GWT Doesnt support this java APi. It's explicit in documentation pages http://code.google.com/intl/fr/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideDateAndNumberFormat
GWT does not provide full emulation for the date and number formatting classes (java.text.DateFormat, java.text.DecimalFormat, java.text.NumberFormat, java.TimeFormat, et cetera). Instead, a subset of the functionality of the JRE classes is provided by com.google.gwt.i18n.client.NumberFormat and com.google.gwt.i18n.client.DateTimeFormat GWT provides the DateTimeFormat class to replace the functionality of the DateFormat and TimeFormat classes from the JRE. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
