When do we use SingleThreadModel ?

when do we use SingleThreadModel of Servlet ? Is there any practical situation where this could be used ?

I think there are specific requirements that would need the SingleThreadModel just like there will be need for Singleton classes. An example is the Event Dispatch Thread used in swing.Err, no. This is complete nonsense. SingleThreadModel is an interface in the Servlet API. Servlets don't use Swing.
@OP: SingleThreadModel is 'deprecated as of Servlet API 2.4, with no direct replacement'. That was in 2004. So the answer is that you don't use it at all.

how can i stop an error message that comes up when i am using word? the error message is "word is unable to save the Autorecover file in the location specified. Make sure that you have specified a valid location for Autoreover files in Preferences,…"

It sounds like if you open Preferences in Word there will be a place where you can specify where to store autorecover files. Right now it sounds like it's pointing to somewhere that doesn't exist.

No PDF created when section break used and no data in XML group

I have this issue that Tim Dexter documented on a few years back...
http://blogs.oracle.com/xmlpublisher/output_formats/
"When you are using @section in your template for the commands, 'for-each' or 'for-each-group' (e.g. <?for-each@section: ...?>), then an empty/invalid PDF can be generated if XML data file has no data for that for-each loop."
This is my exact issue. Yet the instructions do not solve my problem completely. I add another section break at the end of my RTF and it gets the page to show...but I get an extra page at the end of all the populated xmls
Is there a way to supress this page?

Hi Jason,
I would like to see your template and data.
You have use @section and add condition to make the no-data page.

How do I put an external display to sleep when I am using my MacBook Air for presentation?

How do I put an external display to sleep when I am using my MacBook Air for presentation? I do not want to go to the projector just to turn it off and turn on again after a while? Is there a keyboard shortcut for that?

I want to be able to sleep the external display and at the same time do things in the MacBook.( This feature is useful for me so that I can prepare some things and so that my audience will not see what I am about to show them.)
Is there a feature for Mountain Lion?

When I am using the browser for a while and try to use ANY search bar and hit the "search" button it does a whopping NOTHING is there anyway of keeping this from happening?

Whenever I am using Firefox mobile - either regular, beta or aurora and go to search for something like through the Google search page and attempt to search for something the search bar does nothing and hitting the enter button instead doesn't do anything either. Is there a way to keep this from happening?

Hi and thanks to not leaving the firefox user alone.
Cor-el your answer is right as the madperson is and I already knew all these
answer and I said that before I don’t use any antivirus and I always turn off my firewall from the moment I installed my Windows.
I even turn off any automatic update for any of my software and I never let any unknown plugins or any thing like that be install without informing me. And if you know some things like Offline Storage and cookies must be to much more than usual and you have to clear them and delete them and I know so much more
And if you want to know it fixed now. But I don’t know how?
For understanding my problem read and research about Ixplorer.exe virus it is the same problem about the speed but the different is it doesn’t show any process in task manager like Ixplorer.exe virus
Bt I have done some things but still I don’t know that’s why it is fixed or not
First: I searched my system and removed any files have been crated on my system from two days ago since the problem happened.
And then I used to go about the article in this page and did like this:
http://answers.yahoo.com/question/index?qid=20080910101846AAazxN5
but still I don’t know any thing about the problem.
I can do so many things to fix but I am just curios if that is a virus why it just cut the speed when I am using the browser.
Please if any one found the reason send me your information I like to know it will improve my knowledge however my problem is solved fro now.

Problem when try to use ACSE+ Windows AD to authenticate two kind of WLAN c

I met a problem when try to use ACSE+ Windows AD to authenticate two kind of WLAN clients:
1. Background:
We have two WLAN: staff and student, both of them will use PEAP-MSCHAPv2, ACSE will be the Radius server, it will use Windows AD's user database. In AD, they create two groups: staff and student. The testing account for staff is staff1, the testing account for student is student1.
2. Problem:
If student1 try to associate to staff WLAN, since both staff and student WLAN using the same authentication method, the auth request will be send to AD user database, since student1 is a valid user account in AD, then it will pass the authentication, then it will join the staff WLAN. How to prevent this happen?
3. Potential solution and its limitation:
1) Use group mapping in ACSE(Dynamic VLAN Assignment with WLCs based on ACS to Active Directory Group Mapping), but ACS can only support group mapping for those groups that have no more than 500 users. But the student group will definitely exceed 500 users, how to solve it?
2) Use methods like âRestrict WLAN Access based on SSID with WLC and Cisco Secure ACSâ: Configure DNIS with ssid name in NAR of ACSE, but since DNIS/NAR is only configurable in ACSE, don't know if AD support it or not, is there any options in AD like DNIS/NAR in ACSE?
Thanks for any suggestions!

I think the documentation for ACS states:
ACS can only support group mapping for users who belong to 500 or fewer Windows groups
I read that as, If a user belongs to >500 Windows Group, ACS can't map it. The group can have over 500 users, its just those users can't belong to more than 500 groups.

Having a problem with commandButton attribute when i am using it under tabl

<h:commandButton action="#{createTransaction.transactionCommand}" styleClass="tixbutton"
value="#{labels.SUBMIT}" actionListener="#{createTransaction.processAction}">
<f:attribute name="dbName" value="#{wlmHandler.dbName}"/>
<f:attribute name="plexName" value="{color:#ff9900}#{onePlex.name}"{color}/>
</h:commandButton>

PS CS5 Extended on Windows
When trying to use the clone stamp and/or healing brush as soon as I move the cursor from the toolbar over to the image I get an exact copy of the existing layer that moves around the window with the movement of the clone stamp/healing brush. This just started tonight. What's causing this weird behaviour?

When I am using Premiere elements 13 I get a message that pops up "that there is no disk in the drive. Please insert a disk into drive", this also happened 3 months ago How can I get rid of this again?

When I am using Premiere Elements 13 I get a message that pops up "There is no disk in the drive" I click on it and it keeps coming back "very annoying", but about three months ago it happened to me and I was told to change the file name from OldFilm.AEX to OldFilm.AEXold. Well now the file is back in Folder OldFilm.AEX. Here is a screen shot the files are highlighted.What should I do now to correct this once and for all, or can I? Thank you for your time.

TomWolves
I would do another rename to disable or just delete all the OldFilm.AEX and OldFilm.AEXOLD in that NewBlue Folder.
If you do, please let me know if that OldFilm.AEX regenerates itself the next time you open Premiere Elements 13.
Here is the strange story...at least from my Premiere Elements 13 Windows perspective...never had the No Disc error issue
Here are some details to sort through trying to figure out why you have 2 OldFilm.AEX file in the NewBlue Folder.
1. The original OldFilm.AEX file of Premiere Elements 13 has the date of 9/4/2014 (just before the version was released on 9/24/2014).
After the 13.1 update is done (whenever date), that OldFilm.AEX file has the date of 1/31/2015. I first saw notification of the 13.1 Update
release early in February 2015.
2. Now in Premiere Elements 13.1, if I take my OldFilm.AEX (date 1/31/2015) and disable it by renaming it to OldFilm.AEXOLD, close out of there, and reopen
the program, the OldFilm.AEX is not seen to regenerate. The OldFilm.AEXOLD remains there as its lone self.
3. So, I am thinking that your OldFilm.AEXOLD in the screenshoot is "original equipment" that you disabled to get rid of No disc error.
Why the OldFilm.AEX is there also is not clear, but the dating on it suggests that it came along with the 13.1 Update.
Bottom line: let us try the deletion or disabling one more time and see what happens.
Looking forward to further reports on your findings, as your time permits.
Thanks.

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

How do I delete an old Apple ID and still update apps purchased when I was using it?

How do I delete an old Apple ID and still update apps purchased when I was using it?

One, you cannot delete an Apple ID, all you can do is stop using it and let it fade away.
Two, apps are permanently tied to an aPple ID and can never be transferred to another. You must use that same ID to update an app, or delete the app and repurchase/download under another ID.

I want to play music from my playlist when I am using slideshow of my pictures in Ipad, but I can only choose ONE SINGLE song, and it continuously repeates itself. Is there a way to play the complete playlist while showing my pictures?

I want to play music from my playlist when I am using slideshow of my pictures in Ipad, but I can only choose ONE SINGLE song, and it continuously repeates itself. Is there a way to play the complete playlist while showing my pictures?

You can start the playlist playing in the iPod app and then switch into the Photos app and start your (non-music) slideshow - as you've found out you can currently only select a single track in the Photos app. Whether that will change in iOS 5 I don't know, but you could try leaving feedback for Apple : http://www.apple.com/feedback/ipad.html
