GWT passing value objects
In my current project I am building an interface where I will be passing huge list of values to the csv servlet class( i need to write the data to csv file) . Currently I am using window.open() method to pass the values to the csv class servlet. When the list of values to be send are huge the inbuilt jetty server closes the connection. Is there any framework in GWT i can use to send the values as a objects to the csv servlet class. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Hi all,
this particular logic in java returns the logic what I am asking for but
GWT does not support java util package of calender. Can someone help me
converting this logic with GWT util package
Calendar cal = Calendar.getInstance();
cal.setTime(new SimpleDateFormat("MMM").parse("July"));int monthInt =
cal.get(Calendar.MONTH) + 1;
