We should NEVER use the session back bean?
Because the user can open a new window by right click the link, and the session scope back bean is not thread-safe.
So we should forget it?
Your concern makes really no sense, or you must be storing request scoped data in a session scoped bean instead of a request scoped bean, which can indeed lead to undesireable behaviour in multiple requests on the same session.

May i use the session bean like this, if i dont want to use the data access object
may i use this...Hey it apperars to me like heero82 is using session facade and all he has to do is use session bean to make one business call on session bean. Now if u say it is not correct then i would like to know the better way to doing so.
I can imagine one ways is use business delegate. Just make new of java class in jsp and let that java class do lookup and delegate the call to session facade.
Let me know inpout on this

I have an Ipad first generation with IOS 5.1.1. and I have just got a new ipad mini. Should I use the back up copy of the old Ipad from Itunes to configure the new one, or it is better to configure the new one from scratch?
Contrary to the opinion above, I see no reason whatsoever why you can't set up the new iPad from the backup of the old one. Obviously you will have app updates to make and complete and that sort of thing, but if you want to retain all of your app data and device settings (some of which will change because of the updated iOS), I would certainly restore from the backup first.
If you find that to be problematic, you can always start all over again. -
ADF BC how to access session backing bean value in servlet
Hi everyone,
How do I access session backing bean value in a servlet?Frank, thanks for your reply.
I'm not sure how I can incorporate this example into my situation. Let me explain more detail about my problem.
"servlet" in my post here actually means a custom servlet I wrote for rendering an image that is stored in db as ordimage. In this servlet, I get hold of my appmodule by using Configuation.createRootApplicationModule(). By doing so (If I'm not wrong) a new database session/connection is created. What I'm going to achieve is set application context for this new session/connection in db with the data stored in a session backing bean in the view layer.
I can pass the required data to the servlet thru url parameter, but I don't want to do it this way for the reason that the data may contains sensitive information.
I hope I have explained myself well.

We have 4 iphones and an Ipad in our family. When we purchase music, I would like for the entire family to be able to use it and then back it up to Icloud. What is the best and cheapest way for this to happen. Should we all have a different apple id or should we use the same one.
You will all need to be on the same itunes account ID.
You can however all have seperate icloud accounts aswel. -

I had tried using -Xms / -Xmx options (upto 1 GB).
The trace of exception gets delayed (from being displayed on the console) as the memory size is increased; but after sometime it starts getting displayed on the console.
Even though this exception is displayed on the console, the Timer Bean continues to execute upto sometime before it finally crashes!
If anyone has encountered such problem; would appreciate if you could share the solution.
Regards, VidyadharHi guys, I have the same problem. I have an application EAR file with two modules (EJB and WAR starting in this order). The application can schedule a process via EJB timer. In this case restarting the server I receive the error above. If I change the modules start order --> WAR - EJB the server start correctly, but the application scheduler fails (the persistency is not working) with this error:

Any idea?

Since I've updated from iOS 5 to iOS 6 I am unable to use the next/back buttons from Headphone for audio book chapters.
This is working fine for albums but are broken for audio books.
The back button refers always to the first chapter of the audio book (very annoying if you are in the middle of an audio book) and the nex button goes one level higher back to the selection of the audio book itself.
In iOS 5.0 it was still possible to navigate throught the audio book chapters using these buttons.
This still happens in iOS 6.1.
Is this a known bug?
Does any solution exist?
Thx,
OliverTo gdgmacguy your a f****** idiot for one I'm having the same problem as pennymar. And you tell me to quit whinning. You got more problems then the iOS 6 you did not answer my question nor the other 13 or whatever you replied to within a 30 min time frame. You must got nothing better to do then to harass people and to pretend you know something about apple products. Which you don't from what I've read the other advices you should have gave to other people. But you didn't you replied a question back to the people asking a question. So if your not gonna use these community forums the right way don't use them at all.

My 2011 MBP has begun running slow with frequent 'spinning beach ball' events. I'm running Yosemite and wondered if I should of use the original install disk for a maintenance reinstall. I presume I'd have to download Yosemite again, though I'd be happy just using Snow Leopard again too.
Thanks for the help.When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.

I have an apple id for my ipod touch at home. My company is planning to issuing Ipads. Should I use the same apple id on the ipad for those apps I purchase and would like to use on my work ipad?
Yes, otherwise you will have to pay for those apps again. If an app is purchased by one Apple ID, he/she will be able to redownload it again for no cost (note: this does apply to songs, but NOT to movies).

How to use the Dynamic Configuration Bean
Hi experts,
im currently doing a file to mail scenario.
i want the name of the input file as the subject of the mail.
i want to establish this using the Dynamic Configuration bean
my first question is:
key.1 <b>read</b> http://sap.com/xi/XI/System/Mail THeaderSUBJECT
value.1 message.messageID
this reads the value of the message ID into the attribute THeaderSUBJECT
but what does this do?
key.1 <b>write</b> http://sap.com/xi/XI/System/Mail THeaderSUBJECT
value.1 message.messageID
when i use this it has no effect atall.
my second question.
I have my input filename in the FileName attribute in Dynamic configuration how can i read it into THeaderSUBJECT attribute.
Appreciate any suggestions.Hi Satish,
Yep i know its possible via an udf in Message mapping but i dont have an MM in my scenario. Since im not parsing thru the input data since its an excel file, so im transferring the file using the following method
/people/william.li/blog/2006/09/08/how-to-send-any-data-even-binary-through-xi-without-using-the-integration-repository
and in this method if i include an MM it will give me a mapping exception.
So i have to use this bean somehow and try to accomplish what we do in the udf. -
Should I use the fine-grained auditing?
I need to record the changes (of data) made to serveral tables by users. For example, I have to check the before and after images of the changes and what kind of transactions they do to cause the changes. Sould I program the logging procedure in the application or should I use the fine-grained auditing function of oracle to do it. I am not sure what this built-in function can do for me. Can anyone give me some advice on this? Thks.
A beginnerWhy Fine-Grained Auditing?
You may want to check standard auditing if it is suitable for you
http://download.oracle.com/docs/cd/B19306_01/network.102/b14266/cfgaudit.htm#BABCFIHB
I don't think you can get pre and post update values of the affected data with Auditing.
FGA is useful when you want to audit just a "subset" of the data in the table.
(for instance, audit everyone that wants to get all records from EMP table where SALARY > 100000)

Should i use the same pass words on my macbook that i use on my ipad?
HI...I have 2 questions...I am thinking about buying a macbook pro and when I set it up...should I use the same apple ID as I use on my ipad?
Then...does the macbook pro have Java and Flash Player so I can play all the Pogo games?You should use the same Apple ID. The same Apple ID must be used in all your devices in order to sync data through iCloud and get the purchases you make in all your devices, for example. Also, you can register your devices to your Apple ID, receiving a better support if you have any problem.
The MacBook Pro is compatible with Java and Flash Player, but it doesn't come with them preinstalled. To install Flash, visit the Adobe site > http://get.adobe.com/flashplayer Respecting to Java, OS X will ask you to install it when you want to play Java content
