Error "Timer already cancelled" when you use CFIMAGE - captcha

I've implemented the captcha image using cfimage. Works very well on our system of development, however, I'm a "java.lang.IllegalStateException: timer already cancelled ' in our production environment."
The first time I asked the page containing the image captcha took forever to load but eventially made. Subsequent requests for this page now produces the above error. Production environment is running Coldfusion 8.01 in multiserver with last fix applied, IIS 6 configuration.

Solved the problem! It turns out that simple restart the CF service solves the problem.

  • error: "cannot find symbol" when you use String.getBytes (java.nio.charset.Charset)

    I have a very simple java class that uses String.getBytes (java.nio.charset.Charset). When I use loadjava, I get the error: "cannot find symbol" for this call. Any ideas on what could be the problem?

    Your code is correct for java 1.6 and higher...

    First of all, you should check that java version is on your database...

    FUNCTION to CREATE or REPLACE getJavaProperty (myprop IN VARCHAR2)

    RETURN VARCHAR2 IS THE JAVA LANGUAGE

    name "java.lang.String return java.lang.System.getProperty (java.lang.String);

    SELECT getJavaProperty ('java.version') of double;

    in my case, I have java 1.5...

    If you look at the Javadoc String (Java Platform SE 7) you will notice that your version is located for java greater or equal to version 1.6

    Try with:

    CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED INSURANCE2."Test1" as
    public class MyTest
    {
    public static int printString(String s)
    {

    Do you have other accounts of users on this PC?  If you install this update from the main account?

    You should get the number of the update of the updated history list and then download the file here: Microsoft downloads.
    If sure that nothing else is running, and then install the update manually.  Give it a try and let us know the results.

  • I keep getting out of memory errors when you use Windows Media Player.

    original title: of memory error

    Hi, I have a Windows 7 PC brand new with 12 GB of RAM, but I get low on errors of memory, especially when you use Windows Media Player. I tried:

    -Execution of the antivirus scans

    -Cleaning things out of the startup folder

    -Increase in the size of paging file

    I can't understand what the devil is the cause of this error - as I said, it's a new machine, and is not practically nothing on it yet.

    Any help is appreciated.

  • When you use the Windows XP Mode integration, it fails; maintains a new attempt and finally I have to cancel

    When you use the Windows XP Mode integration, it fails; continues to try again and finally I cancel it. The same newspaper for Virtual PC on the host computer has the following error message: Windows XP Mode integration error 'failed to connect in place inside the "Windows XP Mode" VM on channel 0 on the... named pipe endpoint XP, TCP port 3389 with the 0x8007274c error mode. This error occurs every time, but I don't know why he is successful a few times and sometimes fails. This question was in another post and mentioned the removal and resettlement components of integration, which I've tried, but it did not help. I also checked that I have the latest version of the integration components (v. 14.1.7600.16403). I have a separate instance of Virtual PC that I brought over my old XP machine and it was never a problem with integration. The problem with the image in XP Mode occurs also, regardless of whether or not the other Virtual PC image runs. Only the image of the XP Mode has this problem. I suspect it's perhaps a conflict of TCP port in the named pipe, but if so, I don't know how to solve. Thanks in advance to anyone who might be able to offer advice.

    Thanks for the reply. I tried to reinstall the integration features in the past, but the problem has come back at a later date. A few days after I posted this request for assistance, I needed to log out of Windows 7, so I hibernated the XP Mode image. Then, I opened a session in Windows 7 and thought I'd give it a try once again, and it worked this time! I did nothing special. So hopefully that will happen in the future, just as it went and on the past few months. Enjoyed your attempt to offer advice, however!

  • IMAQ Grab Acquire.vi error when you use an external trigger on a card NI PCIe-1433 (sync problem?)

    According to my recent post on getting up and running with the NI PCIe-1433 camera link card, I ran into a bit of a snag.

    When you use the internal trigger on the camera, everything works 100%. I can view all the data from the camera in MAX as well as in the labview project. However, whenever I have set the mode switch is where things start to fall apart.

    What I have confirmed:

    -Camera is switching between inside and outside triggering.

    -NI PCIe-1433 camera link card is set up properly. While in external mode, I can trigger the camera by using a function generator and check the wire to the MAX. Everything works fine.

    When the unit is in external mode, the function Acquire.vi enter IMAQ - my mistake VI. The error is:

    Code :-1074397150

    The possible reasons for a timeout.

    Now, I have it set up so that a mistake here will not end the LabVIEW file. Sometimes, data of interest makes however (about every 10 seconds-ish). So what seems to be the case, it's that this external trigger signal is not in the lineup when the clamp is attempted. Is it possible to synchronize these? May reference the trigger signal external sort in my LabVIEW project so that the clamp is performed only when that trigger impulses?

    So I solved my problem. He was in time. The external trigger that I used for the device was simply too slow. I was initially using a trigger from 2 Hz to be able to view the values changing on LabVIEW probes. But it was enough to get enough data to move above the camera cable to assemble a picture and kept it in time. Travel up to 9 kHz solved the problem. No adjustment to the camera settings or LabVIEW code was necessary.

  • Cannot move all the files as windows explore crashes - it happens every time when you use an external hard drive (several readers have been tested and work on other machines)

    Make sure that the device is compatible with Vista, the Vista Compatibility Center: http://www.microsoft.com/windows/compatibility/windows-vista/default.aspx.

    If you need to get pilots to leave the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.  You need to find the NAS device and the NICs in particular - but it would not hurt to look at all the when you're there.

    Go to start / Control Panel / Add Hardware and select the first option (recommended) to see if the system can detect the device.  If this does not work, choose the second and provide the information requested on the device.  You will be asked for drivers - have their practice.  Follow the prompts to install the device (NAS).  Make sure that it is plugged in and turned on when you do so, or he not be recognized.  It's the hard way of installing a hardware device, but your system obviously isn't automatically recognize it then do it manually. Here is a brief tutorial on how to do so: http://www.web-articles.info/e/a/title/Windows-Vista :-Running-the-Add-Hardware-Wizard /.

    I hope this helps.  Good luck! Lorien - a - MCSE/MCSA/network + / A +.

    Hi the string 1,

    Make sure that a certain folder path is in the PATH environment variable. Follow these steps:

    (a) first, to determine the correct path to add to the PATH environment variable.  Look in C:\Windows\twain_32 and there should be another folder (example:-CNQ4803). This is the way that is needed to be added to the PATH environment variable. C:\Windows\twain_32\CNQ4803

    (b) alter the PATH environment variable. Go to Control Panel, Systemand then choose Advanced system settings in the left column.

    (c) this will bring up the System Properties dialog box (it should already be in the Advanced tab).

    (d) at the bottom of this dialog box is a button Environment Variables .  By clicking on this button to display the Environment Variables dialog box.

    (e) in the bottom panel, scroll down until you find the variable named Path.  Select it and then press the Edit button to bring up the Edit System Variable dialog box.

    (f) in the Variable value text box, scroll all the way to the right, and then add the C:\Windows\twain_32\CNQ4803 path that was determined earlier.  Be sure to separate this value by a preceding semicolon.  And also be ensure not to make further changes to this value. Click OK.
