// This is a working example of POSTing a string (representing a block of XML) to a web server try { URL url = new URL( argUrl ); URLConnection con = url.openConnection(); // specify that we will send output and accept input con.setDoInput(true); con.setDoOutput(true); con.setConnectTimeout( 20000 ); // long timeout, but not infinite con.setReadTimeout( 20000 ); con.setUseCaches (false); con.setDefaultUseCaches (false); // tell the web server what we are sending con.setRequestProperty ( "Content-Type", "text/xml" ); OutputStreamWriter writer = new OutputStreamWriter( con.getOutputStream() ); writer.write( requestXml ); writer.flush(); writer.close(); // reading the response InputStreamReader reader = new InputStreamReader( con.getInputStream() ); StringBuilder buf = new StringBuilder(); char[] cbuf = new char[ 2048 ]; int num; while ( -1 != (num=reader.read( cbuf ))) { buf.append( cbuf, 0, num ); } String result = buf.toString(); System.err.println( "\nResponse from server after POST:\n" + result ); } catch( Throwable t ) { t.printStackTrace( System.out ); }

This function converts a local date to GMT. This version corrects the bug common to this type of conversion where the date is incorrectly converted when the time is close to the DST crossover. WARNING: This code is for printing/string-representation only, the millis value of the returned date is NOT in GMT. private static Date cvtToGmt( Date date ) { TimeZone tz = TimeZone.getDefault(); Date ret = new Date( date.getTime() - tz.getRawOffset() ); // if we are now in DST, back off by the delta. Note that we are checking the GMT date, this is the KEY. if ( tz.inDaylightTime( ret )) { Date dstDate = new Date( ret.getTime() - tz.getDSTSavings() ); // check to make sure we have not crossed back into standard time // this happens when we are on the cusp of DST (7pm the day before the change for PDT) if ( tz.inDaylightTime( dstDate )) { ret = dstDate; } } return ret; }
