Dates one day behind after java upgrade to 1.6.0_27

Question

I have upgraded from Java 1.5.0_06 to 1.6.0_27
After the upgrade ,I saw that dates are a day behind.All dates that lie between November 6th to March 10th are correct but dates
lying between March 10th to November 5th for any year are wrong.(one day behind)
Is it something to do with DayLight saying.
I am using GMT-5 Eastern Time(US & Canada) and Server is set to automatically adjust time coressponding to day light saving.
I checked,I get the date correct from database and in the factory class also it is correct,in the servlet it is correct but my Viewclass which calls this servlet shows date one day behind.
I am doing no conversion ,the date fetched from database is stored like
java.sql.Date beginDate= resultSet.getDAte("BeginDate")
Schedule.setBegindate(beginDate)
In the Schedule Object ,the beginDAte is of type Date.
I am adding all dates to a treeset.I do a printout just after setting,it is correct
But in my view class ,its one day behind,no manipulation is done.Dont know why is the day incorrect.
IS it because of Java version.
Please help

Answer 1

As I mentioned That
My view class TestView code is some what like this
public class TestView extends JFrame
public TestView(URL url, AppletContext appletContext)
this.appletContext = appletContext;
SwingUtilities.invokeLater(new Runnable() {
public void run()
testCommand test= new GetDatesCommand();//call factory class which fetches result from database
Object returnValue = TestUtils.callServlet(test);//calls the servlet .
if( returnValue instanceof TreeSet )
TreeSet testSet= (TreeSet)returnValue;
TestView.setDate(testSet));
I am calling this constructor of viewtest class from my LoginTestApplet
public class LoginTEstApplet extends JApplet
public LoginApplet()
TimeZone.setDefault(TimeZone.getTimeZone("EST"));
LoginTestActionperformed()
new testView(getDocumentBase(), this.getAppletContext());
As I mentioned the values of dates as fetched from database ,factory class and getDatesCommand class prints fine.Its just inside this class after the call to servlet ,it displays wrong date.
I have an applet ,LoginTestApplet which is the entry point for my application.Inside the default constructor ,I am doing
TimeZone.setDefault(TimeZone.getTimeZone("EST"));
I have mentioned in my second post what results it shows for getDefaults.
I know its very strange ,the dates gets one day behind immedately only in the view class not in the servlet or the factory class.
Please let me know if I need to post some more data .
