Updating DB from beans with transactions

Hello,
I have a 4 step form to input data from a user.
step1.jsp, step2.jsp, step3.jsp, step4.jsp, submit.jsp
For every form, I am using a javabean (jsp:useBean) with session scope so that I can update all at the end. So in step2.jsp, I set the properties of Bean1, in step3.jsp- the properties of Bean2... and finally in submit.jsp I get all the 5 beans with session scope.
I now want to insert values from these different beans simultaneously into a Database. (single commit)
If I want to use Transactions, how can I get the values from these beans (Bean1, Bean2, Bean3, and Bean4) to a single class? Or can you suggest another method?
Thanks.

why not just use 1 object for all pages anyway?
why 4 beans, is it necessary?I'd like to have multiple beans. Is there a way it can be done?you should know that you can create a class to hold whatever you want
and you should also know that you can copy data from one class to another
so of course it's possible
what are you asking?

Update table from SM30 with automatic Time Stamp

Hi,
I have created a table maintenance generator for updating table from SM30.
Now there are fields in my table which are CRETING TIME and CHANGING TIME. Both being TIMESTAMP field (datatype: RSDDTZNTSTMPS).
Is it possible while user updates records/create new record in the table from SM30, these time stamp field to automatically get populated.
Also is there any F4 help available for TIMESTAMP field?
ags.

Hi,
You need to do two things inorder to get the desired results.
1) Go to Screen Layout of the Screen created by table maintenance generator and make the date/time columns to DISPLAY ONLY. This will ensure that user is not able to modify the values at runtime
2) Write the code in PAI of the Module pool program to populate the values at runtime using Sy-datum/sy-uzeit. (Hint : Search for INSERT/MODIFY statements which will show the location before which you need to write your logic)

Disable transaction box and menue from wingui with transaction iview

Dear all,
has anyone a solution to disable or hide the menue and transactionfield in a portal transaction iview thats called with wingui.
Webgui is no solution.
Best regards
Thorsten Stracke

Hi Vineeth and Ramganesan,
thanks for quick response, this will be a option when all clients shoul use this behavior.
I search for a solution, where i can decided in a view to switch it of. Normally i can attach dynpro fields and values with the dynamicparameter, if this can use for hide .. the box or some functions in the gui state.
An other idea is to use a new status for the reports and transactions, but i don't know who use this as parameter.
Best regards
Thorsten

Cant update apps from AppStore with iOS 8

After I upgrade my iPad mini retina (A1490) to iOS 8, I found all my apps cannot update in AppStore.
Neither clicking on the 'update' button for each app nor 'update all' in AppStore will work, and no progress was made, just the round indicator circling forever.
Has any one met this problem and know what is going on?

Did you do the "erase all content and settings" before performing the restore?? That was the key for me. I had tried all the "normal" things, reboot, hard reboot, etc.
It had trouble even during the complete restore - it stalled at one particular app for a long time (15-20 minutes). I disconnected the lightning (USB) cable, waited 30 seconds, reconnected and it picked up the restore.
Still painful as most of my application data had to be restored through each app. Kindle books reloaded, etc.

Bean-managed transaction with EJB 3.0

Hi,
I try to get a bean-managed transaction example running with EJB 3.0 under GlassFish v2ur2.
In order to demarcate the scenario I have to get me the UserTransaction which I get from the SessionContext. I would like to use it then like: UserTransaction ut = context.getUserTransaction();
I tried to get the SessionContext with the help of the EJB method setSessionContext which should be called by the container after instance creation.
However, setting a log output into that method does not show any call of this method.
So, how can I get this method called or is there another way to get the SessionContext for the UserTransaction to work ?
Are there any good and fully implemented examples for bean-managed transactions ?
Thanks for your help.
Regards

I found the solution for that my SessionContext was NULL and I could not use the UserTransaction.
The reason for it is that I injected the EJB with @EJB into my servlet and did a MyBean mybean = new MyBean();
That leads to a SessionContext which is NULL within my EJB.
If I use it without instantiating it it works fine.
Again, thanks for your help. At least it pointed me into the right direction.
Regards

Update data from ODS to ODS with infopackage selection

Hi,
I am trying to update data from one ODS to another ODS with selection criteria in InfoPackage which is created manually.For Full load I can give selection criteria in InfoPackage. When I initialize data Selection is greyed out even selections for Full load exists. Please advise me how to give selections for delta loads from ODS to ODS loads.
Thanks in advance.
Ram

Once you started an ODS as destination in FULL mode from a DS you cannot get back.
So if you want to update from ODS to ODS using Change Log but considering only some data records you could create an Update Routine with a Start Routine that DELETES undesired records (e.g. DELETE DATA_PACKAGE WHERE ...) and then start an Init-Delta Loading.
Hope it helps

I recently bought, from the original website of Adobe, Photoshop elements 13. However, when I go with my mouse pointer over the menu, It hangs or he works very slow. Does anyone have an idea how I can fix it? I have already downloaded updates, both from Adobe and Windows. I have a new pc with window 8.1.

It could be a coincidence, but I rebooted the machine and (knock on wood) PSE13 seems to be working ok.

Can i update itunes from one computer to the other with a thumb drive

i have a computer that has no internet access but a laptop that does. is there a way i can update it with a file on a thumb drive?

Hello Boyesreef,
It sounds like you are wanting to update another iTunes library with files you have on a flash drive. You should be able to import them with this info:
To add files to your iTunes library, you can use these options:
Drag files from the Finder to the appropriate icon on the left side of the iTunes window.
Choose File > Add to Library (on Windows, choose Add File to Library or Add Folder to Library) and select the song or folder that you want to add.
From: iTunes: About the Add to Library, Import, and Convert functions
http://support.apple.com/kb/ht1347
If your end goal is that you would like both libraries to match on both computers, you can use the following article to copy the more complete library to the other computer all in one go:
iTunes: How to move your music to a new computer

All the very best,
