Loading DAO and SQL on demand for the request
Hi,
I have a requirement, where I need to load the SQL queries for the specific DAO on demand when the request has been made. This will ensure that I am not loading all the objects as I will be loading only the objects which I am going to work with. That is the main idea behind this operation. I am using JPA for back-end which connects to Oracle DB. Whether it will be better to load all the module specific DAO's on-demand using lazy-init="true" in Spring and load the specific SQL queries for those DAO's? In hibernate we are using named queries. Hence, please do suggest me how we can go about this?
Whether it is better to load the DAOImpl and specific SQL for those DAO on demand (lazy-init="true")?If that is the case how we can do it? Please give me some examples on this? Whether we need to configure the named SQL queries in text file or XML? Which one will be better.Also suggest me which will be the best way of handling this? Any ideas are really appreciated.
Thanks.
I am unclear on if this question is a JPA question or a Spring/Hibernate question. If it is the later, you might try asking elsewhere, as this is a TopLink/JPA forum - TopLink is a JPA provider that includes EclipseLink. If it is JPA, you might make your question more clear, as JPA does not allow defining named queries in a text file and defining a query will not return entities from the database. JPA does allow defining queries in orm.xml or though annations on the entities themselves, and in JPA 2.1, you can add named queries in code. And entities are only returned when the query is executed, so you might want to explain a bit more what you are trying to avoid loading.
Best Regards,
Chris

I was changing my desktop screen saver in system preferences>screen protection. Now it says it is "Loading Images" and won't stop. The Colourful wheel goes around for ever and It does not stop. Can anyone help me?
Welcome to the Apple Support Communities
I have seen a lot of cases like your issue, and it's easy to solve.
First, open Disk Utility, select Macintosh HD in the sidebar and repair permissions. Sometimes, a permission can be damaged and it makes that an application doesn't work properly.
If that doesn't work, open Finder, select Go menu > Go to Folder, type ~/Library/Prefereces, delete "com.apple.desktop.plist" and "com.apple.systempreferences.plist" and restart -
How do i insert a splash screen or a loading screen and a application image for a phone app on Dream
How do i insert a splash screen or a loading screen and a application image for a phone app on Dreamweaver 6, 5.5 had the mobile application setting that is seemingly no longer present? and i also heard you can use animanted backgrounds on the mobile application in dreamweaver 6 but figuring out how to set the splash screen and application image like it was in 5.5 would be nice. All i can get to pull up is the web application i developed i am trying to build into a phone app on google chrome, if i could officially designate it as a phone app where i can set each splash screen and app image to where it is recognized as a phone app that would be really nice.
Duely noted, the server will still not connect, so i have left an inquery in the suggested forum.

Any ideas on how that problem can be mended if the solution is in my hands?? I haven't used PhoneGap Build recently, but I have seen several reports about problems connecting to the server. One suggestion that I've heard is that there has been unexpectedly high demand on the server since the launch of Edge Tools and Services as part of the Creative Cloud last month. As far as I know, the only thing you can do is wait, and try again later. You could also try posting in the PhoneGap Build forum: http://community.phonegap.com/nitobi/products/nitobi_phonegap_build.

Dear S&OP community,
I am getting following error while creating a planning ares in a newly installed sandbox. "Enter values for planning horizon From and planning horizon To for the storage time profile level".
This what I did...
1) Created new attributes and master data objects and activated them successfully.
2) Time profile created and activated successfully
3) Trying to create planing area by assigning time profile in step 2 and assigned master data from step1..Unable to save the data and system returns
this error - "Enter values for planning horizon From and planning horizon To for the storage time profile level"
My understanding is time profile needs to be active but doesn't have to have values...
Any help is appreciated.
Thanks,
KrishnaYS,
Here are my time profile settings
Level Name Display Horizon - Past Display Horizon - Future
1 Monthly -6 11
2 Quarterly -2 3
3 Yearly -1 2
Time profile is active and but time profile data is not loaded
Thanks,

I need to reinstall my original factory disc and reset my computer to the beginning. It currently has lion. Do I need to erase my HD first to clear and make new room for the install disc.
Prepare Your Mac for Sale
Boot from the OS X Installer Disc One that came with the computer. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select the startup volume from the left side list then click on the Erase tab. Set the format type to Mac OS Extended (Journaled) then click on the Options button. Select the one pass Zero Data option and click on the OK button. Then click on the Erase button.
Note: You can skip the Zero Data option if you are not concerned about removing sensitive personal data from the hard drive. If you choose to skip this part of the process then it is possible for others to recover data from the hard drive. The Zero Data procedure will prevent others from getting access to your personal information.
This process will take 30 minutes to several hours depending upon the size of the hard drive. After formatting has completed quit DU and return to the installer. Now complete the OS X installation. At the completion of the installation do not restart the computer. Instead just shut it off. The next user will be presented with the Setup Assistant when they turn on the computer just as it would if new out of the box. -
I forgot the passcode to turn off restrictions. I have restored my iPad back to the factory settings and then synced it with the latest backup. The restrictions are still on and it is asking for the passcode. Can someone tell me how to get that off.
The only option is to wipe the device clean and restore it to factory settings. Hope you have a backup.
Follow the instructions in iOS: How to back up your data and set up your device as a new device http://support.apple.com/kb/HT4137 to restore the device to factory settings.
Once you have setup the device as a new one, you can then sync it back with your iTunes account and all your music, apps, contacts and any other content sync'ed with iTunes will be loaded on the device. Any content that is stored only on the device and not sync'ed with iTunes, like app logins or data, will be lost during this process. Be forewarned that this is a long process and can take a couple of hours or more to complete. This can be painful, but it is necessarily so to prevent users from working around the security settings. After the restore is complete, you can setup a new Restrictions passcode. Make a note of the passcode to avoid this situation in future.
Cheers, Tom -
PLEASE HELP PLEASE PLEASE
Did you try the things listed here? Error 3194, Error 17, or "This device isn't eligible for the requested build" - Apple Support Is your device jailbroken? Have you ever used the computer to jailbreak a device? Are you trying to load an iOS other than the current one? What version of iPhone are you using? Is this occurring when attempting to update via iTunes and the computer?

Downloaded Mountain Lion on my iMac. Why is it so slow opening up from sleep and taking so long for the wireless mouse to engage?
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless. -

I downloaded Iphoto 11 9.2 from the apps store (was on iphoto '09 before version 8.x) and when opened it for the first time it tried to update my photo librery and ended up corupting it to the extreme that I had to get a backup from time capsule and downgrade my iphoto version. I spent yesterday 6 hours at the genius bar in an apple store and they were not able to provide me with any other solution. In the emantime, I have to forget about about photo streaming... Any idea, is this a bug that somebody knows how tp fix?
In fairness, this isn't an issue in iPhoto 11 but one in your Library. Some file or other in there is damaged and that's what causes the crash during the upgrade.
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. -

I've an apple ID used to buy off iTunes and a mobileme account for the calendars and contacts. How can I move the calendars and contacts to the older apple ID and use it for iCloud?
If you remeber the password to that Apple ID then follow these steps
1 - Make sure you have an email address that is NOT an Apple ID
2 - Go to AppleID.Apple.com
3 - Where it reads Manage Apple ID - Sign in
Once you are signed in want to make sure the email address you are wanting to use is NOT set up as a "Recovery/Rescue" email for this account.
[To check this - Main page where you see Primary ID - below do you see the email address you want to use listed towards the bottom? Yes - Delete / No - Good ./. If made any adjustments "Save" Next on the left select "Password & Security" - Answer your security questions you set up "if you have any" then scroll towards the bottom and check to see if you see the email address you want to use. Yes - Delete / No - Good] <-> Also you can change your password on this page as well. Any adjustments made "Save"
Once this is done go back to the main page where you should read "Primary ID" and change the email address that is showing to the new email address youo want. "Save" Done
I learned this not to long ago and worked for me. Hope this helps you! -
An Apple pop up keeps coming up anytime I try and use my phone and it has an old Apple ID and it is asking for the password. How do I get it to stop?
That means there is content on your phone...music and or apps...originally obtained using his Apple ID. Such content is forever tied to the account used to originally obtain it and cannot be transferred to another Apple ID. Your only choice is to identify and delete this content.

Hello Everyone,
I would like to have a discussion on the issues, which I am facing at the time of Exporting the Sales Price List and Purchase Price List for the Materials from
SAP Business ByDesign (SAP Cloud).
(1). Sales Price List :
We have maintained Customer Group Specific Sales Price List for the Materials in the following Location.
Location : Product and Service Portfolio Work Center > Pricing > Price Lists > Customer Group Specific Price List (Type of Price List)
Target : We want to export the entire records in some reports or excel sheet.
Records : Number of Materials in the Customer Group Specific Price List is more than 2,00,000
Issues :
(A). In the SAP Business ByDesign Screen we can filter by number of records but we can export till 50,000 records.
And if we are trying to export records more than that limit, then it throws "HTTP 500 Internal Server Error".
(B). We could not find any SAP standard reports in Product and Service Portfolio and/or Business Analytics Work Center
for getting the entire record set of the Sales Price List, so that we can have the entire set of records together.
Searching For :
(A). Is there any SAP reports or data source available for getting the entire Sales Price List records?
(B). Can we have any other filter conditions for exporting the Sales Price List records in a single shot or module wise?
(2). Purchase Price List :
We have maintained the Purchase Price List for the Materials in the following Location.
Location : Product Portfolio Work Center > List Prices > Active List Prices (Type of Price List)
Target : We want to export the entire records in some reports or excel sheet.
Records : Number of Materials in the Purchase Price List is more than 4,00,000.
Issues :
(A). In the SAP Business ByDesign Screen we can not see more than 10,000 records and the actual number of
records are more than 4,00,000. We could able to download the records till 10,000 but that is not sufficient.
We want to export the entire records in an excel sheet.
(B). We could not find any SAP standard reports in Product Portfolio and/or Business Analytics Work Center for
getting the entire record set of the Purchase Price List, so that we can have the entire set of records together.
Searching For :
(A). Is there any SAP reports or data source available for getting the entire Purchase Price List records?
(B). Can we have any other filter conditions for exporting the Purchase Price List records in a single shot or module wise?
Please go through the attached screen shots for the references and more clarity on the issues.
I am waiting for the valuable responses.
Thanks and regards,
Susanta Dey Sarkar
