used this
http://j2eecookbook.blogspot.com/2007/06/formatting-date-to-client-timezone.html
to get users timezone and modified the LocaleFilter.
What I do in the DateUtil to Convert is the following:
from StringToCalendar:
Calendar calendar = null;
Date transfer;
SimpleDateFormat df;
df = new SimpleDateFormat(aMask);
if (log.isDebugEnabled()) {
log.debug("converting '" + strDate + "' to date with mask '"
+ aMask + "'");
}
try {
df.setTimeZone(usersTimeZone);
transfer = df.parse(strDate);
calendar = Calendar.getInstance();
calendar.setTime(transfer);
} catch (ParseException pe) {
throw new ParseException(pe.getMessage(), pe.getErrorOffset());
}
return calendar;
from CalendarToString:
SimpleDateFormat df = null;
String returnValue = "";
if ( aCalendar == null ) {
log.error("aCalendar is null!");
} else {
df = new SimpleDateFormat( getDateTimePattern() );
df.setTimeZone( usersTimeZone );
returnValue = df.format( aCalendar.getTime() );
}
return (returnValue);
I would greatly appreciate some thoughts and opinions on this.
kind regards

You might try creating a new converter that specifically supports

Hi,
I am trying to figure out how to use the DateConverter in Appfuse
2.0.2 to
convert Timestamp to String and vis versa.
At first I used java.util.Date and the DateConverter worked fine,
than I
changed the type in the POJOs to java.sql.Timestamp. To have the
java.sql.Timestamp be converted I also added
java.sql.Timestamp=com.app.util.DateConverter to the
xwork-conversion.properties.
But now running under mvn jetty:run (not quite sure what version -
using
6.1.9 maven-jetty-plugin) the DateConverter does not "kick-in" for the
java.sql.Timestamp values. For Date still works great.
What am I missing?
Thanks and kind regards
