  • How to avoid "Page Expired" messages on logout with Wicket after redirect

    - by John
    Hi there. I'm taking my first steps in to the world of Wicket. I've set up a login form and a logout page. The logout page looks like this: public class LogoutPage extends WebPage { public LogoutPage(final PageParameters pageParams) { getSession().invalidate(); setResponsePage(getApplication().getHomePage()); } } When a user clicks the Logout link they're redirected to the homepage, so far so good. The problem is that when a user tries to click on any of the navigatable Link's they get a "Page Expired" message. I'd like to log the user out gracefully and allow the user to continue to browse the website without receiving the "Page Expired" message. Any help is greatly appreciated. By the way, I've tried to follow the Wicket examples but they seem to be using org.apache.wicket.authentication and I haven't figured out how to make this available to my project (I'm using eclipse and maven2).

  • How to get rid of Thunderbird error "[NONEXISTENT] Unknown Mailbox: Trash"

    - by endolith
    Every time I start Thunderbird, I get this error: The current operation on 'Trash' did not succeed. The mail server for account [email protected] responded: [NONEXISTENT] Unknown Mailbox: Trash (now in authenticated state) (Failure). I've figured out that it goes away if I create folders in my Gmail accounts called "[Imap]/Trash" and "[Imap]/Sent", but why are these necessary? Even if I tell Thunderbird to unsubscribe from them, it still notices when I remove the labels and starts popping up this error again. One account also complains if I remove the "Sent Items" label.

  • OSX esc key stops working (randomly)

    - by Jan Hancic
    I have a 2011 macbook Air with OS X Mountain Lion (I've upgraded from Lion). And ever since upgrading my escape key randomly stops working. And it's not that the keyboard on the laptop would be damaged as the same happens if I use apple's bluetooth keyboard. So I'm guessing it's a software issue. Also in some cases pressing ctrl+esc achieves the same thing as just esc so I'm 100% it's not a hardware problem. Does anybody have any idea what this might be all about and how to fix it? edit: the escape key stops working completely but it starts working again after I restart the computer. edit2: this usually happens after the computer wakes from sleep. So it's not like that is just stopps working in the middle of using it, but rather after I put it to sleep (or just close the lid) and then open it again. Has nobody got the same issue? Is there a better place to ask OSX related questions than SuperUser maybe?

  • Enable VT-x in HP 8300 elite

    - by lang2
    I have a HP 8300 elite (Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz). I'm trying to run a virtual machine via VirtualBox. But every time I start the VM, it says: VT-x is disabled in the BIOS. (VERR_VMX_MSR_VMXON_DISABLED). My lscpu output is like this: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 2 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 58 Stepping: 9 CPU MHz: 1600.000 BogoMIPS: 6784.74 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 8192K NUMA node0 CPU(s): 0-7 I went into the BIOS but the things the can be tweaked is very limited and I couldn't find the VT-x setting. Anybody know how to do this in this setup?

  • free open-source linux screenshot & ocr tool

    - by Gryllida
    I'm looking for a tool which would be able to capture a screen region, pass it to OCR and put the result into clipboard. "import ppm:- | gocr -i - | xclip -selection c" works, but gocr is unreliable: simple text on a webpage has errors. It is a clear font but the OCR tool always misses "r" and replaces it with underscore. "import ppm:- | ocrad -i - | xclip -selection c" says "ocrad: maxval 255 in ppm "P6" file." tesseract needs an image file and does not accept piping input to it. xfce4-screenshooter does not do OCR. ABBYY Screenshot Reader is proprietary. tessnet2 is freeware running on a proprietary platform. Google Docs can OCR screenshots in a batch. But my data is confidential and better not put online. Graphical interface solutions would be acceptable for this question, too. There is a number of existing SuperUser questions about OCR. They fall in several categories. Questions just about OCR without the "screenshot taking" part. Open Source OCR for linux Free OCR for Arabic text Looking for recommendations on OCR problem - tabular numeric data Which has better OCR applications: Ubuntu, or Mac/iPad, or Windows? How can I preform OCR from the command line? OCR solution on linux machine from command line (duplicate) Free OCR software OCR for Sanskrit ( OR devanagari) Copy image and paste to OCR (windows) File processing OCR instead of screenshot.

  • Google chrome asking for username and password for OWA

    - by Grant
    Hi, i have a question about the google chrome browser. When i navigate to my work's Outlook Web Access site to read my emails, the chrome browser is prompting me for a username and password to the server saying "Authentication Required - the server XXXXXX.XXX:443 requires a username and password. After i put them in i then have to enter in the normal OWA username and password to access my emails as per normal. The funny thing is.. 1] If i click CANCEL on the first dialog it takes me to the OWA screen and i can log in normal anyway. However - subqeuent page clicks will keep prompting me each time for the server credentials. 2] I am NOT prompted for server UN and PW if i use IE or fireFox. Does anyone know how to stop chrome from asking me each time? or is it a server setting - i do know that a friend who uses the same browser (chrome) and also OWA does not have the same problem (NB: they work at a different company) Thanks!

  • Fixing windows MBR without Vista Recovery CD

    - by Aditya Sehgal
    I had Windows Vista + Ubuntu running on my system. I deleted the ubuntu partitions from Windows. However, when I start the system, GRUB throws up an Error 22 (missing partition) and does not let me boot into Windows. The CD ROM on my laptop is fried and therefore I tried installing Ubuntu again using a USB install. However, the version Ubuntu 9.10 justs hangs in the load screen and does nothing. I do not have windows Vista Recovery CD (as it was a recovery partition in my laptop). What are the options I have? How do I fix this?

  • How to calibrate monitor colors to use 3D glasses?

    - by GetFree
    I have a pair of red/cyan 3D glasses and when I use them to view youtube's 3D videos or anaglyph images they dont seem to work properly. The two images are not filtered properly by each colored lens. So I guess the problem is my monitor not showing the exact colors needed for my glasses to work. Is there any way to customize/calibrate the monitor's colors for a specific pair of 3D glasses? PS: I also have green/magenta and amber/blue glasses, but the same problem happens.

  • MP3 fingerprint tagger

    - by droberts
    Does anyone know of a tool which will read mp3 audio information directly (not the tag information), generate a fingerprint of that audio information, recommend tags based on the fingerprint and retag your MP3 collection? Last.FM released a console application which did all but retag your collection.

  • Cache Refresh in Chrome

    - by gAMBOOKa
    I dunno what exactly it's called, by cache refresh I mean, refresh the page after clearing its cache. I don't want to clear the entire browser cache. I prefer Chrome's Dev panel against firebug... don't ask me why. But I can't seem to cache refresh my pages. In FF, I know it to be Shift+Refresh. In chrome, I've tried Ctrl+R, Ctrl+Refresh, Alt+Refresh, Shift+Refresh but none of them work. EDIT: I got a Notable Question Badge for the lamest question I've ever asked. FML.

  • How does a hard drive compare to Flash memory working as a hard drive in terms of speed?

    - by Jian Lin
    Some experiment I did with hard drive read/write speed was 10MB/s write and 40MB/s read, and with a USB Flash drive, it can be 5MB/s write and 10MB/s read. Also, if I put a virtual hard drive .vhd file in a hard drive or in a USB Flash drive and try a Virtual Machine using it, the one using the hard drive is quite fast, while the one using the USB Flash drive is close to not usable. So I wonder some early netbooks use 4GB or 8GB flash memory as the hard drive, and even the Apple Mac Air has an option of using flash memory instead of a hard drive. But in those situation, will the speed be slower than using a hard drive, like in the case of a USB Flash drive?

  • Wacom consumer tablet driver service may crash while opening Bamboo Preferences, often after resuming computer from sleep

    - by DragonLord
    One of the ExpressKeys on my Wacom Bamboo Capture graphics tablet is mapped to Bamboo Preferences, so that I can quickly access the tablet settings and view the battery level (I have the Wireless Accessory Kit installed). However, when I connect the tablet to the computer, in wired or wireless mode, and attempt to open Bamboo Preferences, the Wacom consumer tablet driver service may crash, most often when I try to do so after resuming the computer from sleep. There is usually no direct indication of the crash (although I once did get Tablet Service for consumer driver stopped working and was closed), only that the cursor shows that the system is busy for a split second. When this happens, the pen no longer tracks on the screen when in proximity of the tablet (even though it is detected by the tablet itself); however, touch continues to function correctly. To recover from this condition, I need to restart the tablet driver services. I got tired of having to go through Task Manager to restart the service every time this happens, so I ended up writing the following command script, with a shortcut on the desktop for running it with elevated privileges: net stop TabletServicePen net start TabletServicePen net stop TouchServicePen net start TouchServicePen Is there something I can do to prevent these crashes from happening in the first place, or do I have have to deal with this issue until the driver is updated? Windows 7 Home Premium 64-bit. Tablet drivers are up to date. Technical details Action Center gives the following details about the crash in Reliability Monitor: Source Tablet Service for consumer driver Summary Stopped working Date ?10/?15/?2012 2:48 PM Status Report sent Description Faulting Application Path: C:\Program Files\Tablet\Pen\Pen_Tablet.exe Problem signature Problem Event Name: APPCRASH Application Name: Pen_Tablet.exe Application Version: 5.2.5.5 Application Timestamp: 4e694ecd Fault Module Name: Pen_Tablet.exe Fault Module Version: 5.2.5.5 Fault Module Timestamp: 4e694ecd Exception Code: c0000005 Exception Offset: 00000000002f6cde OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: 9d4f Additional Information 2: 9d4f1c8d2c16a5d47e28521ff719cfba Additional Information 3: 375e Additional Information 4: 375ebb9963823eb7e450696f2abb66cc Extra information about the problem Bucket ID: 45598085 Exception code 0xC0000005 means STATUS_ACCESS_VIOLATION.

  • How is this word document encoded?

    - by Steven Lee
    Hi all, We have a program that was written for us by a developer that we can no longer contact, the program opens word documents (forms) that we use in our company, you can tell they are Word documents as the 'Word' toolbar displays with this custom program and we can see the .doc files on the hard drive, the Save button is disabled in the program and when we open the .doc files in word the encoding is not standard as the forms are unreadable but look perfect in the custom program. If we can word out how he has done this we can hopefully convert the 100's of forms that we use. One of the .doc files can be download below, I've scanned it for viruses, it's clean. If anyone can tell me how we can fix this I'd be very grateful. http://www.2shared.com/document/Vb06LUmP/C4-002_Amenity_Fund_Constituti.html? Many thanks Steven

  • QoS for Cisco Router to Prioritize Voice and Interactive Traffic

    - by TJ Huffington
    I have a Cisco 891W NATing Voice and Data to the internet over a 10mbit/2mbit connection. Voice traffic gets degraded when I upload large files. Pings time out as well. I tried to configure a QoS policy but it's basically not doing anything. Voice traffic still degrades when upload bandwidth gets saturated. Here is my current configruation: class-map match-any QoS-Transactional match protocol ssh match protocol xwindows class-map match-any QoS-Voice match protocol rtp audio class-map match-any QoS-Bulk match protocol secure-nntp match protocol smtp match protocol tftp match protocol ftp class-map match-any QoS-Management match protocol snmp match protocol dns match protocol secure-imap class-map match-any QoS-Inter-Video match protocol rtp video class-map match-any QoS-Voice-Control match access-group name Voice-Control policy-map QoS-Priority-Output class QoS-Voice priority percent 25 set dscp ef class QoS-Inter-Video bandwidth remaining percent 10 set dscp af41 class QoS-Transactional bandwidth remaining percent 25 random-detect dscp-based set dscp af21 class QoS-Bulk bandwidth remaining percent 5 random-detect dscp-based set dscp af11 class QoS-Management bandwidth remaining percent 1 set dscp cs2 class QoS-Voice-Control priority percent 5 set dscp ef class class-default fair-queue interface FastEthernet8 bandwidth 1024 bandwidth receive 20480 ip address dhcp ip nat outside ip virtual-reassembly duplex auto speed auto auto discovery qos crypto map mymap max-reserved-bandwidth 80 service-policy output QoS-Priority-Output crypto map mymap 10 ipsec-isakmp set peer 1.2.3.4 default set transform-set ESP-3DES-SHA match address 110 qos pre-classify ! fa8 is my connection to the internet. Voice traffic goes over a VPN ("mymap") to the SIP server. That's why I specified "qos pre-classify" which I believe is the way to classify traffic over the VPN. However even when I ping a public IP while saturating upload bandwidth, the latency is exceptionally high. Is this configuration correct? Are there any suggestions that might make this work for my setup? Thanks in advance.
