  1. POA bug in Java XMLGregorianCalendar conversion to a Java util.Date?
    text
    copied!<p>I'm writing a date/time value to an XML file by reading the date from a RAP based UI as a Java Date object, and passing it as an <code>XMLGregorianCalendar</code> object to actual file writing code. The corresponding classes are auto generated and I don't have control over them. The date I entered was:</p> <blockquote> <p>03-03-1933:03:03:03.</p> </blockquote> <p>It got converted to the following string when written in the file:</p> <blockquote> <p>1933-03-03T03:03:03.161+05:53</p> </blockquote> <p>Now, when I read the date back to show it in the UI for edit, it appeared there as:</p> <blockquote> <p>03-03-1933:03:03:23</p> </blockquote> <p>Note the extra 20 seconds added to the actual seconds value.</p> <p>Why is this happening? Is it some bug in the API? Any help will be much appreciated!</p> <p>Relevant code:</p> <p>1) Converting to <code>XMLGregorianCalendar</code>from <code>Date</code>:</p> <pre><code>GregorianCalendar calendar = new GregorianCalendar(); calendar.setTimeInMillis(date.getTime()); XMLGregorianCalendar date2; date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(calendar); // pass 'date2' to file writing code </code></pre> <p>2) Converting to <code>Date</code> from <code>XMLGregorianCalendar</code>:</p> <pre><code>XMLGregorianCalendar cal = getDateFromFile(); // XML date read from file Date date = cal.toGregorianCalendar().getTime(); // show Date object in UI, dateCtrl and timeCtrl are SWT DateTime objects GregorianCalendar calendar = new GregorianCalendar(); calendar.setTime( date ); dateCtrl.setDate( calendar.get( GregorianCalendar.YEAR ), calendar.get( GregorianCalendar.MONTH ), calendar.get( GregorianCalendar.DAY_OF_MONTH ) ); timeCtrl.setTime( calendar.get( GregorianCalendar.HOUR_OF_DAY ), calendar.get( GregorianCalendar.MINUTE ), calendar.get( GregorianCalendar.SECOND) ); </code></pre>
