Actually I use it in a static method on a utility class, and call
SimpleDateFormat inside a synchronized block.

Consider placing the SimpleDateFormat as a local variable (within the
method) to avoid non-thread safe operations (guaranteed by the jvm
spec).

We had the same issue and went with writing a new converter (shown
below).
And then created a xwork-conversion.properties file pointing to it.
Z.
private final static SimpleDateFormat DATE_FORMAT = new
SimpleDateFormat("dd/MM/yyyy"); @Override public Object
convertFromString(Map context, String[] values, Class toType) throws
TypeConversionException { try { return
DATE_FORMAT.parse( values[0]); } catch (ParseException e) {
e.printStackTrace(); throw new
TypeConversionException("xwork.default.invalid.fieldvalue");
}
return null; } @Override public String convertToString(Map
context, Object object) { Calendar cal =
Calendar.getInstance();
cal.setTime((Date) object); try { return
DATE_FORMAT.format(object); } catch (Exception e) {
throw new TypeConversionException("xwork.default.invalid.fieldvalue");
} }
Can you patch a whole class?
What would be useful is parameterizable type converters, to specify
the date
format in this case. (they're not parameterizable, are they?)

The built-in type converter uses "uses the SHORT format for the
Locale
associated with the current request" according to the type
conversion
docs,
so yes, you'll need to do your own if you're using a different
input
format.
Looking through the XWork conversion code it's hard for me to
tell what
it's
*actually* doing, though :/

JSTL has the <fmt:formatDate> tag. If you want to do it in

rather
than your JSP, you can use SimpleDateFormat.
Be aware that SimpleDataFormat is not thread safe, so don't
assign it
to
a
static field or use it in a singleton. If you use it as an
instance
field
on an Action you'll be safe, since Actions are created per
request.
If you want a thread safe version of SimpleDateFormat,
Jakarta
Commons

has FastDateFormat: http://commons.apache.org/lang/

Hi
quick question, I can't find any specific mention of what I
want so I
assume I
have to code my own Converter.
I need a date in the ISO format YYYY-MM-DD
There is no converter that I can configure in the struts
package, is
there?
