HELP: jsp:useBean not "working"

I have written a JSP that utilizes some JavaBeans. With one, I do something similar to the following:
<jsp:useBean id="BeanA" class="mypackage.myFirstBean" />
That statement executes just fine, as the debug HTML statement that follows is printed using <c:out>.
Then I follow that with something nearly identical:
<jsp:useBean id="BeanB" class="mypackage.mySecondBean" />
The debug statement after this second <jsp:useBean> call is not executed.
The two beans have no-argument constructors and are in the same package, and both are found in the right hierarchy under WEB-INF/classes inside my WAR file. Also, both are named properly in the JSP. The only difference is that one "executes," and the other does not. I don't even get to call <c:set> on them to actually make them do some work!
Any insight is appreciated. Let me know if there is anything else I can provide.
Thanks for your help, and Happy New Year!

The symptom you described is certainly curious.
Can you put the second "useBean" line before the first one? Then please tell us if it "executes".

HP-2840 needs new drum (Q3964A) and I am told my printer will not work when I install a new drum

My HP2840 laser jet All-InOne has been telling me for 6 months that I need a new drum. I was waiting until I saw an issue with my print quality (which I never had a problem) and now my printer will not work unless I replace the drum.
A friend told me that even after installing a new OEM drum, that my printer will still not work unless I call HP and pay for them to tell me how to make it work.
Is that true?
I need help fast cause now my wife is really angry that I "broke" the printer!
Thanks in advance!

Bootcamp assistant not working when clicking install

Trying to use bootcamp assistant, on the partion disc screen, i select the partition size but the install button wont do anything when clicked.
It just stays on the same page and no message comes up, anyone got any thoughts?

I think you need double quotes rather than single.. as in
new URLRequest( 'PDF_FILES/1. MD&A Introduction.pdf' );
try
new URLRequest( "PDF_FILES/1. MD&A Introduction.pdf" );
also the file names are a little odd.... there is a space after the period 1. (space here) MD...this will present problems once on server.
And then you have an ampersand in the file name..... while that may work, sometimes servers are much more particular.... things like spaces and special characters in file names can cause problems.
One recommended method of naming files and folders is:
All lower case (no caps)
No_spaces_use_underscore_instead
No special characters

Auto updates for VSTO addin not working that was installed using MSI

I am not a .NET guy so this might be naïve question.
We have developed an MS Excel VSTO add-in using Click-Once (VB .NET). Due to some business requirements, We packaged that add-in as MSI.
DEVENV excel-addin.sln /Project AddinSetUp\AddinSetUp.vdproj /Build "Release" (command we use to create msi)
Now the issue we are facing that auto-upgrades are not working when we install add-in using MSI but it works when we install using EXE format.
Are we missing something during build?
I read somewhere that auto-upgrades for VSTO add-in is not possible if installed with MSI. is it the case?

Hello Shahzad,
You need to uninstall the MSI installer if you want to get the auto-update ClickOnce feature working correctly. You can read more about MSI and ClickOnce installers in the following articles in MSDN:

I just installed Photoshop CC 2014, but Latest version of Bridge will not work when I want to open it from PS

Any idea why is Bridge latest version not working when trying to open it in Photoshop CC 2014 ? (French version) ? When trying, Creative Cloud app will open to ask if I want to download newest version, which I did numerous times now.
Thank you

Hi Eric,
Here's how a similar problem was resolved between PS and BR.
The issue was confirmed by ChunXiaYang at Adobe staff and solution put in the forum discussion on June 19 (no. 13). Here's a copy:
I have confirmed that this is a known issue before release. And the workaround is to uninstall and reinstall PS 2014. Then Bridge can be launched by selecting 'Browse in Bridge' in PS2014.
Please try the installation, and let me know whether it works. Thanks!
It woks just fine since I unistalled and reinstalled PS 2014.

I did this with a fresh install of the entire CC package. As soon as the CC packages updated, CC Bridge broke. Unistalled CC PS, reinstalled again, CC Bridge works, but CC PS updates itself again, and breaks CC Bridge.
You know... The whole move to CC has been a massive cluster... I've struggled with the CC packages for my entire subscription year, and now I'm 1.5 month away from needing to throw down another $720 for no reason what-so-ever, just so we can Beta test your really screwed up subscription services.

Bean in JSP is NOT WORKING. Please help

Hi,
          Anyone who got java-beans working with WL JSP? I could not get even the
          hello bean to work. I am getting a error message saying somthing like
          "foo.bar.HelloBean.class is not a bean" .
          Is there any perticular reason for the abuse of not including java bean
          example in JSP examples?
          I will greatly appreciate any help in this direction.
          Thank you in advance
          -Harit


If I had to guess based on the error message I would say you have incorrectly
          defined the class file.
          Remove the .class from the definition within the JSP.
          For instance,
          <jsp:useBean
          id="myHelloBean"
          scope="session"
          class="foo.bar.HelloBean">
          </jsp:useBean>
          Not class="foo.bar.HelloBean.class"
          Hope this helps.

Thunderbolt ethernet not working when computer wake up from sleep.

thunderbolt ethernet not working when computer wake up from sleep.
it will not happen in Mountain loin.

I had this problem on SL and on Lion as well, and it occures for WiFi and Ethernet connections.
In fact the internet connection was not broken as I could ping the destination usin the IP (not DNS name).
In this case the problem was related to mDNSResponder task which handles all dns queries.
It was the most frequent problem in my day to day work with SL and now Lion. It was never fixed by any patch from Apple. I tried almost all voodoo including fresh install, all possible config changes - no solution.
The only version with no problems related to network was 10.5.8. All the other versions had issues of different kind (WiFi instability (lost signal), DNS problems (for wireless and wired connection) sometimes associated with machine sleep and wake up and sometimes with no reason.
QUESTION: Is your problem independent of the access point / router you connect to.
I must say networking was (and still is) the weakest part, besides the other OS X weaknesses I experienced during 4 years of OS X usage.
No problems in the same network with Linux or Windows beeing ran natively on my iMac So hardware is OK.
Software is of poor quality. Not much more to say in this matter.
I found a very interesting article dated 1996 about programming which I think is still valid.
Link to the article: http://www.fastcompany.com/magazine/06/writestuff.html

It means, tentatively, that system files are missing or damaged and you will have to reinstall Snow Leopard. See the following:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. 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 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

Security and privacy system preferences not working after Lion install. What to do?

Security and privacy system preference not working after Lion install. Not sure if it happen with Lion installer or after updating. What to do?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” (without the quotes) and press return. You should then get a new line ending in a dollar sign.
Step 1
Copy or drag — do not type — the line below into the Terminal window, then press return:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.) You can omit the final line ending in “$”.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

HEADPHONES do not work when plugged in - iMac Intel

So I reinstalled the operating system a few months back. After completing this my headphones do not work when plugged in. I do have them plugged into the correct jack. When i plug them in the built-in speakers go silent for a second or two as if the headphones are working but then the speakers kick back in with no sound in the headphones.
The headphones worked just prior to reinstall so I'm not sure its the jack itself but something in the operating system.
I have also checked in System Preferences 'Sound' and when they are plugged in, they do not show in the devices window.
What the heck is going on? I've read in other forums that this seems to be something of a typical problem but have not found a solution to the problem.
thanks in advance for your help.

Welcome to the discussions.
Mate, it sounds more like a system glitch than a hardware issue. I too have been experiences some 'funky' issues. However, they have all been fixed by running Onyx disc maintenance software. Install Onyx and run 'automation'. You can cancel the disc checking operations on start up and ignore the back up disclaimer. Give it a go and post back with the results.

Speakers Not Work When Diplay is in Upright Position - Lenovo G450

I have a Lenovo G450. Recently the built-in speakers will not work when the display monitor is in open position. The speakers will work when display monitor is half closed. How can I fix this problem?
Thank you for any help you can offer to me in solving this problem. ..

The speaker is installed at the bottom of the notebook please make me correct if it is on Display Panel.
Make sure you have the updated Audio driver and BIOS.
Please refer to the web link http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=370748
You may also connect the external speaker and check if the same issue appears.

Microphone not working when using a phone call, Microphone not working when using a phone call

Microphone is not working when i use my iphone 4, first day when i installed a iOS 7 , was all good, second day this happened. Please help me. When i use a Viber microphone working. I think this is not a hardwear problem.

Hi Mike
That was very helpful thank you.
I did as you suggested and found the "switch" was already turned on green. I swiched it off waited a while then turned it back on and microphone was back in use in viber. I have a sneaky feeling I may have to do this again in the future. I am not aware that I did anything that led to the microphone going off, but having said that I have only had the phone for a few days so may have done something when checking it out.
The phone has been a lot of fun after replacing my ancient Nokia with it. That Nokia worked in Morse code!
Best wishes

Keyboard backlighting not working when using Windows in Boot Camp

Hi, I'm posting this for a friend with a new Macbook Air. He says that his keyboard backlighting does not work when he is using it for Windows (don't know which, but probably Vista). Any ideas why? Thanks. Gary

Install all the drivers needed when running boot camp - try for example inserting a DVD - then press the eject key - See if it comes out - If it doesn't install all the drivers - try Control Panel - If not try re-installing your version of Windows.
