hi all

i have a java program that sends an email with .vcs file as an attachment for meeting request. When user opens the .vcs file and clicks on save and close button, he can see his outlook calendar blocked for the time slot specified.
Suppose the meeting gets cancelled, user should get a cancelled .vcs file.
on saving the file, appointment from outlook calendar should vanish.
iam stuck with cancellation part.
can anybody please suggest me how to create a .vcs file to delete appointment from outlook calendar ...

thanks in advance.

hi Jesper

my very first statement was .....

i have to convert date format of "2008-03-30T05:00:00.000+02:00" to
MM/dd/yyyy hh:mm a

i think this clearly explains that i want to convert datetime in "2008-03-30T05:00:00.000+02:00" format to MM/dd/yyyy hh:mm a format.

hi laxman

thanks for your response.

as of now iam using this code

SimpleDateFormat sdf1 = new SimpleDateFormat("MM/dd/yyyy hh:mm a");
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String s1 = "2008-03-30T15:30:00.000+02:00";
s1 = s1.substring(0, s1.indexOf('.'));
try {
System.out.println("Result==> "+sdf1.format(sdf2.parse(s1)));

hi Henrique

i tried what Jesper said..

Date now = new Date();
System.out.println("date--> " + now);
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
String s = df.format(now);
String result = s.substring(0, 26) + ":" + s.substring(27);
System.out.println("result--> " + result);

output:

date--> Fri Mar 14 10:27:31 IST 2008
result--> 2008-03-14T10:27:31.197+05:0

"2008-03-14T10:27:31.197+05:0" is not the format i want my result to be.
it should be in MM/dd/yyyy hh:mm a format

"yyyy-MM-dd'T'HH:mm:ss.SSS" corresponds to "2001-9-11T18:15:00.000"

hi all

iam trying to convert datetime in one timezone to corresponding datetime in
other timezone. iam using jdk 1.5 and jodatime 1.5.1

Iam trying to convert March 30th 2008 2am in Europe/Moscow to equivalent datetime in india.

Europe/Moscow undergoes DST on March 30th 2008 at 2am.
So When i feed this time, iam getting this exception

"Exception in thread "main" java.lang.IllegalArgumentException: Illegal instant due to time zone offset transition: 2008-03-29T23:00:00.000" ...

if i give any datetime other than this, conversion is fine.

here goes my code...

DateTimeZone fromZone = DateTimeZone.forID("Europe/Moscow"); DateTimeZone toZone = DateTimeZone.forID("Asia/Calcutta");
//yyyy mm dd hh mm ss ms
DateTime dt = new DateTime(2008, 03, 30, 02, 0, 0, 0, fromZone);
System.out.println(dt.toDateTime(toZone));


Please help me in finding a solution.
Thanks in advance.

hi all

iam working on timezone conversion. when source and destination timezones dont fall under DST my conversion function is working fine. But when any timezone is under DST, conversion is not appropriate.iam using jdk1.5.0_01 and jre1.5.0_01. i also have tzupdater.jar in my classpath

Iam trying to convert 1/10/2007 in Pacific/Auckland to equivalent time in Africa/Casablanca.

here goes my code...
{
TimeZone tz1=TimeZone.getTimeZone("Pacific/Auckland");
int fromDST=tz1.getDSTSavings();
TimeZone tz2=TimeZone.getTimeZone("Africa/Casablanca");
int toDST=tz2.getDSTSavings();
Calendar cal=Calendar.getInstance();
cal.set(Calendar.YEAR,2007);
cal.set(Calendar.MONTH,9);
cal.set(Calendar.DATE,1);
cal.set(Calendar.HOUR_OF_DAY,HtmlHelper.getHourValueInt
(Integer.parseInt("12"),"AM")); //getHourValueInt - method that
gives hour value in terms of AM PM
cal.set(Calendar.MINUTE,0);
convertLocalToLocalWithDST(new Timestamp(cal.getTime().getTime())
,tz1,fromDST,tz2,toDST));
}

public static Timestamp convertLocalToLocalWithDST(Timestamp timestamp, TimeZone fromZone,int fromDST, TimeZone toZone,int toDST) {

return convertGmtToLocalWithDST(convertLocalToGmtWithDST(timestamp, fromZone,fromDST), toZone,toDST);
}


public static Timestamp convertLocalToGmtWithDST(Timestamp timestamp, TimeZone localZone,int fromDST) {
Timestamp newTimestamp = null;
if (timestamp != null) {
Calendar calendar = new GregorianCalendar(localZone);
calendar.setTime(timestamp);
calendar.set(Calendar.DST_OFFSET,fromDST);
int zoneOffset = calendar.get(Calendar.ZONE_OFFSET);

if(localZone.inDaylightTime(timestamp)){
newTimestamp = new Timestamp(calendar.getTime().getTime() - zoneOffset - fromDST);
}else{
newTimestamp = new Timestamp(calendar.getTime().getTime() - zoneOffset + fromDST);
}

}
return newTimestamp;
}


public static Timestamp convertGmtToLocalWithDST(Timestamp timestamp, TimeZone localZone,int toDST) {
Timestamp newTimestamp = null;
if (timestamp != null) {
Calendar calendar = new GregorianCalendar(localZone);
calendar.setTime(timestamp);
calendar.set(Calendar.DST_OFFSET,toDST);
int zoneOffset = calendar.get(Calendar.ZONE_OFFSET);

if(localZone.inDaylightTime(timestamp)){
newTimestamp = new Timestamp(calendar.getTime().getTime() + zoneOffset + toDST );
}
else{
newTimestamp = new Timestamp(calendar.getTime().getTime() + zoneOffset + toDST +toDST );
}
}
return newTimestamp;
}

converted time should be 30 Sep 2007 11am but iam getting 30 Sep 2007 12am

can anybody please help me out
