Why JApplet and JSP cannot connect to MySQL
When i use applet connect to MySQL, it show that no suitable driver.
My program is
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.sql.*;
public class fuck extends JApplet implements ActionListener
private JButton bb = new JButton("update");
private JTextArea aa = new JTextArea(1,7);
private JTextArea ss = new JTextArea(1,7);
private JPanel pp = new JPanel();
public fuck()
Container c=getContentPane();
pp.add(aa);
pp.add(ss);
pp.add(bb);
c.add(pp);
bb.addActionListener(this);
public void actionPerformed(ActionEvent ee)
try
Class.forName("org.gjt.mm.mysql.Driver");
catch(ClassNotFoundException e)
System.out.println(e.getMessage());
try
Connection con =
DriverManager.getConnection("jdbc:mysql://localhost/air","root","");
Statement st = con.createStatement();
//PreparedStatement pst = con.prepareStatement(
// "update aa set condition=? where temp=?");
//pst.setInt(1,3);
//pst.setString(2,"hg");
//pst.executeUpdate();
ResultSet rs=
st.executeQuery("select * from aa");
while (rs.next())
aa.setText(rs.getString("temp"));
ss.setText(rs.getString("condition"));
st.close();
con.close();
catch(SQLException ex)
System.err.println("SQLException:"+ex.getMessage());
If I using JSP, it also have some condition
Clearly it is in the classpath, otherwise the error would have been "Class not found". But here's a quote from the documentation for the driver, the part that explains how to make a connection:// The newInstance() call is a work around for some
// broken Java implementations
Class.forName("org.gjt.mm.mysql.Driver").newInstance();The "broken Java implementations" it refers to are certain JVMs that run applets in browsers...

Why do I get "Cannot connect to ITunes Store" message on my IPad and IPhone?
Why do I get "Cannot connect to ITunes Store" message on my IPad and IPhone?
I have tried numerous times to connect to ITunes Store to update my current apps and continue to get this message. Apple has determined that it is not a device problem or an Apple problem. It has to do with ITunes. Can anyone help?I am having no problems downloading from the app store today. I just tried it again. However, I read some of those other discussions as well and there have been times when the iTunes or App Store has been out of commission. Don't hold your breath waiting for Apple to acknowledge it because that is not going to happen. That is not how they operate.
You can report it to them here ....

iam using iphone 4S with win 7 PC and i cannot connect to the internet through my phone but i tried with my other 4S and it works but what should i do for the first iphone 4S???
as i said i have two iphone 4S,,,,,
1st one --- has os 5.1
2nd one has os 6.0
i tried 2nd one with carrier reliance gsm nd it works with that personal hotspot setting using USB...
but i want to connect the first 4S with carrier TATA DOCOMO GSM but its not working with the same USB feature????
plz reply asap...!!!
thnxxx in advance!!!If not this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem.
Also heating sometimes works. See:
Why can't I select my wifi settings?
A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

Then:
Does the iOS device connect to other networks? See other networks? If yes that tends to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

}the problem occars when there are a lot of queries that the project is sending to the DB (about 10000) the last half queries fails and send an excaption .
after 2 minutes the system seems like working fine.
I am stack with this problem about a year and cann't resolve it.
any idea????
regards
amnon mwell...new it seems to work fine, but is it ok to
keep connection open for good ???
isn't there any other alternative ???I am bit confused are you pooling the connections?
If so, actually the connections will not always stay open.. they will time out after a while when they are not in use but to specifically answer your question.. how could it possible be a bad thing. If the server/your app was getting bogged down with opening and closing connections then pooling solves this..
Finally as to your question of the alternatives... if the problem was opening and closing connections and reusing them through a pool solved this then I think the answer is no. If you don't like a specific part of the way the pool works it is probably configurable in some way and you could always implement your own pool.. although I wouldn't overly recommend that. The bottom line is that you need to keep your connections open for reuse.. pooling is the simplest way to achieve this.. but no there is no alternative to keeping your connections open if you are having the load problems you described. -

We have just installed Lion and now cannot connect to MyExpat
we have just installed OS X Lion, v10.7.2 and now cannot connect to MyExpatNetwork on my Macbook pro. Any suggestions?
yeah-find out where you're downloading stuff to, and stick with it. I'm using FireFox and tell it to save the driver and stuff on the desktop, and when I quit FireFox, there it is on the desktop. you'll also need your admin password. It should show up as a .dmg file, then double-click on it to open it. You should see "Brother.pkg" . start up brother.pkg (double click??) and folow the instructions that ought to appear to install the printer driver. If the .dmg file doesn't mount, use Disk Utility** to mount it and get it working. Then you should see the package. and then you can install it.
** you may have to click on the .dmg file and choose "Get Info" then Open with, then choose disk utility, and then open with then change all. then close it. Hopefully that ought to work. If you cannot remember your admin password, I can't help you right now. Looks like you'd need it, to let Brother install that printer driver.
well, enough for tonight
if this didn't help you, then ask me again tomorrow

My mac air OSX10.8.5 won't connect to the internet. It says it has a 'self assigned IP address and therefore cannot connect to the internet'. Network diagnostics is unable to the solve the problem. It happened suddenly for no reason and now I cannot connect except by typing in the configuration settings manually. Please help me!
Use the Airport Utility or log into your wireless device via http and ensure the DHCP/NAT service is enabled. If accessing via HTTP, you will need to manually set an ip within your local subnet (eg: 192.168.0.x).

what shall i do if i forgot my ipod 5th gen password and i cannot connect it to a computer???????
ALSO THIS IS THE FIRST TIME SWITCHING ON MY IPOD IN 5 MONTHSIf no computer:
Only if:
If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.
Otherwise you need a computer with iTunes and an internet connection
Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode. -
i try to charge my ipod 4th generation but can not see the battary been charge and also cannot connect to itunes on my computer
Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order. -

Be patient, Apple is coming out with a update soon, its been reported that they have sent the update to the carriers to test, which means it will be soon. And is suppose to address this issue.

I get a message that my ipad 2 and iphone 5 cannot connect to the itunes store when I try to sync a book to my book app. Although, when I click "store" both are able to access the itunes store. Why is this? Also I tried to open a book that was synced and a message that I did not have enough memory to load this book popped up--when I know that I have well over 40gb of memory left in my ipad and over 16gb left in my iphone. The message that I cannot connect to the itunes store is strange that it offers no option and I have to hit OK to get out and use my ipad or iphone.
Try logging out of your account on the iPad by tapping on your id in Settings > Store and then log back in and see if it then works.
If that doesn't solve it then what has worked for some people is going into Settings > General > Date & Time and changing the date to a few months (or maybe a year or two) in the future and then re-trying
