Manage the CRUD operations in unique transactions

Hello

How can I manage the CRUD operations in single transactions using JTA? While each a separate transaction operations will not be created? Please provide examples for this topic.

Thank you.

Hello

Yes, the transaction manager is implemented through the Java API of the Transaction (JTA).

The JTA includes two main interfaces for the management of transactions, javax.transaction.TransactionManager and javax.transaction.UserTransaction.

See: transaction manager

And to use transactionManager, you need to inject exactly as you said.

Why do a bit better with Demarcation of Transaction:

TransactionDemarcation td = new TransactionDemarcation();
boolean rollback = true;
try {
  td.begin(getTransactionManager());
 // all changes in items of repository
  rollback = false;
} catch (TransactionDemarcationException e) {
  throw e;
} finally {
  try {
  td.end(rollback);
  } catch (TransactionDemarcationException tde) {
  throw tde;
  }
}

  • CRUD operations.

    I create crud operations in a workflow.

    Untitled.png

    When I'm clicking addJob, fragment works. The question is: if I did not build all the data, and in my opinion 'read only table' that show all the data. I found the new, blank record added.

    Untitled.png

    That is why I sequence in entity on pk.

    How do I manage so no data and click back2, no added record?

    My version of Jdev is 12.1.3

    You mean to delete the line? Then 'delete' would be the method.

    Or you can use the rollback method. However, the rollback undoes all the changes made since the last commit. It could do more that you like.

  • How to manage the browser close event and session timeout

    Hello
    In fact, in my page ther is a table with records. If I select a record, it navigates to the next page and the status of the transaction will change
    'ONGOING'. Now, I want to change the status of the operation AGAIN if I close the browser or if the session expires. Please help me.

    Hello

    Words Anand is OK, if you want to access the new page, then you must keep the AM that will keep the data entered in the user interface in the cache of vo. There is no need to manage the State of the transaction.

  • How to manage the runtime at the stage of PreUUT error when running in parallel mode

    I would like to run Test DUT in parallel mode, and some actions are made in PreUUT of this kind of reading serial number and control of the aircraft.
    The model of process don't goto PostUUT step when the runtime error occurs at the stage of PreUUT, so I would like to add a few things to check if error in the cleaning of the sequence and return to the configuration at PreUUT stage, but I think it's jumping all the actions of installation and the main stage?

    What should I do if I want to go back to run PreUUT again after the first run when the runtime error occurs?

    Or, is it a good way to handle this kind of error withour restart of the program?

    Bandaged,

    There is no decent way to do this. The reason is the following: TestStand assumes that failure in the facility to a unique testsocket mechanism, it is senseless to proceed with this testsocket at all. It is recommended to manage the routines of judgment in this case using the SequenceFilePostStepRuntimeError callback. You also can use this callback to execute a loop on the step that creates the error until the error is resolved.

    By default, TestStand does not support a tribute of the error but the proceedings concerning the execution of shots. You can just ignore the error (deletion of the error indicator) or you can implement your own features. For example, you can set a custom fault indicator which will be evaluated as a first step in your hand. If the flag is set, ignore you everything in your hand.

    I know that this suggestion seems not to be a good idea because it's 'hack mack', but it solves your problem. TestStand, as already the State evaluates the execution errors that occur in the PreUUT as to the deficiencies of the system and carry out any checks is not suggested.

  • Hard drive partition and install the new operating system

    HY,

    If I partition my hard drive and I install a new OS (E.g. Ubuntu 14.04) my warranty ends?

    Thank you

    SA

    Hello

    No, it will not void the warranty but HP only supports the problems with the original operating system and prove the operation of the equipment of the original OS.

    Do the recovery disks and keep them safe before so that you could go back to factory settings if there is no problem of partitioning.

    Recovery partition usually works after partitioning, depends on your luck, but you could make the 'Active' Partition in disk management and try for recovery if it works or not.

  • How to transfer the old operating system to Windows XP on a drive USB3 to allow the start of a new XP computer

    I have Windows XP SP3 on a Dell computer. I have a new computer with Windows 7 Pro.

    I want the option to be able to start my new computer with XP and run it as an alternative to USB.

    Is there a way I can completely transfer the contents of the drive WITH the XP OPERATING SYSTEM on a regular external USB3 drive so I can start the new computer using XP works like the operating system, when I need?

    Thank you.

    You do not have.  Windows XP doesn't work this way (start of the external drive).

    You can virtualize the old computer (physical to virtual conversion) and run it as a virtual machine on your new system.  Although, honestly, it would be a bit beyond the type of assistance usually given in these home user forums.  A Google search would be ways to virtualize a physical system and/or choose which Manager of virtualization that you want to use (Microsoft VirtualPC, VirtualBox, VMware Player/workstation, etc...)

  • Want to download 10 W but not able to do that, during installation, a problem arises and the previous operating system is restored.

    My laptop is preinstalled with Windows 7 Home Basic.  At the free launch Windows 10 I downloaded the same and after 2 months, the hard drive crashed.  The repair shop trying to fix formatting, but could not revive.  This is why I bought a new hard drive and repair charge shot Windows 7 Ultimate edition.

    Now, I want to download 10 W but not able to do that, during installation, a problem arises and the previous operating system has been restored.  When I posted the question about how to solve this problem, I was told to try the download by way of USB/ISO file.

    Now my question is that

    one) can I reload Windows 7 Home basic as I have the product key?

    (b) I can then download Windows 10 according to the normal procedure?

    I'm not tech savvy, afraid to download files in USB and then load into the laptop, so this question.

    Concerning

    S Subramanian

    Original title: Windows 7 Home basic

    You can directly download Windows 10. Windows 7 complete edition currently installed is not genuine.

    When you upgraded from a previous version of Windows, what happened is that (your PC) hardware will get a digital right, a unique signature of the computer which is stored on the Microsoft Activation servers. The real Windows 7 or Windows 8 license you were using previously will be exchanged with a key to the diagnosis.

    Whenever you need to reinstall Windows 10 on this machine, go just to reinstall Windows 10. It automatically reactivates.

    Therefore, there is no need to know or get a product key, if you must reinstall Windows 10, you can use your Windows 7 or Windows 8 product key or use the reset function in Windows 10.

    Step 1: How to download official Windows 10 ISO files

    Step 2: how: perform a clean installation of Windows 10

  • How to use FTP Client and manage the table in BB with JDE

    I'm a newbie to BB development. I have an application in mind, it is a simple ordering application. BB users can send order information to an ftp server. The BB will have some paintings as a customer table and the Order Details table (the two have only a few records). Since cannot use the Services of SDM BlackBerry because the license fees. I'll use JDE to develop the application.  Here are my questions:

    1. What is the best way to manage the tables (read/write)?  RMS, or embedded database (which one?)
    2. is there any ftp client in JDE, api can be used to send data to an ftp server?

    Thanks for help.
    PJ

    The exact figures for RMS sizes are available in this article:

    What is - size restrictions when you use the RecordStore
    Article number: DB-00656
    http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800724/What_Is...

    So that your information is correct, in 4.6 or later, the per application limit went up to 512 KB.  I don't know if there is a limit on a single record in a record store. We must be careful of the terminology here, it's RecordStore or RMS - is not in BlackBerry terms anyway, PersistentStore (see next).

    The BlackBerry offers two other ways to store data.

    The first and most commonly used are called PersistentStore, and it is an a storage mechanism for objects, I am not aware of any restrictions, other than the memory of the device, about the size of an object that can be stored in PersistentStore.  The advantage with PersistentStore, is that you just persist an object helps you, rather than having to convert it to bytes (serialize) before storing and converting new (him deserialize) after reading it back.

    The second way is to write data using the FileConnection API, and you can for example use this to write data to the SD card in the device.

    EFF and PersistentStore use the flash memory in the device.  You don't have to manage yourself.  You treat all that identical objects, the BlackBerry operating system very cleverly manages to bring your items in RAM and save them in Flash, so you don't have to worry about the type of storage you have.

    I hope this helps.

  • Virtual Disk Manager "the device is not ready".

    I don't know about the format from outside, possibly MAC OS EXTENDED. He was not ejected a Mac and will not mount on an operating system MAC or PC (Windows 7 Professional) using Firewire (800 to 800 and 800 to 400), eSATA and USB 2.0. When I use disk management, disk will appear as not initialized and next to the "disk 33", there is a red arrow pointing down. Whenever I open the Disk Manager, the window to initialize the disk appears, but once I chose a style of partition and press OK, the virtual disk manager pops up saying "the device is not ready". I also tried to wipe the drive using CMD, (disc of DiskPart/list / select disk 33/clean), CMD said the drive was clean, but when I went to disk management, without change.

    I'm looking for a way to clean the drive so that it can be reformatted and reused.
