Problem with the persistent store & object

Hello

I store 2 types of persistentObject in PersistentStore. I find the problem when retrieving the Typeobjet2. The code is:

    private void GetPersonFromPhone() {
        synchronized(store) {
            data = (Vector) store.getContents();
        }
        System.out.println("\\\\\\\\\\\\\\\\\\  Into GetPersonFromPhone Data = " + data.size());
        PersonInfo pi = null;
        Person p = null;
        for ( int i = 0; i < data.size(); i++) {
            System.out.println("Object Got i = " + i + " - " + data.elementAt(i).getClass().getName());
            if (data.elementAt(i).getClass().getName().endsWith("PersonInfo")) {

                  .....
                  data.removeElementAt(i);
            }
        }
         p = null;
        pi = null;
        return;
    }

    private void SavePersonsToPhone() {
        PersonInfo info;
        System.out.println(" To SAVE Persons = " + personVec.size() + " To Store Data Size = " + data.size());
        for (int i=0; i < personVec.size(); i++) {
            info = new PersonInfo();
            data.addElement(info);
            p = null;
            info = null;
        }
        System.out.println("Now DATA size = " + data.size());
        synchronized(store) {
            store.setContents(data);
            store.commit();
        }
       // Dialog.inform("Success Stored");

        info = null;
        return;
    }

 Results

Nobody GOT = name = Mr John Micheal, Email =, URL = store/samples/pictures/Quiver_Tree.png, Send = true
Size PersonVector = 1
Object obtained I = 3 - src.se.PersonInfo
Nobody GOT = name = Peter Simon, email = [email protected], URL = store/home/user/iBeloved/photo1, Send = true
Size PersonVector = 2
GOT people = 2 size = 3 data store

Add new record

Person - McMillan Desilva, [email protected] , SentEmail = false

To SAVE the people = 3 to the data store size = 3
Save I have 0 - name = Mr. Micheal John = Email, URL = store/samples/pictures/Quiver_Tree.png, Send = true
Added Mr. John Micheal, Email = true to vector to the store
I save 1 - name = Peter Simon, email = [email protected], URL = store/home/user/iBeloved/photo1, Send = true
Peter [email protected], Email added = true to vector to the store
Save I have 2 - name = McMillan Desilva, Email = [email protected], URL =, Send = false
Added McMillan detailed [email protected], email = false to Vector to the store

The NEXT TIME that I RAN the APPLICATION

Nobody GOT = name = Peter Simon, email = [email protected], URL = store/samples/pictures/Cascade.png, Send = true
Size PersonVector = 1
Object obtained I = 3 - src.se.PersonInfo
Nobody GOT = name = Peter Simon, email = [email protected], URL = store/home/user/iBeloved/photo1, Send = true
Size PersonVector = 2
GOT people = 2 size = 4 data store

To SAVE the people = 2 to the size of the data store = 4
Save I 0 - name = Peter Simon, email = [email protected], URL = store/samples/pictures/Cascade.png, Send = true
Peter [email protected], Email added = true to vector to the store
I save 1 - name = Peter Simon, email = [email protected], URL = store/home/user/iBeloved/photo1, Send = true
Peter [email protected], Email added = true to vector to the store
DATA size now = 6

You CAN SEE FROM THE results, how the data changes and incompatibilities. Sometimes he gives good resutls sometimes incompatibilities. Someone can say, where I'm going wrong or what makes the results of the get code.

Thank you

Not looked at seriously, but there seems to be a coding bug in this piece of code:

for (int i = 0; i)< data.size();="" i++)="">
System.out.println ("object got I I =" + i + "-" + data.elementAt (i) .getClass () .getName ());
If (data.elementAt (i) .getClass () .getName () .endsWith ("PersonInfo")) {}
....
data.removeElementAt (i);
}
}

Say that the vector has 3 elements inside.  You spend the first at the beginning of the second loop, I = 1, and the for loop see data.size () 3.  Then you deal with the second and delete.  Then when you go back to the loop for I = 2, and data.size () = 2, so you never treat a third.

Of course, logic could just as easily result in code by jumping the elements of the vector.

Maybe that's your problem?

  • Problem with the virtual store to Windows 7 basic, home

    Hello, I have a problem with Windows 7 64-bit home basic e-store. What happened is that I have a program that I use to make small electronic circuits and it was working fine until a few days when I noticed that the design I was doing seemed to be locked - I can open it but I can't open the second tab of the main window, which I should be able to do. After much research I discovered that the problem was caused by the virtual store of Windows - system registers my designs. I need to disable this feature because it prevents me from doing my work. I tried many things including turning off virtual store in REGEDIT and it doesn't change anything. I have another computer with Windows 7 starter and I have no problem there at all. I searched the internet for ideas and found two to this site http://www.askvg.com/how-to-tweak-user-account-control-uac-options-in-windows-vista-home-basic-home-premium/

    In all no joy. Help, please. I would appreciate only the answers that have been tried and tested not something that is supposed to work.

    Thank you, Ed

    I have a program that I use to make small electronic circuits and it was working fine until a few days ago.

    Given that things worked fine until a few days ago I would use system restore to set Windows back a week.

  • I have a problem with the Windows Store updates.

    All of a sudden the app store came with updates for 4 items, the observer of the team, finance, travel and news. First of all, I don't have to install outside the viewer of the team.  So I install all updates of four, and then uninstalled, finance, travel and news. Then they cam right back up as updates in the store windows again. Windows store needs an update.

    There is not need to troubleshoot... this question is server-side, no amount of troubleshooting/patches help right now, see the thread I posted above and read it

    In addition, Windows Update has nothing to do with the update of the modern applications, they do not automatically install it, this will change in Windows8.1 (apps will be able to update automatically)

    Ivan,

    If it's on the rectangular objects, you may have encountered the bug Rectangle Live which is limited to the MAC versions from 10.7 and 10.8, but not of 10.9 (Mavericks) or 10.10 (Yosemite). If all goes well, the bug will be fixed soon.

    Thus, a switch for the Mavericks or Yosemite with a reinstall might be the way to solve it here and now.

    To get around it, in each case, it is possible to develop direct Rectangles to get the normal old shaped rectangles or Pathfinder > unit, or use the scale tool or the free transform tool.

    A more permanent way round that is to create normal old shaped rectangles, after running the free script created by Pawel, see this thread with download link:

    You try to migrate a portlet in JDev 10135 FOR PS1? If so, you can try to do the following:

    -Create a consumer with portlets of the server application embedded in 10.1.3.5
    -Open jdev PS1 and import the settings of the 10.1.3.5 system directory
    -Refresh record producer
    -Run the page again

    I hope this helps.

  • Remote control/software Apple TV with the App Store problems

    Seems ridiculous that a Sept 2016 4th Gen apple TV purchase has the same problems of connectivity with the App store. Impossible to connect, or even choose App store, or spare parts offline, erratic, glitch and acts as a problem of distance, but seems to be a software problem or interface. Obvious corrections or ideas to stabilize or least to increase connectivity to app store with 4th Gen Apple TV/remote control?

    Try a forced reboot. Hold down the home and Sleep/Wake buttons simultaneously for about 15-20 seconds , until the Apple logo appears. Ignore the "Slide to power off" text if it rises. You won't lose anything.

    Then sign out of the iTunes Store and reconnect.

    If you have not yet tried to disable the antivirus/firewall software, then try the following steps to disable them.

    Enable or disable Windows Firewall: http://windows.microsoft.com/en-US/windows-vista/Turn-Windows-Firewall-on-or-off

    IMPORTANT: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software.

If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks

  • Editing an object that I stored in the persistent store

    I store a custom object in the store persistent and would like to add a new Member.  Someone knows how can I do this?  I'd rather not delete it and store an object in its place because what happens if I need to add more members in the future.  This would encourage me to juggle all versions of my object.  Is there a kind of model for version control that I can apply to my objects stored persistently?

    I don't think it will work.  The link that you say talk us too much serialization, but the persistent object is not serialized as part of persistence.  If you want to serialize her, you should do it yourself.

    I'm guessing that you did not design your class being "expandable". And I'm guessing that you do not want your users to have to recreate these data.

    So I investigate an approach to migration.  In the code that gets the persistent store, got it get the object persistent, then check that it is indeed a picture of your old items.  If it is, convert it to an object type, store it in a collection (vector or Hashtable as suggested, for example) and keep the result, by replacing your old array of persistent storage object.  So your new application includes the old class of objects, exactly as it was, which means that you can install it on top of your existing application.  But once your request is used at the same time, the old persistent object is no longer used.

    Does make sense?

    Hello

    This behavior can occur if the antivirus application blocking the app Store or changes due to some recent on the computer.

    I would suggest trying the following steps and check if it helps.

    Method 1:

    Make sure that your PC is up to date

    Make sure that updates are installed on your PC and that your antivirus program does not prevent the application from running. For more information about installing updates for your PC, see Windows Update: frequently asked questions.

    Method 2:

    Run 'Windows Apps Store' convenience store

    You must be logged in as an administrator in order to run the "Windows Store Apps" troubleshooter. This tool can automatically find and fix some issues with applications. It is available in English only, but will work in all languages. You can let automatically try to fix any problems found, or select what you want made repairs.

    http://download.Microsoft.com/download/F/2/4/F24D0C03-4181-4E5B-A23B-5C3A6B5974E3/apps.diagcab

    Method 3:

    I suggest you delete the Windows Store cache and check how it works.

    1. Press Windows + R logo
    2. Type wsreset.exe in the run window, and then press ENTER.

    Method 4:

    Define the Apps approved in third program Antivirus- If you have a third party AV program installed, check its settings to make sure that the app Store works is not changed to be approved. If the AV program has the app as unreliable, it will block and prevent opening the app.

    Let us know the status of the issue. If you need help, please after return. We will be happy to help you.
