MySQL db connection is working but can't launch my appliction

Hi,
I am working on a project using JDeveloper 11.2.3.0. I've configured database connection to MySQL DB and I can insert/update data using AppModule Test interface. However, when I try to launch the .jspx page on the Integrated weblogic server, I get below error

Please can you direct in which directory I need to place my jdbc connector jar file?

If it's showing the red disabled screen due to incorrect passcodes then you may need to put the iPad into recovery mode : http://support.apple.com/kb/ht1808 - you should then be able to reset the iPad via your computer's iTunes and restore/resync your content to it

Ask the Verizon store to exchange your iPhone for a different iPhone 4.
UPDATE - Sure, try ckuan's solution first. Then use mine if that fails.

I have an iPad3, recently updated the ios to 6.0.1. Since the update I cannot connect to wi-fi at my house. I am able to connect at work, but not at home. I have changed routers 3 times, have reset, uninstalled and re-installed, and everything I can think

I have an iPad2 and recently updated the ios. Since the update, I cannot connect to wi-fi through my router. I can still connect at work, but at home it will just not work. I have tried everything I can think of. I have reset, uninstalled, re-installed, and changed routers. 3 times. I cannot get it to work. Does this have something to do with the update? I have even reset the network settings, and restored the ipad itself to factory default settings. Can anyone help me?

Try and "Forget This Network"
Settings>Wi-Fi>tap little arrow on right of network.

Can connect to router but can't access internet on some devices

Hello everyone,
I'm fairly good with comptuers / networking but this issue has me baffled. Help would be greatly appreciated.
I have a linksys router (WRK54G) and have 2 desktops and 2 laptops connected to it wirelessly at the moment. I bought 3 smart phones (AT&T Tilts) and a new laptop recently. I don't use encryption but I do have MAC address filtering enabled.
The issue is that 1 of the smart phones can connect to the network and the internet, but the other 2 phones and the laptop can connect to the network but not the internet.
I did add their MAC addresses to the "allow" list ofcourse, which is why they're able to connect to the internet. DHCP is enabled, and these devices get an IP address. I can see them as connected when i log in to my router as well through one of my other computers (I see the MAC address and the IP assigned to those devices) so I know they're properly connected to the network. However, when i try to pull up a website (using either its ip or its domain name), the devices try to open up the page but eventually give me a "The page cannot be displayed or downloaded because the connection was lost" on the pocket PCs, and a generic "page cannot be found" on the laptop. I don't see these requests in the outgoing log table of the router either... I'm supposed to see them as when i use one of my desktops, I can see which site was accessed by which IP.
So basically, the requests from 2 smart phones and 1 laptop aren't even getting to the router apparently. What could be wrong? These devices can access the internet on other routers elsewhere at my workplace or at wi-fi spots.. just not at home, which is a major inconvenience. Why would the router be stopping some devices from connecting to the internet and allowing others? I know it's not a setting in the devices as it can access the internet through other wi-fi spots elsewhere..
Help will be truly appreciated.

Hi, I'm just getting up to speed on wireless but here's some info. Don't have a clue for your phones tho.
If you can connect to your network and talk to each other but can't connect to the internet, then it's an "Authorization" problem. I'ts not a Router "hardware" problem because your other equipment can connect to the internet (modem). It's not a Wireless card "hardware" problem on your laptop because you can connect to your network (router).
You say the Router sees the laptop/phones IP#'s but, do you see the IP#'s ON the computer/phones that can't get online? The Router sees them but do they see the Router?
The computers can talk to each other because your using the "Switched hub"(and wireless) part of the Router. I't doesnt do any translating, it just tells computer 1 that computer 2 want's to talk to it.
Is the Shared Key enabled on one and not the others?(Router menu)
If you can connect at work but not at home then again it's an Authorization problem. You have the right password, setup, etc, for work but not at home. "Hotspots" have no encryption so any one can connect. Do you have the home Router set up as WEP and and Work as WPA? Does your other laptop connect at work also? Do you have a mixed B,G,N band system at home. The Router has to be set at the band your using or have it set for mixed. If it's set for "G" only then any items that have B"or"N" won't be able to talk to it. If i go to a wireless motel thats next to a truck stop and a wireless Cafe, i can "SEE" a good half dozen "networks". I can even connect to a few of them, but, i can't get online because i don't have the password, etc..
Well one more kinda, sorta, possibility, did you lower the "Maximum number of DHCP Users" count to 4 (Router menu) and forget to raise it to 8 or what ever you have now? If you only had 3 computers on, then the Router would only hand out one more IP# so the other phones and laptop wouldn't get any more. It's defaulted to like, 20+ or so, so probably unlikely.
The First phone seems to be the magic bullet. My only suggestion would be to double check the settings and compare everything. You have got to be close.
I hope this get's you nearer,,

I am connected to wifi, but can't open webpages or collect mail

I am connected to wifi, but can't open webpages or collect mail. I have tried to reconnect; to forget the network, all those things that should hepl. My phone and my computer recognize the network, the ipad doesn't. I mean I am connected and have a full scala of connection bows, but nothing happens.

You iPad recognizes the wifi signal, but is not connected.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

I have digital copies of movies on my itunes at home and used cloud to download on itunes at work but can t find them

Are they gone completely from the computer, or just no longer in the library? Check your movie media folder.
If your'e in the USA you can download some movies a second time, but not all (studio dependent). You should always back up all media.

Just bought a new macbook air. speakers show that they work but can't hear Skype or youtube. Can you help?

Hi , just bought a new macbook air. speakers show that they work but can't hear Skype or youtube. Can you help?

Have you checked that they are selected in System Preferences>Sound>Output tab?
If that doesn't help, and although I've never had to use it myself, I've read on here occasionally that launching Audio MIDI Setup in the Utilities folder and messing with the settings in there can sometimes sort out audio problems.

HT1386 Syncing works but can't hear audio with headphones.

Syncing works but can't hear audio with headphones. Works without headphones though.

Have you tried other headphones?
What does syncing have to do with the problem?
- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.

While using Illustrator or Photoshop I seem to be hitting a shortcut to lock my key board. Other shortcuts work but can not type anything?

You are planning to do a number of things, so let me first make a suggestion about the overall approach. Instead of: "Before I make a clone of my hard drive I would like to fix this problem so I only have one account with everything in it but I do not know what to move ... or how to safely move it", I would make that clone immediately. And leave it alone until you have completed the reconfiguring and rearrangements you plan to do. This way, if you accidentally do something that needs to be undone, your clone is there with all the originals. By the way, this is the approach I always adopt, whenever I have to do anything drastic with an existing installation.
After all the rearranging etc. of the main drive you just make a new clone that erases the previous one.
The "Deano" account doesn't show up when I go to System Preferences:Accounts. So I assume I must have done something wrong.
This would suggest to me there is only one account, i.e. the principal, or Admin account. Why do you think there is a second account?
Where should I keep all my work files?
You can keep them where ever it is most convenient. As you know, you can create folders within folders, and there is nothing special about the Documents folder. Feel free to ignore it, if that's the way you want to work. You can direct your downloads, the default "save to" locations etc. to the appropriate places, as you work.
Can I create a new place for all my work files and just move them? I know I will have to update linked files within the various software packages but this is not a problem.
By all means.
.. can it be directly on the HD like my Applications folder etc.?
Indeed, yes. Or even on a different hard drive (or partition of the same drive).
And best wishes for the new year, to you too.

I just bought and downloaded Elements 12 but can't launch the program. Any ideas??

I just bought and downloaded Elements 12 but can't launch the program. Every time I try to sign in to my Adobe account to get started it shuts the whole program down everytime I click sign in. Very frustrated!! I had been using the trial version and loved it and want to work with the full version now!!!

If the trial version was still on the machine then you didn't need to install another program because Trial version can be activated by inserting your serial number and activated in the normal way.
I suggest try going to Help >> Activate
and see if you can activate it otherwise, if you can't launch the program then you need to uninstall the PSE completely from the Windows Control Panel and then restart the machine to make sure there isn't anything in the computer's memory.
Now restart the machine and install your program but this time making sure you also insert the serial number and your AdobeID so that you can register and activate the program automatically.
Good luck
