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
following SQL logged by Kodo with subsequent transaction rollback:
2002-11-14 15:03:35,099 INFO

'1',
{ts '2002-11-14 15:03:35.059'}, 147)
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.

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.

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"

Getting error by ValueBinding with java.util.Date

Hi.
1. my english is not so good.
I develop a JSF-application to learn more about JSF-technologie.
I use Eclipse 3.2
Plugins: Web Tools Platform (WTP), Web Standard Tools, Java Server Faces // Version 1.5.0
JRE: 1.5
java-impl.jar and java-api.jar (sun)
Look at this JSP-File Code
<h:inputText id="dbirth" value="#{dataBean.dbrith}"> </h:inputText>
this produce an error: EL expression does not evaluate to expected types for this attribute
dataBean is a ManagedBeain. So if I use any athor variable from this Bean like:
<h:inputText id="sname" value="#{dataBean.sname}"> </h:inputText>
is going well. But if I use any java.util.Date variable it produce the error.
I tried with other Bean and the error is still there.
I can compile and use this JSP, but this error is there.
Have any one an idea what is happen there??
I looked at Eclipse forums, but I didnt found description for an error like this..
thanks for any help...

The problem is because you have bound the inputText to a java.util.Date object, instead of a String. You must use Strings with inputText. However, JSF has provided a way for you to convert objects into a String. It just needs to know how to do that. Luckily for you, there is a converter already available to convert a Date object into a String. Converters will also take input Strings and convert them into an object.
So, in your case, use the convertDateTime tag. Like this:
<h:inputText id="dbirth" value=#{dataBean.dbrith}">
<f:convertDateTime type="date" pattern="MMM dd, yyyy" />
</h:outputText>Try it. You may change the pattern to whichever valid one you like.

What's wrong with my mobile data network?

I've had this 2nd hand iPhone 4 for almost 2 months and everything has been working perfectly until today. I was using viber and sending messages to my friends and it suddenly stopped working and i have no idea why, i thought i just lost my 3G for a while so i waited a few hours for it to come back up, this started around 3pm and it's 12am right now and it's still not working... Everything else worked such as skype, twitter and the internet but for some reason i couldnt send and receive messages on viber and imessage. I also didn't get any notifications from ANYTHING during the whole time until i connected to my wi-fi at home which i then got flooded with messages, tweets and etc.
I think that theres something wrong with my mobile data network and i dont really know what it is since everything was working fine this afternoon and it just suddenly stopped? Connecting to Wi-fi makes everything work fine and i actually receive notifications and am able to send and receive messages to my friends on viber and imessage.
Can anyone help me?
My carrier is CSL and it has unlimited data if anyone n

I havent contacted my carrier and i really dont think they will be able to help since i go to them every month to pay my phone bill and they can barely speak english...
I've turned my phone on and off 3 times and ive also reseted my network settings

What's wrong with Java readline()?

I just updated to OS X 10.6.8 and installed the Java update 1.6.0_26-b03-384.
It appears that BufferedReader.readLine() is broken for reading input lines from the console. readLine() does not terminate with a newline.
This is pretty basic. What's up?
import java.io.*;
          This class demonstrates how to read a line of text from the keyboard
class ReadLine{
          public static void main(String[] args) throws IOException{
                    String CurLine = ""; // Line read from standard in
                    System.out.println("Enter a line of text (type 'quit' to exit): ");
                    InputStreamReader converter = new InputStreamReader(System.in);
                    BufferedReader in = new BufferedReader(converter);
                    while (!(CurLine.equals("quit"))){
                              CurLine = in.readLine();
                              if (!(CurLine.equals("quit"))){
                                        System.out.println("You typed: " + CurLine);

As it turns out, there's nothing wrong with ReadLine(), the problem was Ant 1.8.2.
http://issues.apache.org/bugzilla/show_bug.cgi?id=50960
The Apache distribution is dated late 2010. The Apple version of 1.8.2 states that it was compiled on June 3, 2011, but if Apple built from the distribution and not from the corrected svn trunk that would explain it.
My work-around was to install and link ant 1.8.1.

What Is Wrong With Java? STILL NOT ANSWERED, PLEASE ANSWER!

So today (10 PM January 20th), the Firefox Plugin Checker said that my Java version was outdated. I also got a pop-up saying that my current version of Java at the time (Java 7 update 10) had vulnerabilities. So to try and fix this, I went to the Java page and downloaded the update (Java 7 update 11).
To check and see if my update was working, I went to Java's check page, as well as another page I use. And here I discovered a problem. I got a notification that an old version of Java had been detected, and another prompt to download the current version (which I had already done). So I erased all versions of Java from my control panel, and tried to check it again. And when I did, I got this: http://oi50.tinypic.com/35b6xx2.jpg and http://oi47.tinypic.com/15fg37p.jpg.
As you can see, both pages tell me that I need to install a missing plugin of some sort. So, thinking this would resolve the issue, I clicked the Install Missing Plugin button. This is what it told me was missing: http://oi45.tinypic.com/302uwbl.jpg. So I clicked next to install it.... and got this: http://oi45.tinypic.com/2cici0x.jpg, which I assume means that the plugin did not install. So I pressed Manual Install... and was lead/linked right back to the Java download page (where it all began, and what doesn't seem to be working in the first place)
I go to check my plugins again (Just to make sure and also for extra information), and it appears to say that my Java version is current (is that what "Java Deployment Toolkit 7.0.110.21" is? I don't know, I am not good at technology at all. Either way, here is what it looks like: http://oi48.tinypic.com/4kxzz4.jpg). So...if it is current, why is it not working (i.e. I am unable to play games, DO MY COLLEGE CLASSWORK, or play Java-based games)?
If it helps anything, here is what my control panel looks like in regards to Java right now: http://oi45.tinypic.com/2qlxu9t.jpg Am I missing anything that would make Java work?
And before anyone says that Java is not essential: It may be that way to you, but I need Java to do classwork for college. Veterinary college.
So, in short, what is going on with Java, and how can I fix it?
EDITEDITEDIT: I Have found that I can do my classwork without Java.
HOWEVER, this DOES NOT mean that the problem is solved or over with. I STILL WANT TO KNOW HOW TO FIX THIS PROBLEM AND GET JAVA TO WORK. Even if I never actually need it, I would still like to have a (working!!!) Java version because of two reasons: 1) I would rather have such a program and not need it, than need such a program and not have it, and 2) aesthetics. Sorry to say, but I am very particular about how things look when it comes to my belongings, and the fact that Java is messing up is making me actually stressed. In short, I still want the above issue solved, even if it's just purely for the sake of Peace Of Mind.

STILL HAVE NOT GOTTEN A REPLY. PLEASE ANSWER ASAP, AS THIS IS STILL IMPORTANT TO ME. COME ON NOW, I KNOW THAT THERE ARE PEOPLE ONLINE AND ANSWERING QUESTIONS!!

How to use JtextFild with java.util.Date;

hi
My problem is that i have a date data type field inaccess in table.
Otherside i use JTextField.
First when this window show i initialize this field with current date.
The code for this is
lbdate = new JLabel("User Date",JLabel.RIGHT);
          lbdate.setBorder(new EtchedBorder());
          txtdate = new JTextField();
          txtdate.setBorder(BorderFactory.createLineBorder(Color.red));
          //month convert into string
          int m = cal.get(Calendar.MONTH);
          m++;
          String mon = Integer.toString(m);
          //day convert into string
          int d = cal.get(Calendar.DATE);
          String date = Integer.toString(d);
          //year convert into string
          int y = cal.get(Calendar.YEAR);
          String year = Integer.toString(y);
          txtdate.setText(mon+" / "+date+" / "+year);
i am not satisfied by this. How can initialize the JtextField by some other method.
The secound part of question is that how to reterive the date data type of field and see in the textfield.I see butt it returns like this year/month/date(this date is coming from database which already input) 00:00:00
How can i discard 00:00:00(this time)
I code for this is
Date date = rs.Date();
txtfld.setText(date); //Here error is occured of TypeCasting
and tell me that how date type object can convert into String for set the text of field
because JTextField only accept the String data.
(if u illestrate with code).
thanks

What's wrong with 8.1.7 export utility

I was trying to export an Oracle 8.1.6 database by using export
utility from Oracle 8.1.7 client. But I get a lot of errors.
When I try to export from Oracle 8.1.6 client everything goes
smoothly.
What's wrong with export utility in Oracle 8.1.7 client??
regards,
Evan

It is because for each new version there is more and different
things that need to be exported so the x+1 exp utility expects
the new things to be there and fails if they are not.
The reason I suspect Oracle did this is that most exports are
done on the server. It is not generaly a good idea to run exp
across a network for performance reasons (ie you move the entire
database). As most exports are done on the server the
comapability is not an issue.most bullet proof solution.

Java.util.Date badly serialized to java.sql.Timestamp Coherence 3.5.2

Hi all,
I'm running into this odd behaviour.
I serialize java.util.Date objects to cache and when I read them back from cache, they appear to be java.sql.Timestamp types.
I've isolated a junit test for that.
Do you know why Coherence changes the type in the middle?
Regards
Harry.

I'm trying to add the system date with a Label. What is wrong with the code

import java.util.*;
import javax.swing.*;
public class CurrentDateApplet extends JApplet
     Calendar currentCalendar = Calendar.getInstance();
     JLabel dateLabel = new JLabel();
     JPanel mainPanel = new JPanel();
     int dayInteger = currentCalendar.get(Calendar.DATE);
     int monthInteger = currentCalendar.get(Calendar.MONTH)+1;
     int yearInteger = currentCalendar.get(Calendar.YEAR);
     public void init()
          mainPanel.add(dateLabel);
          setContentPane(mainPanel);
          dateLabel.append(currentCalendar.get(Calendar.HOUR) + currentCalendar.get
                    (Calendar.MINUTE);
}

As for what's wrong with the code, it would be easier if you said: it doesn't show the date (it does this instead), it doesn't compile (I get this message) etc.
Anyway I'll assume you want to display the time in a label...
dateLabel.append(currentCalendar.get(Calendar.HOUR) + currentCalendar.get
(Calendar.MINUTE);This won't compile: the parentheses are mismatched, and there is simply no such thing as append(). So we could trydateLabel.setText("" + currentCalendar.get(Calendar.HOUR) + currentCalendar.get(Calendar.MINUTE));This wroks, but looks pretty nasty and it's not how you are supposed to format dates and times. Here's the unofficial party line, nicked from one of jverd's posts:
Calculating Java dates: Take the time to learn how to create and use dates
Formatting a Date Using a Custom Format
Parsing a Date Using a Custom Format
From those links you should be able to find those applicable to times like this: http://www.exampledepot.com/egs/java.text/FormatTime.html
Using this approach you would end up with something like:import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.swing.JApplet;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class CurrentDateApplet extends JApplet
    private Date date;
    private JLabel timeLabel;
    private JPanel mainPanel;
    public void init()
        mainPanel = new JPanel();
        timeLabel = new JLabel();
        mainPanel.add(timeLabel);
        setContentPane(mainPanel);
        date = new Date();
        Format formatter = new SimpleDateFormat("HH:ss a");
        timeLabel.setText(formatter.format(date));
}

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 :

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:

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.

What's wrong with my code for comparing date retreived from db and sysdate?

Hi all,
I need to retrive date from the DB and compare it to system date.i have posted the code below.i get java.sql.SQL Exception:Io exception:Socket closed.
What's wrong with the code?please help me.Thanks in advance.
public boolean date() throws IOException, SQLException {
Connection con1;
long millis = System.currentTimeMillis();
Timestamp timestamp = new java.sql.Timestamp(millis);
ResultSet rs4 = null;
try
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection(
"jdbc:oracle:thin:@abc:1605:xyz",
"cdf", "cdf");
Statement stmt_exp = con.createStatement();
rs4 = stmt_exp.executeQuery("SELECT DATE FROM TABLE_NAME")
while (rs4.next()) {
Timestamp timestamp2 = rs4.getTimestamp("expire_date");
con1.close();
catch (Exception e)
e.printStackTrace();
finally
//ResultSet rs4 = null;
//Timestamp timestamp2;
Timestamp timestamp2 = rs4.getTimestamp("expire_date");
if (timestamp2.compareTo(timestamp) < 0) //sysdate < exp date
return true;
} else {
return false;
}

Didn't you understand what BalusC said? You're closing the connection and then trying to use the ResultSet. The ResultSet will be closed when you close the connection so you can't use it anymore.
You should close the connection last thing in your code, probably in a finally. And after you close your ResultSet and Statement.
