Problems with DateFormat

All,
I am using a DateFormat to format TimeStamps to useful strings. I am getting some rather unexpected results in the form of extra leading zeros.
For example,
1) 03/07/2002 14:0043:51PM
2) 03/07/2002 0014:43:51PM
3) 0003/07/2002 14:0043:51PM
4) 03/0007/2002 14:43:51PM
Any ideas?

I have seen reports about the DateFormat class giving erroneous results when it's used to create TimeStamps for log files, this could be a bug -- you might want to check the bug database to see if it's been fixed and at what revision number when it was fixed. In the meantime, you might want to format the date yourself with something like this (it might even be faster)
import java.util.*;
class DateFormat {
   static Calendar c=Calendar.getInstance(TimeZone.getDefault(),Locale.getDefault());
   public static String Now () {
      c.setTime(new Date(System.currentTimeMillis()));
      int hour=c.get(Calendar.HOUR_OF_DAY);
      String AMPM=" AM";
      if (hour>11) AMPM=" PM";
      return i2s(c.get(Calendar.MONTH),2) + "/"+
             i2s(c.get(Calendar.DATE),2) + "/"+
             i2s(c.get(Calendar.YEAR),4) + " "+
             i2s(hour,2) + ":"+
             i2s(c.get(Calendar.MINUTE),2) + ":"+
             i2s(c.get(Calendar.SECOND),2)+AMPM;
   private static String i2s(int in, int len) {
      String tmp=""+in;
      if (tmp.length()>len) return tmp.substring(tmp.length()-len);
      while (tmp.length()<len) tmp="0"+tmp;
      return tmp;
   public static void main(String[] args) {
      System.out.println(Now());
}V.V.

  • Problem with DateFormat.parse

    hi,
    I'm working using Java 1.5.
    i'm using SimpleDateFormat to parse date strings. My program has the following piece of code:
    Class DateConverter {
    SimpleDateFormat m_sdate = null ;
    public DateConverter() {
    this.m_sdate = new SimpleDateFormat("yyyyMMdd") ;
    public Date to_date(String dstr) {
    return this.m_sdate.parse(dstr) ;
    The date parsing works fine as long as I give dates upto "00010101" but throws java.text.ParseException for the value "00001231". I was just eager to know whether 00010101 is the least date that can be parsed???
    Thanks,
    Venkatesh

    I don't get a ParseException with your code; if there is an earliest date that can be parsed it's not 1/1/1.fmt = new SimpleDateFormat("yyyy/MM/dd");
    new SimpleDateFormat("dd.MM.y G").format(fmt.parse("0/12/31"));
    output: <31.12.01 BC>

  • Problem with date pattern

    Hi all,
    I have a little maddening problem with oracle.jbo.domain.Date.
    I have a viewObject with an attribute (fechaCompra) type Date and I need the time too so in controlHints I have defined:
    format type: Simple Date
    Format: yyyy-MM-dd 'at' hh:mm:ss
    Right, on runTime now i see ok the data and in the inputDate appears the calendar and the hour .
    But when I take the value of this attribute, to call a void that takes a oracle.jbo.domain.Date type, raises an error when parses the value of the atribute.
    All this doesn't happen when in the view object the controlHints are defined like this:
    format type: Simple Date
    Format: yyyy-MM-dd
    Any idea?
    Thanks in advance,
    Rowan

    hello,
    My guess would be that when you drop your formatted date into the methode the parse function is called from String to date, this work with no time attached.
    But fails with the time attached. I would double check the specific class you pass to each method to be sure they are correct.
    hat you mention parse gives an even bigger hint that you are using the parse function from oracle.jbo.domain.Date, which takes a string.
    This function will fail with your custom patterns.
    //get the value
    String value = .....
    //Not 100% sure if the at needs to be escaped or not
    DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd at hh:mm:ss");
    //Prolly needs a try catch, writing this by hand
    java.util.Date utilDate = sdf.parse(value);
    java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());
    oracle.jbo.domain.Date jboDate = new oracle.jbo.domain.Date(sqlDate);
    //pass to your method-Anton

  • Problem with setting Source Level in Sun Studio 2

    I've got problem with setting Source Level to 1.5 in Sun Studio 2. When I try to set it to 1.5 in Project properties and click Ok everything seem to go well, but when I open Project Properties again Source Level is set to 1.4. I need this to work cause I started to lear Java recently and I want to use foreach loop.
    Please help

    I'm just citing an example using Date().
    In fact, whether I use DateFormat or Calendar, it shows the same result.
    When I set the date to 1 Jan 1950 0 hours 0 minutes 0 seconds,
    jdk1.4.2 will always return me 1 Jan 1950 0 hours 10 minutes 0 seconds.
    It works correctly under jdk1.3.1

  • Date problem with IST(+5:30) timezone

    Hi,
    I'm having problem with Timezone IST, which is GMT + 05:30.
    SimpleDateFormat returns incorrect date when timezone on client machine is other than IST.
    When Timezone on machine is IST, correct value is returned.
    See the below example. All four dates are same ( LKT is also + 05:30).
    When timezone on machine is IST, all four dates are displayed same.
    For any other timezone, IST date is displayed incorrectly, rest 3 are displayed correctly.

    IS this a bug in java??
    Regards

    Your program is in error. PDT and LKT are not valid time zone ids in Java. There may be other problems, also, I didn't check.
    I know this program produces valid results, you can try it
    import java.text.DateFormat;
    import java.util.Date;
    import java.util.TimeZone;
    public class DateTest
        public static void main(String[] args)
            Date current = new Date();
            DateFormat df =
                DateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.FULL);
            System.out.println("Default TZ: " + df.format(current));
            df.setTimeZone(TimeZone.getTimeZone("IST"));
            System.out.println(df.format(current));
            df.setTimeZone(TimeZone.getTimeZone("GMT"));
            System.out.println(df.format(current));
            df.setTimeZone(TimeZone.getTimeZone("Etc/GMT-5"));
            System.out.println(df.format(current));
    }This program lists all of Java's time zones
    import java.util.*;
    public class TimezoneList
        public static void main(String[] args)
            int msPerHr = 3600 * 1000;
            String[] ids = TimeZone.getAvailableIDs();
            for (int n = 0; n < ids.length; n++)
                TimeZone tz = TimeZone.getTimeZone(ids[n]);
                System.out.print(
                    "TZ: " + ids[n] + "  " + (double) tz.getRawOffset() / msPerHr + "  ");
                System.out.println(
                    tz.useDaylightTime() ? "DST=" + (double) tz.getDSTSavings() / msPerHr : "");

  • Problem with af:selectInputDate (no calendar popup)

    Hi All,
    I have a problem with the af:selectInputDate component and the calendar popup when using a custom converter. My converter converts the date in a way, that it always has a four digit year depending on the short date format and the corresponding locale, e.g. 01/18/2007 instead of 01/18/07 for en-us. It looks like when I am using my converter with the component in the following way some javascript is not generated by the af:selectInputDate which results in an javascript error when clicking on the popup button:
    <h:panelGroup>
    <af:selectInputDate id="idPatientBirthDate" columns="12" simple="true" value="#{PatientDetails.patient.birthDate}">
    <f:converter converterId="BirthdateConverter" />
    </af:selectInputDate>
    <h:message for="idPatientBirthDate" errorClass="errorMessageStyle"></h:message>     
    </h:panelGroup>
    The following javascript is not generated using the above jsf:
    <script>
    if(window['_dfs'] == (void 0)){var _dfs=new Object();}_dfs["_id43:general:idPatientBirthDate"]='M/d/yyyy';function __id43Validator(){return true;}
    </script>
    I am using version 10.1.3.0.4 of ADF faces.
    My BirthdateConverter is a standard converter that implements the Converter interface and is not doing any magical. It works perfectly for other components. An interesting fact is, that the above javascript gets generated when I am using no converter at all or the standard date/time converters like f:convertDateTime provided by the RI. However, these don't provide the functionality I need.
    I have the bad feeling, that I am missing something. Does anyone else ran across this problem?
    Thanks,
    Herbert

    Frank,
    Thank you for your answer. I'm not using ADF BC, so is there a possible workaround? My model provides a standard java.util.Date. My converter looks like:
    public class BirthdateConverter implements Converter {
      public Object getAsObject(FacesContext facesContext, UIComponent uIComponent, String sDate) {
        Locale locale = facesContext.getCurrentInstance().getExternalContext().getRequestLocale();
        String pattern = AppUtil.getFourDigitYearPattern(DateFormat.SHORT);
        SimpleDateFormat sdf = new SimpleDateFormat(pattern, locale);
        java.util.Date d = sdf.parse(sDate);
        // converter logic
        return d;
      public String getAsString(FacesContext facesContext, UIComponent uIComponent, Object object) {
        if (object == null)
          return null;
        if (!(object instanceof Date))
          return object.toString();
        Locale locale = facesContext.getCurrentInstance().getExternalContext().getRequestLocale();
        String pattern = AppUtil.getFourDigitYearPattern(DateFormat.SHORT);
        SimpleDateFormat sdf = new SimpleDateFormat(pattern, locale);
        return sdf.format((java.util.Date)object);
    }AppUtil.getFourDigitYearPattern(DateFormat.SHORT) provides a date pattern, e.g. "M/d/yyyy" for locale en-us. In the above code I did not include try-catch blocks to make it more readable.

  • A problem with threads

    I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
    Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
    My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
    Thank you in advance,
    Lefty

    This was one solution from the socket programming forum, have you tried this??
    public Thread MyThread extends Thread{
         boolean active = true;          
         public void run(){
              ss.setSoTimeout(90);               
              while (active){                   
                   try{                       
                        serverSocket = ss.accept();
                   catch (SocketTimeoutException ste){
                   // do nothing                   
         // interrupt thread           
         public void deactivate(){               
              active = false;
              // you gotta sleep for a time longer than the               
              // accept() timeout to make sure that timeout is finished.               
              try{
                   sleep(91);               
              }catch (InterruptedException ie){            
              interrupt();
    }

  • Problem with Threads and a static variable

    I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
    Code functionality:
    A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
    The problem as far I understand is:
    Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
    Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
    Thanks,
    B.D.
    Code:
    private static volatile boolean bChanged = false;
    private static Thread objMainProcess;
       protected static void Init(){
            objMainProcess = new Thread() {
                public void run() {
                    while( objMainProcess == Thread.currentThread() ) {
                       GetState();
            objMainProcess.setDaemon( true );
            objMainProcess.start();
        public static void initStatusTimer(){
            if(objTimer == null)
                 objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
                    public void actionPerformed( java.awt.event.ActionEvent evt){
                              SetState();
        private static void SetState(){
            if( objMainProcess == null ) return;
            synchronized( objMainProcess ) {
                bChanged = true;
                try{
                    objMainProcess.notify();
                }catch( IllegalMonitorStateException e ) {}
        private static boolean GetState() {
            if( objMainProcess == null ) return false;
            synchronized( objMainProcess ) {
                if( bChanged) {
                    SendMessage();
                    bChanged = false;
                    return true;
                try {
                    objMainProcess.wait();
                }catch( InterruptedException e ) {}
                return false;
        }

    Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
    Again as you said, There is a reason I can't call sendMessage() inside setState().
    The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
    Thanks,
    B.D.

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
    troy.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.
    Graeme.Hi Graeme,
    I dont understand what you mean by redirection to file? some of my code below.

  • Problem with threads and camera.

    Hi everybody!
    I've a problem with taking snapshot.
    I would like to display a loading screen after it take snapshot ( sometimes i
    have to wait few seconds after i took snapshot. Propably photo is being taken in time where i have to wait).
    I was trying to use threads but i didn't succeed.
    I made this code:
    display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while((!performing.isShown()) && (backgroundCamera.isShown())){
                        Thread.yield();
                    notifyAll();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        this.wait();                   
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();This code is sometimes showing performing screen but sometimes no.
    I don't know why. In my opinion performing.isShown() method isn't working correctly.
    Does anyone have some idea how to use threads here?

    Hi,
    I've finally managed to work this fine.
    The code:
           Object o = new Object();
           display.setCurrent(perform);               
            new Thread(new Runnable(){
                public void run() {               
                    while(!performing.isShown()){
                        Thread.yield();
                   synchronized(o) {
                      o.notify();
            }).start();
            new Thread(new Runnable(){
                public void run() {
                    try {
                        synchronized(o) {
                           o.wait(1);
                    } catch(Exception e) {
                        exceptionHandler(e);
                    photo = camera.snapshot();                               
                    display.setCurrent(displayPhoto);
            }).start();

  • Problem with threads hanging

    We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
    We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
    A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).

    String.java line 1446 for this jdk allocates a new String object, and all the other threads in this state also are creating new objects or arrays, etc.
    We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

    Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

    Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there.  Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this. 
    We're using the following memory options:
    -ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
    -verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
    Thanks!
