Midlet working in wireless tool kit but not in real mobile

I have created a midlet having a login form which will ask for username and password. once enter the details and click on submit button it will invoke servlet in our server. servlet connects to ms-access database and checks for autthentication and send valid or invalid message to the midlet. if it is valid then menu will be displayed otherwise display message login incorrect. it is working properly in the j2me wireless toolkit(emulator). but when the application is deployed in the mobile it is always getting in valid message and displaying login incorrect form.
i am using apache as a webserver and it is connected to the tomcat using mod_jk to run servlets/jsps.
thanks and regards
phani.

    Hi
    Does the data that you send from your application reach the server?

  • Works in Main Application mode but not the orange NXT mode for some NXT's

    A simple Labview program designed using only NXT VI's worked  in the Main Application but not in NXT mode.  For some NXT's it  worked in both modes but for others, just in Main Application mode. I've tried  updating the firmware and plugging and unplugging the USB.  Any thoughts?

    I see. The problem is probably that when you are switching to the NXT Target mode, it is expecting to target the other brick to which you already deployed. If you right-click on the orange banner menu in the lower left corner, you should be able to select the other NXT, or use "Find NXT..." to scan/search for bricks.
    Also, I reccommend giving all your NXTs unique names so this is more obvious. (you can use the NXT Terminal tool to do that).
    If you still can't get the VI to run in target mode, restart labview.

  • How to use time capsule for wireless back-up but not internet?

    Hello,
    I have a tower and recently a laptop at work. The tower is connected to our local network with an ethernet cable and the laptop with wireless. So, the internet connection is fine for both.
    I was hoping to use my time capsule to do time machine backups on my laptop. Do you have any advice on how to configure this? I do not want to use the time capsule to extend my Internet, as I believe my work I.T. would prefer to handle all access to their  network.
    Perhaps there is some documentation about doing this that you could point me to? I have not been able to find it.
    Thank you for your help.

    Your original question was How to use Time Capsule for wireless back-up but not Internet?
    There is no reason for you to connect the tower....or anything else...using Ethernet if your goal remains that same as you stated.
    If you are asking if you can backup the Tower using Ethernet, and not wireless, then you can connect the tower to one of the LAN <-> ports on the Time Capsule....not the WAN port.
    Yes, it appears to work without plugging into my tower.
    Correct, it will work.
    I just have to select the network that it created. Of course, I have no access to the Internet while this is happening and it can not auto backup, unless I am on that wireless signal.
    As I stated, that is the downside to trying to back up without an Internet connection.  You have to establish another network...and backup over that network.
    If you are asking if you can stay connected to the work network while also backing up to your non-Internet "private" network, that is not possible.

  • IPod nano works with USB 1.1 but not USB 2.0

    Anyone using an iPod nano that works with USB 1.1 but not with USB 2.0? I am using Windows XP and when installing the iPod software from CD it recognizes the iPod and am able to transfer songs using iTunes but when installing SP1 or SP2 to enable USB 2.0 transfers, Windows XP only recognizes the iPod nano as a USB Mass Storage Device. This is the same with iPod Updater.

    I have a similar problem with the following configuration:
    - Dell Dimension 4100 Desktop with 2 integrated USB 1.1 ports, Windows 2000 SP 4
    - PCI 6-Ports USB 2.0 Card ("Mentor" resp. www.bona.com.tw), Model USB20-PCI/6P
    What works well?
    - All my USB add-ons (1.1 and 2.0) on the internal 1.1 ports as well as on the USB2.0 PCI card
    - iPod Nano 4GB on internal 1.1 ports (external drive in windows 2000 as well as iPod in iTunes)
    - iPod Nano works as well as on the USB 2.0 card ONLY WHEN my old 4-port USB1.1 hub is connected between Nano and USB card
    What doesn't works?
    My iPod Nano directly connected to the USB 2.0 card. Symptoms when connecting:
    - Windows is very slow, process "scvhost.exe" or "system.exe" using 99% of CPU for some minutes
    - iPod is recognised as external drive, but when I click on it, it is empty and copying files to it results in "I/O error"
    - iTunes doesn't recognise the iPod (of course, if even windows itself cannot read from it...)
    I removed all USB drivers, reinstalled iTunes, iPod (by the way, I still don't understand what "iPod update" is good for, except for updating the iPod's firmware), deactivate the internal USB1.1 ports, no result.
    Help!!!!!!!!!!!!!!!!

  • Safari (7.0.1) is non-responsive (spinning pinwheel) upon start up.  It will work in temp user account but not in my main user acct.  I tried reinstall via comman-r prompt on start up but the problem persists.  Any suggestion for reinstall or repair?

    Safari is non-responsive after intitial start up.  Before it can load the homepage (google), it will hang and give a perpetual pinwheel until I force quit the program.  Safari works in temporary user account but not in my primary user account.  I have reinstalled osx via the command-r upon start up and the problem still persists.  Any suggestions on how to reinstall or repair safari?

    Thanks for thinking about my problem. I've already experimented with creating a new user, a co-administrator. The programs don't crash when that account is running, just as they don't crash when the guest-user's account runs. So it seems that the problem is limited to the default user's account, which is the one that was running when I installed the updates to the OS and the firmware. Another clue is that the programs that crash as soon as they are launched are *probably* the ones that were open at that time in that account. Yet deleting Saved Application States does not keep the programs from crashing when next launched.
    So the mystery continues, but these additional facts will help with the diagnosis, I hope.
    Thanks again for your suggestion.

    Hope you can help.
    I have added a new email address but kept my Id, but I get busy when trying from iPhone to iPad as they are clashing. Like find my iPhone app hence trying to keep them all on one account

    IOS: using facetime http://support.apple.com/kb/ht4319
    using an ipad will use the email address since you can't make a phone call.  see the link.
    Your basically calling/emailing yourself that's why your getting a busy signal.

  • On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion. They DO work on a lenovo machine but not my imac

    On 2011 iMac, External Altec Lansing speakers no longer work after upgrading to Mountain Lion.
    They DO work on a lenovo machine but not my iMac. reset Pram - no luck. took speakers from wife's desktop, they
    do not work when jack plugged into my iMac - Sys Prefs "SOUND" only lists "internal speakers/ built in" as available options.
    I used my altec lansing speakers on 3 macs including this one for 5-6 years.....now with Mountian Lion I can only get internal speakers???
    Ideas? Any/All help would be greatly appreciated - been going nuts with this for 2 days now.

    Hi,
    When you start Messages fro the first time you are asked for an Apple ID
    When this is verified and entered it appears in Messages Menu > Preference > Accounts and is Enabled.
    The App should have also picked on on those iChat Accounst you had before.
    These should be Enabled if they were when you last used iChat.
    Exactly which "Accounts" are logged in can be seen in Message Menu > Accounts and will include the iMessage "Account" and Bonjour.
    In the Window menu you will see CMD +0 for the Messages window and CMD+1 for the "Buddies" window which is a combined list at this stage.
    Go to the Preferences > General Section and Untick the "Collect all accounts into one list".
    This will give you separate iChat type Buddy lists.
    You can check if that account/Buddy list is set to Invisible or if in the Preferences > Accounts > Security you have settings that will block some people from seeing you as On line.
    You are saying Buddies can see you as On Line which implies they are still sending to your AIM based Names (@Mac.com is a valid AIM Screen Name)
    I am not sure from your post if you are trying to iMessage their email IDs thinking they are Apple IDs and that they are using Messages as well.
    There is no Buddy list for iMessages side
    No-one can tell you are "On Line" until they have your details in the "To" spot in Messages with the correct iMessaged contact info (iPhone Number or Apple ID)
    Obviously an Apple ID can be an email or look like one.
    In some cases they are also valid AIM Screen Names as well.
    In the case or the @mac.com name you may have linked this Apple ID to iMessages as well.
