URGENT HELP NEEDED!!! (Almost a matter of life and death)

Well, it's more of a matter of failing a course or not...
Anyway, my Java professor gave us some labs to do. I know Java front and back, at least, whatever version I learned a few years back. This is my first tenure with the Scanner object, and it's messing me up.
I'm using Eclipse for my project. I have three files in the source folder, ABC_Manufacturing.java, mseast.dat and mswest.dat. Now, when I try to instanciate a new Scanner object, it won't find the files:
Scanner east = new Scanner(new FileReader("mseast.dat"));
Scanner west = new Scanner(new File("mswest.dat"));
I'm trying two seperate ways to do this. Neither are working, this is the error I get:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
     Unhandled exception type FileNotFoundException
     Unhandled exception type FileNotFoundException
     at ABC_Manufacturing.main(ABC_Manufacturing.java:38)
Now, I added these files OVER and OVER again. I added them. I created new files and pasted the contents in there. I used .txt files. All the same error. It's like it just won't take the time out to look for the files that are RIGHT IN THE DAMN PROJECT! Then I tried using a complete path, using C:\Java\whatever. SAME ERROR!!!!
Please, I need urgent help. This is due tomorrow at noon, and I have no idea what to do at this point. I can't really continue, because at this point its just looking at what prints out and formatting it, and I don't want to do that without testing to see if my code to convert the file data into arrays work. You dig? Thanks for any and all help, and I'm going to kill my professor...she spent a week going over parallel arrays but did nothing to show us how to import files into projects or use the scanner class. Also it doesn't help that at uni we have to use emacs, which I don't use at home.

This is the the main class, so far:

          int [] eastQuant = new int[13];
          int [] westParts = new int[17];
          int [] westQuant = new int[17];
          System.out.print(west.nextInt());
And I didn't ignore that one guy (sorry, don't remember your username) I tried you and the other guy's responce. Both didn't work. I dunno how to get around errors. Figures, you don't learn that in the course but she'll spend a week on parallel arrays...Ok, well that can't possibly be complaining with the same error message you got before, so now you need to be (more) specific about what "didn't work" means.

URGENT HELP NEEDED ... Tomcat Realm and JRE1.4 plug-in problem

I have tried the Security Realm of Tomcat. Since I do not have
an LDAP server, I decided to use the Tomcat-users.xml file in
Tomcat\conf directory.
I added the following lines of code in the web.xml file.
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>

<role-name>webviewer</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Tomcat Manager Application</realm-name>
</login-config>
The <role-name> "webviewer" is added into "Tomcat-Users.xml" as the following:
<tomcat-users>
<user name="test" password="password" roles="webviewer" />
</tomcat-users>
So, now when we type the url: http://localhost:8080/adbpdbre/default.htm, TOMCAT shows a dialog box asking for UserName: and Password:Now, only when we give the username and password, it shows the page. This is exactly what we want.
But the problem now is, this default.htm page, has 5 links to 5 applets. The first time that I click on one of these links, the JRE plug of 1.4 shows a dialog again asking for the username and password. Till I dont provide the username and password the system doesnt go ahead and applet doesnt load. I do not want the JRE to ask me for the username/passwords again..How to avoid this ?
Can you give me some more information on this. Ultimately in the production usage, we will be using LDAP and not Tomcat's memory realm.
URGENT HELP NEEDED ... I need to get back to my client on this.
Help would be v. much appreciated.

In the config file, you 're essentially saying that you want Tomcat to prompt for usr/passw on every request (url-pattern = /*) made by a 'webviewer', and that's exactly what Tomcat is doing.
Consider using specific url-patterns & roles for resources to be protected. If for now, all you need is to protect the first page, use a more specific url-pattern.
Just an advice : if you'll be using LDAP in production, do not waste time with Tomcat's Security Realm and the BASIC authentication type, since the two have not much in common. Start reading doc on LDAP, and code a prototype, or even better, a vertical slice of the app (i.e a proof of concept).

(Urgent help needed) how to read txt file and store the data into 2D-array?

Hi, I have a GUI which allow to choose file from the file chooser, and when "Read file" button is pressed, I want to show the array data into the textarea.
The sample data is like this followed:
-0.0007     -0.0061     0.0006
-0.0002     0.0203     0.0066
0     0.2317     0.008
0.0017     0.5957     0.0008
0.0024     1.071     0.0029
0.0439     1.4873     -0.0003
I want my program to scan through and store these data into 2D array.
However for some reason, my source code issues errors, and I don't know what's wrong with it, seems to have a problem in StringTokenizer though. Can anybody help me?
Thanks in advance.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

URGENT HELP NEEDED - iPhone 3Gs no longer detected or charged by MacBook

My iPhone 3Gs (3.1) has been running fine, until several hours ago today, when I plugged it to my MacBook, the iPhone is no longer detected - it doesn't show up in iTunes, nor it is charged. I tried opening iPhoto, and it wasn't there too. Not with Image Capture too. I tried charging it using the out-of-box wall charger using the same out-of-box USB cable I use for MacBook, and it can be charged without any problem. Then I put it into Recovery mode, and there iTunes can see it. I don't want to restore it before I figure out exactly what went wrong, as I don't want the restore process somehow gets stuck in the middle that the connection is lost again.
I've tried reinstalled iTunes, including completely removal of Apple Mobile Device Support, as instructed by Apple. But still no luck.
I've tried switching to another USB port of my MacBook. No luck.
My iTunes is the latest 9.0.1, and my Mac OSX is 10.6.1. My iPhone is on 3.1, upgraded from 3.0.
I've read from web that it seems I'm not the only one out there having this problem. But none of them seem having any real working solution.
Urgent help needed & appreciated. Millions of thanks in advance.
Gary

1. I used both cables - theirs & mine ... and on several macs
2. yes, same cable for wall & mac
3. as said, i did completely remove & install itunes (incl. apple mobile device support), as instructed on the apple webpage
anyway, did a restore just now. it seems okay now. but the problem is i have no idea what cause this, and i can't replicate the problem. so i don't know when it will happen again ... maybe a bug with os 3.1 ... others on web said os 3.1 is quite buggy ...

Urgent help needed, can I restore N900 Backup file...

i owned a N900 (now sold out)
before selling i took backup of contacts from backup restore option in application section
now i bought a N8 but i m not able to restore my contacts
1. is there any way to restore them in N8?
2. if not, can i convert them in TEXT or any readable format
urgent help needed
thanks in advance

The backup procedures built into the phone are only designed for restoring to the same phone (ie: in case or data corruption, software update or repair etc.), they can't usually be used to restore to a phone with a different operating system.
You should have backed up with Ovi Suite before selling the N900, that would have been able to restore to the N8.

Urgent help needed with un-removable junk mail that froze Mail!!

Urgent help needed with un-removable junk mail that froze Mail?
I had 7 junk mails come in this morning, 5 went straight to junk and 2 more I junked.
When I clicked on the Junk folder to empty it, it froze Mail and I can't click on anything, I had to force quit Mail and re-open it. When it re-opens the Junk folder is selected and it is froze, I can't do anything.
I repaired permissions, it did nothing.
I re-booted my computer, on opening Mail the In folder was selected, when I selected Junk, again, it locks up Mail and I can't select them to delete them?
Anyone know how I can delete these Junk mails from my Junk folder without having to open Mail to do it as it would appear this will be the only solution to the problem.

Hi Nigel
If you hold the Shift key when opening the mail app, it will start up without any folders selected & no emails showing. Hopefully this will enable you to start Mail ok.
Then from the Mail menus - choose Mailbox-Erase Junk Mail . The problem mail should now be in the trash. If there's nothing you want to retain from the Trash, you should now choose Mailbox- Erase Deleted Messages....
If you need to double-check the Trash for anything you might want to retain, then view the Trash folder first, before using Erase Junk Mail & move anything you wish to keep to another folder.
The shift key starts Mail in a sort of Safe mode.

IPhone 3G 8GB Crashes when syncing with iTunes. URGENT HELP NEEDED.

I have latest iTunes and OS on my iPhone 3G...
Every time i plug my iPhone in it begins to sync and then iTunes will freeze and not respond..
I have tried re installing iTunes.. I can't reset my iPhone as i can't create a backup..
URGENT HELP NEEDED PLEASE!

I don't have an iphone, but if it's anything like my click-wheel ipod, a reset doesn't delete anything.
It just resets the ipod's operating system, kind of like a PC restart. Did you try this Sleep/Wake button thing mentioned here?
http://support.apple.com/kb/HT1737
Maybe it's a podcast of voice memo causing the problem like it did for this person
http://discussions.apple.com/message.jspa?messageID=10907809#10907809
That's all I got. You might have better luck on an iPhone forum. Everyone there would probably have one. Like I said, I don't.

Computer restarts when ipod is connected urgent help needed

alright this is weird, I've had my ipod for ages and suddenly I go to plug it in and the computer slows down really really really slow and eventually just turns it self off, restarts and then sits in a black screen. if I leave the ipod plugged into the computer and restart it again it just goes straight back to the black screen, but both my ipod and computer work fine when there not connected. i have the latest version of itunes which seemed to help the first time i tried it actually started to update the ipod but then guess what the computer has another heart attack. urgent help needed please!!!

if I leave the ipod plugged into the computer and restart it again it just goes straight back to the black screen
Given this, I'd put it down to a flaky power supply in the computer. Might want to try using another computer or replacing the PSU.

Plzzzz urgent help needed.
Thanks

rohini,
go to RSA1->Modeling->Source Systems and right-click on your BW system, and click on 'Replicate Datasources'.
also, go to the ODS that's causing the problem (via RSA1->InfoProvider and go to your ODS), right click and click on 'Generate Export Datasource'.
one more thing, make sure that all your record/s in the source ODS is active. if you're not sure manage its contents and click on 'Activate'. if there are any entries in the the next screen that comes up, you need to activate it first, then try everything again.
let me know what happens. also try to look for error messages in ST22 and SM21 that may be related to this and post whatever possible error you see there here.

Problem uninstalling MaxMSPRuntime on mac - urgent help needed

Hello there,
I've been using Cycle 74's MaxMSP Runtime version 5.1 for a while but recently had to witch to an earlier version to make some hardware function along side the Max runtime environment. The problem is that where i would usually just drag and drop Max 5.1 into the trash to uninstall it, for some reason, after i have done this and try to install the older version of Max, OSX wont let me install Max 4.0.8 as it says an updated version is currently installed. I have scoured my hard drive for the remanence of Max 5.1. and deleted everything i've found. Is there a way of overriding macosx and getting it to replace Max5.1 with an older version?
Urgent help needed as i am playing a show this weekend and currently am not able to get my equipment to function.
A shiny nickel for the one who saves my ***.
Thanks
Henry

Hi- Try this...
If you can, reinstall or use time machine to recover your recently deleted MaxMSP Runtime 5.1.
Then, download AppZapper. It is a utility that helps you cleanly delete programs off your mac. It is free for the first 5 uses.
http://appzapper.com/
Then, install AppZapper, and then go ahead and drag the MaxMSP Runtime 5.1 into it, and it should hopefully get rid of the pesky program

Recovering windows XP -Urgent help needed

I am new to Toshiba. I hav a 60 GB hard disk with no partition and windows XP home installed. I want to partition the hard disk now. Now after formatting the hard disk do i lose Windows XP HE completely or is there chance to recover it and reinstall it. Urgent help needed.

Hi
You can reinstall your notebook using Recovery CD. It is easiest and fastest way to reinstall OS, all necessary drivers and tools. Put Recovery CD into DVD-ROM, start notebook and press down C button. At the beginning there is choice between two kinds of installation (Standard mode and expert mode).
If you choose the first one whole HDD will be formatted and used for OS installation. With second one (expert mode) it is possible to install OS on first partition. It is also possible to define how big the partition should be.
Try it. It is very simple to do it.
Good luck
