Can somebody plz help me?

C:\, C:\WINNT are directories unrelated to Tomcat that Tomcat doesn't know about (unless you told it about them in the conf/server.xml file).
A simple solution without editing your server.xml file is to use Tomcat's ROOT directory.
This directory is by default <Tomcat install directory>\webapps\ROOT
(For me it's : C:\Program Files\Tomcat 4.1\webapps\ROOT).
In this ROOT directory you have the WEB-INF directory wich contains the web.xml file.
Under this WEB-INF directory create a directory called "classes" and put a copy of you servlet class file in it.
The complete path of your servlet class file then should be
<Tomcat install directory>\webapps\ROOT\WEB-INF\classes\Brat.class
Try this and report if it worked.

Using iPod shuffle 4th generation for first time and receiving the error : one of the USB devices attached to this computer has malfunctioned, and windows does not recognize it. For assistance in solving this problem, click this message.
Using win 7 and latest iTunes [10.6.3]. Have already gone through below links and did not find any solution.
http://support.apple.com/kb/HT2292
http://support.apple.com/kb/TS1369
http://support.apple.com/kb/HT1923
http://en.kioskea.net/forum/affich-17997-ipod-not-detectedI was hoping it would be something like a USB device conflict, but now the shuffle is the only thing connected...
This article was one of the ones you linked to above in your initial post
http://support.apple.com/kb/TS1369
Under Part 9. Verify that USB drivers are installed, did you try the steps in If only "Unknown Device" appears? That appears to be your situation.
Also, you said that the shuffle initially worked well enough to do a sync, then it had the same problem again. If you can get it to work again initially, before doing anything else, try the following. Select the shuffle in the iTunes sidebar, under DEVICES. Over to the right, go to the Summary tab. By default, the checkbox for Enable disk use should be unchecked. If so, check it and Apply the change. See if that makes any difference.
(If Enable disk use was already checked, try unchecking it and Apply the change. Basically, set it the "other way" and see if there is any improvement.)
NOTE: When disk use is enabled, you have to eject the iPod in iTunes before disconnecting it physically.
If the disk use change makes a difference, that may provide a clue about the actual cause. -

The time capsule though blinks amber and the Airport Utility shows blinking amber light and has a red circle with the number 1 in it.
There is an error.. probably trivial.. firmware update, default password..
Open the airport utility and find out what the error is.
Simply click the TC and see status in the summary page.. it will list all the errors and what you should do.. fix or ignore them. ie this TC has an error.. default password.. I chose to ignore.. when I "fix" the problem the LED goes green.
Here is additional TC.. it is blinking amber with faults.
Click the fault. eg default password.
You can ignore or edit .. if you click edit it will take you to the full setup where you can change the settings.
I ignored my errors and now it is green.. -
Trying to update to iOS 7.0.2 but not having any success,message keeps appearing telling me there's an error but doesn't tell me what the error is,any information on how to sort this problem would be appreciated
Can you check that your Wi-Fi connection is working correctly?
Do you get that error right away at the beginning of the download or much later?
Have a look whether there is plenty of free space (several gigabytes) on your iPad to receive the new iOS 7 upgrade. Remember that the upgrade is downloaded in a compressed form.
It's difficult for me to give precise advice without knowing what caused the error.
If all fails, try to do the upgrade via iTunes with your iPad connected to your computer. -

Alternatively, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

MY IPHONE 3GS START TO GET REALLY HOT, AND AFTER THAT ALMOST EXPLODE...ITS BROKEN NOW.... THE BATTERY GETS FAT... WHATS THE SOLUTION NOW???
Unfortunately it looks like your 3GS' battery has expanded so much that it cracked the whole case wide open. If you have AppleCare on your device then you're all set, just take it to your local Apple Store.
If not, then still take it to the store. Complain about the battery bursting, and make sure to tell them that it's for sure a defect (you'd think it's obvious, but sometimes you just need to drive the point in), and that it potentially could have been and still be a hazard.
Remind them that the phone has not been in any adverse conditions, extreme temperatures, or abused in any way but that you just merely used it normally. (I'm assuming that's the truth?)
If they're good about it they should replace the broken phone for you; but unfortunately there's little chance of repairing your current device. -
