Save xsd:dateTime in java.util.Date

Hi,
can anybody give me a code snippet to save a String representing an xsd:dateTime (probably containing timezone information) to java.util.Date?
I really don't know how to do it.
Thanks,
Sven

In general if you have a String that contains a formatted date, and you want to make a Date object out of that, then you use a java.text.SimpleDateFormat object and its parse() method.

Error while deploying a web service whose return type is java.util.Date

Hi
I have written a simple web service which takes in a date input (java.util.Date) and returns the same date back to the client.
public interface Ping extends Remote
* A simple method that pings the server to test the webservice.
* It sends a datetime to the server which returns the datetime.
* @param pingDateRequest A datetime sent to the server
* @returns The original datetime
public Date ping(Date pingDateRequest) throws RemoteException;
The generation of the Web service related files goes smoothly in JDeveloper 10g. The problem arises when I try to deploy this web service on the Oracle 10g (10.0.3) OC4J standalone. it gives me the following error on the OC4J console :
E:\Oracle\oc4j1003\j2ee\home\application-deployments\Sachin-TradingEngineWS-WS\
WebServices\com\sachin\tradeengine\ws\Ping_Tie.java:57: ping(java.util.Date) in com.sachin.tradeengine.ws.Ping cannot be applied to (java.util.Calendar) _result = ((com.sachin.tradeengine.ws.Ping) getTarget()).ping

I read somewhere that the conversion between java to xml datatype and vice versa fails for java.util.Date, so it is better to use java.util.Calendar. When I change the code to return a java.util.Calendar then the JDeveloper prompts me the following failure:
Method Ping: the following parameter types do not have an XML Schema mapping and/or serializer specified : java.util.Calendar.
This forces me to return a String data.
I would appreciate if someone can help me out.

Hi
I got the web service working with some work around. But I am not sure it this approach would be right and good.
I started altogether afresh. I did the following step :
1. Created an Interface (Ping.java) for use in web Service as follows :
public interface Ping extends Remote{
public java.util.Date ping(java.util.Date pingDateRequest)
throws RemoteException;
2. Implemented the above interface in PingImpl.java as follows :
public class PingImpl implements Ping
public java.util.Date ping(java.util.Date pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
3. Compiled the above 2 java files.
4. Generated a Stateless Java Web Service with the help of JDeveloper. This time the generation was sucessful.(If I had "java.util.Calendar" in place of "java.util.Date" in the java code of the above mentioned files the web service generation would prompt me for error)
5. After the generation of Web Service, I made modification to the Ping interface and its implementing class. In both the files I replaced "java.util.Date" with "java.util.Calendar". The modified java will look as follows :
Ping.Java
=========
public interface Ping extends Remote{
public java.util.Calendar ping(java.util.Calendar pingDateRequest)
throws RemoteException;
PingImpl.Java
================
public class PingImpl implements Ping
public java.util.Calendar ping(java.util.Calendar pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
6. Now I recompile both the java files.
7. Withour regenerating the Web Service I deploy the Web Service on OC4j 10.0.3 from JDeveloper. This time the deployment was sucessful.(The Deployment fails if I don't follow the step 5.)
8. Now I generated a Stub from JDeveloper and accessed the stub from a client. It works fine. Here if you see the Stub code it takes java.util.Date as a parameter and returns a java.util.Date. (Mind you I am accepting a java.util.Calendar and returning the same in my Web Service interface. Step 5)
The confusing thing is the Serialization and Deserialization of Data from Client java data to Soap message and Soap message to Server java data.
From Client to SOAP :
java.util.Date to datetime
From SOAP to Server :
datetime to java.util.Calendar
From Server to SOAP :
java.util.Calendar to datetime
From SOAP to Client :
datetime to java.util.Date (I am not able to understand this part of the conversion)
Any help or inputs would be appreciated.
Thanks

Java.sql.Date vs java.util.Date vs. java.util.Calendar

All I want to do is create a java.sql.Date subclass which has the Date(String) constructor, some checks for values and a few other additional methods and that avoids deprecation warnings/errors.
I am trying to write a wrapper for the java.sql.Date class that would allow a user to create a Date object using the methods:
Date date1 = new Date(2003, 10, 7);ORDate date2 = new Date("2003-10-07");I am creating classes that mimic MySQL (and eventually other databases) column types in order to allow for data checking since MySQL does not force checks or throw errors as, say, Oracle can be set up to do. All the types EXCEPT the Date, Datetime, Timestamp and Time types for MySQL map nicely to and from java.sql.* objects through wrappers of one sort or another.
Unfortunately, java.sql.Date, java.sql.Timestamp, java.sql.Time are not so friendly and very confusing.
One of my problems is that new java.sql.Date(int,int,int); and new java.util.Date(int,int,int); are both deprecated, so if I use them, I get deprecation warnings (errors) on compile.
Example:
public class Date extends java.sql.Date implements RangedColumn {
public static final String RANGE = "FROM '1000-01-01' to '8099-12-31'";
public static final String TYPE = "DATE";
   * Minimum date allowed by <strong>MySQL</strong>. NOTE: This is a MySQL
   * limitation. Java allows dates from '0000-01-01' while MySQL only supports
   * dates from '1000-01-01'.
public static final Date MIN_DATE = new Date(1000 + 1900,1,1);
   * Maximum date allowed by <strong>Java</strong>. NOTE: This is a Java limitation, not a MySQL
   * limitation. MySQL allows dates up to '9999-12-31' while Java only supports
   * dates to '8099-12-31'.
public static final Date MAX_DATE = new Date(8099 + 1900,12,31);
protected int _precision = 0;
private java.sql.Date _date = null;
public Date(int year, int month, int date) {
    // Deprecated, so I get deprecation warnings from the next line:
    super(year,month,date);
    if(! isWithinRange(this))
      throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public Date(String s) {
    super(0l);
    // Start Cut-and-paste from java.sql.Date.valueOf(String s)
    int year;
    int month;
    int day;
    int firstDash;
    int secondDash;
    if (s == null) throw new java.lang.IllegalArgumentException();
    firstDash = s.indexOf('-');
    secondDash = s.indexOf('-', firstDash+1);
    if ((firstDash > 0) & (secondDash > 0) & (secondDash < s.length()-1)) {
      year = Integer.parseInt(s.substring(0, firstDash)) - 1900;
      month = Integer.parseInt(s.substring(firstDash+1, secondDash)) - 1;
      day = Integer.parseInt(s.substring(secondDash+1));
    } else {
      throw new java.lang.IllegalArgumentException();
    // End Cut-and-paste from java.sql.Date.valueOf(String s)
    // Next three lines are deprecated, causing warnings.
    this.setYear(year);
    this.setMonth(month);
    this.setDate(day);
    if(! isWithinRange(this))
      throw new ValueOutOfRangeException((RangedColumn)this, "" + this);
public static boolean isWithinRange(Date date) {
    if(date.before(MIN_DATE))
      return false;
    if(date.after(MAX_DATE))
      return false;
    return true;
public String getRange() { return RANGE; }
public int getPrecision() { return _precision; }
public String getType() { return TYPE; }
}This works well, but it's deprecated. I don't see how I can use a java.util.Calendar object in stead without either essentially re-writing java.sql.Date almost entirely or losing the ability to be able to use java.sql.PreparedStatement.get[set]Date(int pos, java.sql.Date date);
So at this point, I am at a loss.
The deprecation documentation for constructor new Date(int,int,int)says "instead use the constructor Date(long date)", which I can't do unless I do a bunch of expensive String -> [Calendar/Date] -> Milliseconds conversions, and then I can't use "super()", so I'm back to re-writing the class again.
I can't use setters like java.sql.Date.setYear(int) or java.util.setMonth(int) because they are deprecated too: "replaced by Calendar.set(Calendar.DAY_OF_MONTH, int date)". Well GREAT, I can't go from a Date object to a Calendar object, so how am I supposed to use the "Calendar.set(...)" method!?!? From where I'm sitting, this whole Date deprecation thing seems like a step backward not forward, especially in the java.sql.* realm.
To prove my point, the non-deprecated method java.sql.Date.valueOf(String) USES the DEPRECATED constructor java.util.Date(int,int,int).
So, how do I create a java.sql.Date subclass which has the Date(String) constructor that avoids deprecation warnings/errors?
That's all I really want.
HELP!

I appreciate your help, but what I was hoping to accomplish was to have two constructors for my java.sql.Date subclass, one that took (int,int,int) and one that took ("yyyy-MM-dd"). From what I gather from your answers, you don't think it's possible. I would have to have a static instantiator method like:public static java.sql.Date createDate (int year, int month, int date) { ... } OR public static java.sql.Date createDate (String dateString) { ... }Is that correct?
If it is, I have to go back to the drawing board since it breaks my constructor paradigm for all of my 20 or so other MySQL column objects and, well, that's not acceptable, so I might just keep my deprecations for now.

Duration between 2 java.util.Dates

Hi,
Recently found a problem calculating duration between two dates. It has confused me as it happens only on certain dates!
Notice the duration for 28/10/07 - outputs 85 minutes. Am I missing something obvious here?
GregorianCalendar gc = new GregorianCalendar(2007,0,1);
        for(int i=0; i<365; i++) {
            String date = gc.get(Calendar.DATE) + "/" + (gc.get(Calendar.MONTH)+1) + "/" + gc.get(Calendar.YEAR);
            String dateVal1 = date + " 00:39";
            GregorianCalendar date1 = DateTime.toGregorianCalendar(dateVal1, "dd/MM/yy HH:mm");
            String dateVal2 = date + " 01:04";
            GregorianCalendar date2 = DateTime.toGregorianCalendar(dateVal2, "dd/MM/yy HH:mm");
            System.out.println(date + " - " + DateTime.calculateDuration(date1, date2));
            gc.add(Calendar.DATE, 1);
public final static GregorianCalendar toGregorianCalendar(String date, String pattern) {
        SimpleDateFormat formatter = new SimpleDateFormat(pattern);
        GregorianCalendar gc1 = new GregorianCalendar();
        Date parsedTime = new Date();
        try {
            parsedTime = formatter.parse(date);
        } catch (ParseException ex) {
            ex.printStackTrace();
            return null;
        gc1.setTime(parsedTime);
        return gc1;
public final static long calculateDuration(java.util.Date a, java.util.Date b) {
        Calendar earlier = Calendar.getInstance();
        Calendar later = Calendar.getInstance();
        if (a.compareTo(b) < 0) {
            earlier.setTime(a);
            later.setTime(b);
        else {
            earlier.setTime(b);
            later.setTime(a);
        System.out.println(earlier.getTimeInMillis() + ":" + later.getTimeInMillis());
        long l1 = earlier.getTimeInMillis();
        long l2 = later.getTimeInMillis();
        return (int)(((l2-l1)/1000) / 60);
}

I asked someone in the office and its the first thing they said!!!!!!!!!!!!!!!
So - now fixed and I know for next time.
Thanks - the dukes are yours

Discussion - Date/Time POJO property - String or java.util.Date

Hi,
I always wonder how date/time should be declared in POJOs - String or java.util.Date. I have used both and always felt comfortable with String but still would like to know your views. (In DB datatype is datetime).
I know some of you will say "as per requirement" but what I have experienced we never give too much thought and when we have issues down the line we start wondering.

I always wonder how date/time should be declared in POJOs - String or java.util.Date. I have used both and always felt comfortable with String but still would like to know your views.
(In DB datatype is datetime).If the latter is a given, then I would definitely use a Date. Doing the Date/String conversion at the DAO level seems an improper location; in particular, it constrains what upper layers can do with it:
- if the business logic has to do date/time computation, it will have to convert back to Date (or Joda DateTime)
- if the UI needs a different representation than the one that was used in the DAO (such as, different time zone, or showing only the month, whatever,...) it will probably need such a conversion too, and another one for the reformatting (or clumsy code parsing the date string).
I know some of you will say "as per requirement" but what I have experienced we never give too much thought and when we have issues down the line we start wondering.I can easily see the issues caused by premature conversion to String. But what kind of issues do you risk if you keep the Date representation?
In summary, I'm all in favor of using a Date (or Joda DateTime ) all along, until it's eventually displayed.
Regards,
J.

Why not Deprecate java.util.Date and java.util.Calendar

With the introduction of java.time, why did you not flag java.util.Date and java.util.Calendar. These classes have been a bane to every Java developer and should never be used again with the introduction of Java 1.8.

Adding the @Deprecated annotation would only just provide a warning about an old API and recommendation to the developer(s) to no longer use it. Doing so would not break any existing library out there; in fact quite a number of constructors and methods on the Date class have already been flagged deprecated.
The new java.time package is far superior to Date/Calendar.

How To Add Days into a Date from java.util.Date class

I have a problem when i wants to add 2 or days into a
date object geting by java.util.Date class. so please help me resolve this issue?
for e.g i have a date object having 30/06/2001,
by adding 2 days i want 02/07/2001 date object ?
Code
public class test2
public static void main(String args[])
java.util.Date postDate = new java.util.Date();
myNewDate = postDate /* ?*/;
Here i want to add 2 date into postDate

Use Calendar...
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
cal.add(Calendar.DAY, 2); // I'm not sure about that "DAY"

Hi Meera
This works fine in creator. I tested with a webservice having a method which returns java.util.date. I used the same code in that method to return java.util.Date. But the same method was returning a Calendar object instead of Date. So I added getTime() method to get the Date.
Can you post few lines of your code that you are writing in Creator.
Thanks

What's wrong with java.util.Date type?

Hi!
When I try to persist object having field of type java.util.Date I get the

I've created my own dictionary with dateToSQL() method overridden.
Now it works fine. But it's a kind of strange. Oracle is used often and my
JDBC drivers
are the most recent (at least, from the oracle.com).
Anyway, thank you again.

Patric,
Thank you for response.
We're using Oracle 8.1.7 via OCI driver from Oracle 9.2.
I've already tried 2.4.0 and it works fine there but I've found another
problem there
preventing me from using it. See my post in solarmetric.kodo.betanewsgroup.

That's odd -- what version of Oracle are you using?
Moving to Kodo JDO 2.4.0
(http://www.solarmetric.com/Software/beta/2.4.0) will almost certainly
get rid of this problem, as we use exclusively prepared statements in
it, and therefore pass dates etc. to JDBC as parameters.
But, to get things working with your Oracle database and Kodo JDO 2.3,
you could create your own extension of OracleDictionary and override the
dateToSQL() method to generate the appropriate TO_DATE() syntax. See our
documentation for more details on creating custom database dictionaries.

But when I try to execute the statement above against the database
manually
everything works fine.
I'm absolutely desperate!
P.S. On 2.4.0 RC the operation invoking this database insert completes
fine.

Hi!
When I try to persist object having field of type java.util.Date I
get
the
following SQL logged by Kodo with subsequent transaction rollback:

When I change "{ts '2002-11-14 15:03:35.059'}" with
"TO_DATE('2002-11-14
15:03', 'YYYY-DD-MM HH24:MI')" in SQL editor
and execute it everything works fine.
What does "{ts '..'}" mean? Is it a SQL generation error?
Thank you in advance.

What's wrong with java.util.Date??

Hi all,
I was just practicing a bit of java.util ,when i was compiling my code-
import java.util.Date;
import java.text.SimpleDateFormat;
class DateStamp{
public static void Main(String args[]){
doDate1;
String D;
int D1,D2,D3;
Date dt=new Date();
SimpleDateFormat sdf=new SimpleDateFormat("dd-mm-yyyy");
/*When using method .setDate(x) ,is x an integer or String?can x=2/5/2002 or 2-5-2002?*/
public void doDate1{
dt.setDay(12);
dt.setMonth(12);
dt.setYear(102);
D=dt.getTime();
D.parseInt(D1);D=""
D=sdf.getTime();
D.parseInt(D2);
int D3=D2-D1;
int D3=D3/86400000;/*How do you convert milisec-to-days?*/
D=D3.toString().
System.out.println(D+"days have elapsed since then");
the compiler said this-
File Compiled...
--------------------------- Javac Output ---------------------------
DateStamp.java:7: Invalid expression statement.doDate1;^DateStamp.java:14: Instance variables can't be void: doDate1public void doDate1; ^2 errors
this problem is persistant, and i'm a java newbie ,Does anyone know what's wrong here?
Thanks!

How do you get System date onto a Date variable?Calendar.getInstance().getTime() returns a java.util.Date for the current time. You can also use System.currentTimeMillis() and turn it into a Date.
Will date.after(Date when) method work when Date
variables are in milisecs?Date.after(Date when) compares two date objects. As the JavaDoc says "Returns:
true if and only if the instant represented by this Date object is strictly later than the instant represented by when" To me that says that milliseconds are taken into account, I.E. comparing dates actually compares the date plus the time portion.
>
What methods-
*Convert a date(dd/mm/yy) to milisec?If you look in the javaDoc you'll see "long getTime() Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object." Calendar also has the getTimeInMillis() method.
*Convert a milisec value to a date(dd/mm/yy)?Calendar.setTimeInMillis(long);
I'm have this little problem.
When using GregorianCalander-
*need to initialize?
*need set today's date?Calendar.getInstance() will return an appropriate Calendar object for the current locale initialized to the current date/time.
*how do you check if a date exceeds 3 weeks?I'm not sure what you mean. There are a couple of roll(...) methods that will allow you to add a unit of time to a date. I.E. you could add three weeks to a date.
To ignore the time portion of a date just set the time to "00:00"

How can i compare: java.util.Date oracle.jbo.domain.Date?

I have made a ViewObject wich contains a date column.
I want to check if this date is smaller/greater than sysdate:
i get following error:
Error(45,24): method <(java.util.Date, oracle.jbo.domain.Date) not found in class Class4
code:
SimpleTimeZone pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, ids[0]);
// set up rules for daylight savings time
pdt.setStartRule(Calendar.APRIL, 1, Calendar.SUNDAY, 2 * 60 * 60 * 1000);
pdt.setEndRule(Calendar.OCTOBER, -1, Calendar.SUNDAY, 2 * 60 * 60 * 1000);
// create a GregorianCalendar with the Pacific Daylight time zone
// and the current date and time
Calendar calendar = new GregorianCalendar(pdt);
Date trialTime = new Date();
calendar.setTime(trialTime);
(VO_ULNRow)singleRow = null;
while(vo.hasNext()){ // ViewObject vo;
singleRow = (VO_ULNRow)vo.next();
if(calendar.getTime() < singleRow.getEO_ULN_BORROWFROM()); //singleRow returns oracle.jbo.domain.Date
etcetera
how can i compare those 2?

Hi,
oracle.jbo.domain.Date has two methods which suit your needs
longValue() which returns a long (though I'm not sure if returns a long comparable to the long returned by java.util.Date)
and dateValue() which returns a java.util.Date
I hope it helps,
Giovanni

i get following error:

oracle.jbo.domain.Date) not found in class Class4
if(calendar.getTime() <
singleRow.getEO_ULN_BORROWFROM()); //singleRow returns
oracle.jbo.domain.Date
how can i compare those 2? You cannot compare these two values directly. You must convert the oracle.jbo.domain.Date object to a GregorianCalendar object. Something like:
oracle.jbo.domain.Date dt = singleRow.getEO_ULN_BORROWFROM();
GregorianCalendar gc = new GregorianCalendar(dt.getYear(), dt.getMonth(), dt.getDay());
if (calendar.getTime() < gc.getTime())
}

I can't cast java.util.Date to oracle.jbo.domain.Date

Hi, i have a variable "pippo" type java.util.Date formatted like (dd-MM-YYYY hh:mm:ss)
and I want insert in my Database where the field is Date type(oracle.jbo.domain.Date)
in the same format(dd-MM-YYYY hh:mm:ss).
I try to convert "pippo" but the result is formatted(dd-MM-YYYY hh:mm:ss).
Thank's a lot yours time and i'm very sorry for my easy english
Bye Luca

Here is what i have seen that works , but does not preserve milliseconds. Does anyone have other solution? Using dateValue() looses hours, mins and seconds.
public oracle.jbo.domain.Date toJboDate(java.util.Date pJavaDate)
return new oracle.jbo.domain.Date(new Timestamp(pJavaDate.getTime()));
public java.util.Date toJavaDate(oracle.jbo.domain.Date pJboDate)
return new Date(pJboDate.timestampValue().getTime());

Save xsd:dateTime in java.util.Date
