How to build a WDynpro App without JCO destinations in the WAS

Hi,
I would like to configure my webdynpro application so as it can work with several R/3 servers. For this purpose instead of using JCO destinations of the WAS I would like to use JCO clients in the webdynpro code. My question is: how can I make a webdynpro application work without JCO destinations? (knowing that this app should connect to several R/3 systems).
Thanks,
Younes

HI,
Thanks pran for your link it was really helpfull.
I managed to change dynamically modeldata system name using "myModel.setSystemName("myModelDataJCODestination")" function in the webdynpro code. My problem is still not solved because I still need JCO Destinations to make my application works.
Moreover I didnot managed to change metadata and dictinary system name because there are no setters for these attributes in the java class mymodel.java. I have noticed that those fields are final attributes and can be only hard coded.
My two questions are:
+ Is there a way to build an application without specifying at all JCO destinations? Without configuring anything in the wd content administrator.
+ How can I change dynamically metadata and dictionary connection parameters? (Especially changing the language of metadata because in my application it changes from a user to the other)
thanks for answers,
Younes

You don't, this is a security measure which can't be changed, however, if you purchase another App within 15 minutes your password should not be required.

If None is not available - On your computer launch iTunes and click "iTunes Store" in the left navigation pane. Click the "down arrow" next to your name at the top right side of the page and click "Account." Enter your username and password and click "View Account" to log into your account information. Next to your Payment Type, click "Edit." Select the "None" button and click "Done." Confirm that your card has been removed by returning to the Apple account information screen.

When you create an Apple ID for any of these stores, you will need to provide a payment method for purchases. The available payment methods vary by country, but typically you can use:
Credit cards
iTunes Cards
iTunes Store Gift Certificates
Content Codes
Store credit (including Allowance Account balances)
ClickandBuy
PayPal
In countries where the iTunes Store only sells apps, the accepted payment methods are Visa, MasterCard, and American Express. Other payment types such as gift cards, store credit, monthly allowances, ClickandBuy, and PayPal are not accepted. Depending on your App Store country, prices may be listed in your local currency, US Dollars, or Euros.

HT204088 how do i get free apps without putting in itunes card, or credit card

wondering how i can get free apps without putting in itunes card or credit card, wont let me do this....

Is it a new account ? If it is then unless you use the instructions on this page when creating a new account : http://support.apple.com/kb/HT2534
then credit card details will need to be entered before the account can be used to download any item from the store - you should be able to remove your card's details after entering them.
If you don't have a credit card then you will need to create a new account, and this time use the instructions on that HT2534 page when creating it. If you want to use the same email address then you will need to replace it on that account first e.g. by tapping on it in Settings > iTunes & App Store on your phone and logging into it, via the Store > View Account menu option on your computer's iTunes, or via http://appleid.apple.com

How can you delete an app without losing saved data/progress?

How can you delete an app without losing saved data/progress? Is there a way through iCloud? I have an 8gb 4th gen iPod touch. I have a lot of music, so with 8gb, space is limited. Some apps I have take up 20-30 MB. Some of these games I don't play that much, but I don't delete them because I have made a lot of progress (levels, scores, acheivements). It would be nice to delete some of these 30 MB apps that take up precious space, and them redownload them in the future when I have more space, but without having to start the whole game over.
Also, I read somewhere that there might be a way to do this with iCloud, but I don't really know how.
Thanks!

This is the only way I know of. It is messy though.

how do I close down apps without deleting them?

If you want to completely exit the apps, then press the home button twice to access the multitasking bar. Then press and hold on one of the apps, they should start wiggling, and a red minus sign should appear in the corner of every app. Press the red minus sign and the app should disappear signifying that it has successfully been quit.

How do I 'purchase' an app without actually downloading it?

I have an MDM software preventing me from downloading apps to the device that aren't approved, but I have access to the App Store. How do I 'purchase' an app without actually downloading it to my device? I just want to save some apps to my iTunes account while the app/s have their deals so I can use them for my iPod later, which I won't have access to until November.

Can't do that. I don't have a personal computer and the computers in the libraries where I am don't allow software to be installed. Is it possible to do from apple.com? Or is it possible to 'purchase' it by clicking install, stopping the download, and erasing it from the device before it finishes installing? (Allowing it to finish installation would trigger my MDM As far as I am aware.)

Hi,
For portability issues always develop applications using sun implementation which can be configured for any vendor application servers.
Web services developed with jwsdp will work in webloigc 8.1 simply, take the examples from sun and simply deploy it in weblogic 8.1 it will work like gem with simple settings.
Just change the libraries with jwsdp ones.Place the
jwsdp lib.How to do this is ; place all these jars in the classpath before the exisiting classpath configuration.
Classpath=jwsdplibs;......
This is enough for deploying the webservice server side.
For using the client you have to change the default soap libraries used by weblogic with sun jar files.
See example from bea for client implementation.override the system property.

How do I clear updated apps listed by date in the Updates section of the App Store app?

How do I clear updated apps listed by date in the Updates section of the App Store app?

Hi rowiny,
depending on what exactly you mean with "clear", it is a bug. See this thread: App Store Updates Do Not Clear
If you update your App's via iTunes, and not "over the air", the badge count on the AppStore-app icon is wrong, and the list shows "available updates" that you can open in the new version. The listing under "Updated #date#" lists only updates that were done OTA in the last month.

iPhone is designed to sync with one computer only, if you sync with another, all your content will be erased and replaced by whatever is on that computer.

Howdy Hestersfree,
This can be done through the App Store on the device that you'd like the app installed on.
Apps on iOS
Open the App Store on your device.
Make sure you are signed in with the same Apple ID used for the original purchase.
Tap Updates from the bottom navigation bar.
Tap Purchased on the resulting screen.
Locate the app in your Purchased tab.
Tap the download button.
The app will begin downloading and you'll be taken back to your home screen.

How to use X-Fi Effects without selecting SB as the default sound device?

How to use X-Fi Effects without selecting SB as the default sound device?Hello everyone,
That's my situation.
I have Sound Blaster X-Fi Go sound card and I am using SRS HD Audio Lab. SRS HD Audio Lab was selected as the default audio device and X-Fi effects (X-Fi CMSS-3d, Equalizer etc.) was working without any problem in Windows Xp. I have Windows 7 now and when i select SRS HD Audio Lab as the default device, Creative effects are not working, i must select "SB X-Fi Go!" to get them working but i can't use SRS HD Audio Lab in that case. SRS is also using SB X-Fi Go sound card as the output and volume adjustment on console launcher is working but something is disabling the effects. Any solutions to enable effects ?
Thanks.

If the kernel modules for your sound card and webcam both support the index parameter (use modinfo to find out) then adding
options <name_of_preferred_card's_kernel_module> index=0
options <name_of_second_card's_kernel_module> index=1
to /etc/modprobe.d/modprobe.conf (or another modprobe conf file of your choice) should solve the problem.
