Generated JNLP sometimes does not parse the parameter

I use a .jsp file that has a content type of jnlp to start a program using WebStart. That's when I can analyze? UserID = theID from the URL and pass this (theID) as a parameter to the program webstarted. Usually it works, but sometimes I get the parameter as "null" instead. However, the parameter is specified in the URL used, and the problem will be solved often clicking again on the same URL. Does anyone have ideas what could cause this intermittent problem or how to check for it before trying to launch with WebStart? Currently, I solved by checking if it is null in the newly launched program and gives an error and released if, with a message to try again, but it is not ideal.

The line that creates the argument in the jnlp is:
< argument > - ssUserID = < % = request.getParameter ("userid") % > < / argument >

And the URL is of the form:
http://websitelocation.com/studyTests/tabtest.jsp?userid=X10 & School = HS2 & Class = P1

Thank you!

  • Satellite L655 sometimes does not recognize the wireless card

    I have a L655. Most of the time it works perfectly fine. Sometimes when I turn on my computer, it does not recognize my wireless card. He considers that it is not at all.

    The icon in the status bar says that there is no cable ethernet plugged in and nothing on the wireless.
    Usually this icon is not present, and one for the wireless is (whether it is connected or not and if there are connections available or not). In the device manager there is nothing for the wireless card.

    Under network card it has only ethernet. Its as if it does not exist.
    Basically the way to solve this problem is by restarting simply my computer until he figures it.
    Sometimes, it can take 5 or more times.

    Any help please?

    Hello

    What satellite L655-xxx you have exactly?
    As far as I know there are different models with different wireless network cards.

    Your BIOS is up to date? Please check this box.

    So now to a few proposals of solution:
    First of all that I recommend to check if the update of the Wlan driver would improve the Wlan functionality.
    In addition, you must deactivate the energy saving feature for Wlan in Device Manager and Windows 7 power options as well.

  • Inside af AF:selectOneChoice: table sometimes does not display the appropriate values, based on the results of the query of the view object

    Hello

    I use jdev 12.1.2.

    I have a few components of af: selectOneChoice that is contained in an af:table element.  The table is extracting lines from database and display data.  Now here's the weird part: sometimes the component of selectOneChoice will have the correct value selected, and other times it will be just left unchecked.  I can verify that the data in the object view lines are indeed correct after I request them.  The LOV for soc components are properly set up (some are configured as static list display objects and some are set up as model driven lists based on display objects).  I have just completely puzzled me as to why they work sometimes and then not work at times even though I am following the exact same steps to reach that point in my application.  Someone at - he never meets this problem before?

    Thanks for reading.

    Problem solved!

    For anyone having this problem in the future: do not try to do a partial trigger on a table that is not in the visible panelTab.  The problem is that when my view criteria applying, I was refreshing the TWO tables.  This caused that was not visible to lose the selectOneChoice selection, while the other table was very good.  Remove the partial relaxation for the table that was not visible caused the data to be maintained properly during the exchange between the tabs and change the view criteria.  Thanks for the help again Ashish, stumbled on the real root of the problem, after following some of your suggestions.

  • Scroller sometimes does not

    I have a vertical scroller in my application that sometimes does not recognize the scroll events. The problem seems to occur at random. For example, when you perform a "drag up" gesture to scroll down, about 70% of the time it works as you would expect and 30% of the time that nothing happens. Sometimes, I have to pass several times so he can finally scroll. It's very frustrating.

    The scroll in question contains 6 sprites. Each sprite is around 400 PX in height and has a labels 4 or 5 and a chart, which is a simple custom sprite object, I created using DrawPath. Content is not too heavy, it runs pretty smooth when it works.

    Everyone has similar problems with the class of a scroller QNX?

    Nevermind, I figured it.

    There was a sprite on top of the wheel that had the visibility set to false (a popup), and despite the visibility set to false, it seems that it was sometimes interfere with key events. I moved the popup off the screen and everything works great now

    I think it's one of those things. 1 you are not connected to anything with blue tooth here for you aren't really "use it" 2. Its a software problem and maybe if you take it to the apple store that they would turn you off and back on to reset it or you say to wait for the next update, if you want to save gas or if you ride or walk save energy if you the person who has a power car electric you can write a quick review with the Apple and say hey guys do a new update , I really need a heres my problem.

  • Dell Vostro 430 sometimes breaks down and does not find the hard drive in the bios

    So I have this old - ish Dell Vostro 430, intel cpu, windows 7 hard disk sata 250 GB, 4 GB of ram.

    Update BIOS to the latest version 2.4.0

    In certain exceptional circumstances, this PC sometimes crashes in windows, it is restarted, and then when he comes back it does not find the hard drive as a gift. He is not seen in the bios and does not start.

    To fix, I have to unplug the power cable, wait a few seconds, plug in, reboot the computer and it starts normally, load windows and everything.

    So far, I have tried to paginate on another hard disk, reinstall the Windows operating system from scratch, and same thing happens from time to time.

    It is difficult to find the cause of the problem, because this happens very rarely.

    Sometimes, when the pc is turned on for the first time in the morning, the hard drive is not found by the bios and we reappear at the same trick (disconnect the power cable) to take him back.

    When it crashes when using inside Windows, it seems that the reason is the computer can't find the hard drive.

    Such computer is out of warranty.

    It would be nice to just throw this computer because it is still fine for the work it has to do, + I have Windows and Office OEM license on it, as well as many other software that I have to reinstall etc.etc.

    No idea what I could troubleshoot?

    Maybe change the motherboard? How can I buy a new motherboard for an out of warranty Dell?

    While possibly keeping all the OEM licenses (Windows 7 and Office 2007).

    • Have you tried to replace the battery in the motherboard, if nothing else than to exclude it? CR2032, 3-volt lithium-ion, ~ $2 at discount stores. Do not forget to open the BIOS Setup and copy down all current settings first because remove battery BIOS resets the default values, which is maybe not correct for your specific system.

    • If you use a power strip or surge protector, have you deleted and the PC connected directly to a wall jack?

    If it is a motherboard defective and you replace it with another jury of Vostro 430, you shouldn't have any problems with Windows or Office licenses. Assuming you are using Windows Dell reinstall for exact same version of Windows drive that was installed at the factory, it should not even ask the product key, if you must reinstall Windows on the HARD drive. But even if she asks, there should be a sticker somewhere on the PC with your unique product key so you can enter if the installer made the request.

    and make sure you have the Office product key too...

  • When you visit some Web sites, Firefox does not display the topic sites and sometimes the text correctly. It seems broken and unreadable.

    I reinstalled a new version of Firefox and set all of the default settings, but the problem still persists. Running Windows 7 and I have tried several different browsers (IE, Safari, Chrome and Opera) and all seem to work well. Only problem is with Firefox. The only time it works great is when I do not allow the site to use their own fonts. For any help or suggestion would be greatly appreciated.

    These sites use the Helvetica font?

    There has been problems reported with older versions of the Helvetica font bitmap or Geneva or fonts (bitmap) that Firefox cannot display in this size.

    Firefox cannot display some old bitmap fonts in a larger size gibberish and display instead.

    You can test in zoom out (view > Zoom > Zoom out, Ctrl-) to make the text smaller.

    Uninstall (remove) all variants of this not working do Firefox, use another font or see if you can find a version of real type that does not show the problem.

    There was also the fonts with a reported Chinese name who self-identify as Helvetica, in order to check that as well.

  • In FF 25 on XP there was a star to the left of the navigation bar to open the bookmarks bar, now he is on the right, but does not open the box - what's up?

    I want this little star back that opens the bookmarks bar. It's just to the left of the field address on XP in FP 25. But Windows 8 in FP 25.0.1 is not there. Instead, there is a star that sometimes appears on the right side of the address bar. But the star on the right does not open the bookmarks bar. It shows only a list of bookmarks and options, which do not include the opening of the sidebar.
    This option has been removed and replaced by Ctrl B?

  • (sometimes does not) Edge browser

    Hi all

    Another question I have.

    The Microsoft Edge browser is really slow and sometimes does not. It is not load websites like on the DS of 640XL I had before. Try www.spiegel.de or m.spiegel.de.

    This does not delete the temporary internet files or switching between mobile versions and of office.

    I use my x 3 with two Sims (Telekom/Vodafone) and most of the time that it is connected to my wifi. I tried to disable wifi or mobile to check connection if that helps. But without success.

    Are there settings I could change so that the browser works as expected?
