Hi
Before you know about ESA, you should know the following things things .
Enterprise: this is Integration different branches of business. (eg integration SD,PP,MM etc into one )
Service: It is a new way of software solutions. we had function modules, Object oriented way such is Service.
In this concept we have two main objects:
Service Providers and Consumers.
Web Service : Web services are self contained and self describing application functionalities which can be processed through internet standards.
EG : Google
Product Availability check
Order Status check
Now you can Definitely understand what is ESA :
SOA : Sevice Oriented Architecture
ESA(Enterprice Service Architecture) :
Web Services which provide business Functionality
Have enterprise quality in scalability, robustness,security, manageability,supportability,
If you want to be familiar with ESA. you go for MVC(Model View Controller concept and Webdynpros) and then registering and deploying service is the last step it is very easy
Good Luck.

What exactly is using data and how can i keep it from using data when im not using my phone?

So i have an iphone 4 and i have used a lot of data this month(like almost 2GB) and i have barely touched my phone outside of wifi areas. I always shut down any apps that use data like youtube, funnypics, facebook, etc. but i do play some games during my breaks at work but they dont require data to play so to my knowledge those games arent using data(or are they?) i just need some help figuring out exactly what on my phone is using data all the time so i can turn it off. Is it icloud? Emails on auto update? Offline game apps(minecraft, sonic dash, the Mr. Series games?) Do all apps use data regardless? Somebody please answer me. And No im not buying a bigger data plan. 2GB is my limit but it seems as though i am hitting that easily with my iphone but the rest of my familyis usually miles away from 2GB and they all have Samsung Galaxy S4s.

My first stop would be in Settings > Cellular if you are on iOS 7. This has a lot of goodstuff. you can turn off cellular data as a who, see your current usage and even see which apps have used data and how much. You can even turn off individual apps form using cellular data (restricting them to wifi only).
I hope this helps!

I'm getting this error statement: XULRUNNER error: platform version 6.0.2 is not compatible with min etc max etc6.0.1 - what is this about and how can it be corrected?

This is what I think may have happened. The other day, Thursday Sept 8th, I shut down my pc in the middle of a Firefox upgrade. Now when I try to access Firefox on my pc, I get this error message:
XULRUNNER Error: Platform version '6.0.2 is not compatible with min Version >= 6.0.1 max Version < 6.0.1
What is this about and how can I retsore access to Firefox on my pc?

If you use ZoneAlarm Extreme Security then try to disable Virtualization.
Do a clean reinstall and delete the Firefox program folder.

Hopefully this will help you. Try placing your iPad in recovery mode again. You may have to try this a few times.

To use iCloud, you must first set it up with your Apple ID on a device with iOS 5 or a Mac with OS X Lion.

I am trying to listen BBC radio news from BBC App, but on pressing the button I always get the error "there was an error playing this radio feed". What is the source of this error and how can I remove it?

I am trying to listen BBC radio news from BBC App, but on pressing the button "live radio" I always get the error "there was an error playing this radio feed". What is the source of this error and how can I remove it?

That is probably just a generic error message and you might not ever know what is causing it. Assuming that you have been able to play live radio with the app in the past (I know nothing about the app) and assuming that all other Internet related functions (Safari, email, etc.) are working properly on your iPad, quit the app completely and reboot your iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If that fails to resolve the issue, you might want to reboot your router, unplug it for about 30 seconds and then plug it in again.

The opperating system I am using is 10.7.4, and updating to the latest version currently. Computer is running fine, except that when I did some utility repairs, I got the warning above, and not really sure what do, in regards to repairing it correctly, not just getting the message off of my computer.
Thank you for your help, and please only contribute if you know about this issue please.

That's a status message which can be safely ignored.

When trying to download Itunes this pops up " key not valid for use in specified state" what does this mean and how can I fix it?

When trying to download Itunes this pops up " key not valid for use in specified state" what does this mean and how can I fix it? I am using a pc laptop if that makes any difference.

Try reading through this thread: key not valid for use in specified state. Possible solution involves moving the RSA folder. Rather than deleting it as aniwack suggested I'd try this:
For "Key not valid for use in specified state" errors try moving the folder RSA from C:\Users\<User>\AppData\Roaming\Microsoft\Crypto\RSA to say C:\RSA (just in case there should be a need to restore it) then try installing again. This folder appears to act as a cache and should be rebuilt automatically as required.

Thanks Larry. I thought so. I will do this weekend. Again, I appreciate your help.
Trying to get updated software – I am not a fan of the cloud stuff. Nothing I can do about it.
Thanks again Larry!

I keep getting message "This page requires a plugin that can only run in 32 bit mode" what does this mean and how can I fix it?

I keep getting message "This page requires a plugin that can only run in 32 bit mode" what does this mean and how can I fix it? It seems to come up randomly, but I'm fairly ignorant.

Previous versions of Firefox were only 32 bit, Firefox 4 for the Mac contains 32 and 64 bit versions. If you want to always start Firefox in 32 bit mode, open up Finder and go to the Applications folder. Control-click the Firefox app and click "Get Info", then select the "Open in 32-bit mode" option.
