This program should work????

I have a program that works at home.
My webserver at home is tomcat and here the program works.
At the remote location the web server is also tomcat. The program fails here but I have not changed on line of code???
My html and jsp pages are located at this location:
/cscs/www/tomcat/webapps/w0109699/grid-portal-project
my ".class" files are in a folder called "ftp" at this location:
/cscs/www/tomcat/webapps/w0109699/WEB-INF/classes
ftp
I can view all html pages but when I call a jsp page that tries the acces the bean it gives me the error.
Please help??????

Hi,
I've ran into the same problem: I just installed SDK1.4.1 and Tomcat 4.1.12 on a Linux server (on my W2K laptop this runs fine) and just about every JSP gives me this error:

foolishmatt,
The code is quit large.
to understand the program I think all the code needs to be examined.
I would need to send to you in an email.
Here is my e-mail
[email protected]
if you contact me than I can send the code to you.
Thank you in advance.

I need help getting this program to work.

K. I don't pay much attention in my AP Comp Science Class.. but my teacher said if i can get this program to work i get an a for the semester... The program is Metrowerks Codewarrior IDE.. we are running it on windows 98 i think. She said she can't get it to compile.. so i guess it just needs to be able to input simple java programs (i.e. loops, just the regular crap) and compile them and run them...i have no clue what is wrong with it.. it could just need a patch...or we may just be going about it the wrong way...any help would be SUPER appreciated...

How can I get this program to work -- Adobe Send or Adobe SendNow

How can I get this program to work? I have used Adobe SendNow successfully for several years and am on automatic renewal and getting nothing but frustration for my money! I have been unsuccessful at sending anything in the past several months. Today while working on a deadline and many unsuccessful attempts to upload files, I signed up for a free trial at a competitor in order to get my files sent. Want a refund -- or better yet, keep my money and get it to work right again.

You can't.
Sounds like it he gave you a stolen iPhone or at least a worthless one.

Program should work for any DB..and give me the space detials..!

Hi All,
I have a requirement like, whatever the SAP Report program im going to write that should work for any underlying DB.
Like I have bunch of tables like LFA1, MARA etcu2026
I wll check like if sy-dbs = u2018ORACLEu2019
Here I need some code (Table) / FM (ORA) should be there to give me the used space and free space of that particular table like LFA1.
Else I wll check like if sy-dbs = u2018DB2u2019
Some code/FM like above to give me used space and free space.
Else I wll check like if sy-dbs = u2018Sybaseu2019
Some code/FM like above to give me used space and free space.
I wll check like if sy-dbs = u2018Informixu2019
Some code/FM like above to give me used space and free space.
I wll check like if sy-dbs = u2018MaxDBu2019
Some code/FM like above to give me used space and free space.
I need Some DB Table / FM for each DB, which should give me the space details.
Please let me know.

Careful here Pradeep, this is not valid syntax.
status = case endtime
when null then "error"
when not null then "successfull"
endYou want:
SQL> select case
2            when endtime is null then 'error'
3            when endtime is not null then 'successful'
4         end
5 from t;
CASEWHENEN
error
(and you don't really need both conditions since they are mutually exclusive)

Does this program really work?

I got this link for a convert program from this forum but I don't want to buy it unless I know its going to work. I already got QT pro just to find out that it didn't convert my files right and now i'm stuck with it.
http://www.divmm.com/
The program is called Video Vault, it clames to convert DVDs, VCDs, SVCDs, Analog/Digital Camcorder Tapes. Files types = AVI, Mpeg1, Mpeg2, Mpeg4, ASF, WMV, DVR-MS, TIVO, VOB
Most of the video formats I have are AVIs and MPEG1s and nothing else seems to do it right so if anyone has used this program can you please tell me if it really works?
thank you

"Most of the video formats I have are AVIs and MPEG1s"
Videora will work just fine for you. It's free, and most users here use it.

Anyone know why this program aint working

i pretty much copied most of the code from an example program but this one doesnt seem to be working
the error says i need another } but keeps saying the same thing when i add one
import java.io.*;
//this is a cprogram i have created so the users data entered into my main program can be read in a text file
class cdetailreader
     public static void main (String args[])
          int input;
          try
               // I have created a filereader to read the contents of the text file i created to hold customer data
               // In my main program i named the text file to store customer details cdetails.txt
               FileReader readcdetails = new fileReader("cdetails.txt");
               input = reader.read();
               While (input >=0)
                    System.out.print ((char) input);

          catch(Exception e){
          System.out.println("File does not exist"+e);
}

nice one mate it is actually a error in the program
example but should have guessed. thanks for helpI suggest you ditch that source and find another one that doesn't suck.

Is there anyway this program can work the way I want it to work!!??

Since I had no idea, how to make a new line in .txt in my program(writeBytes("\n") will just make a rectangle in the .txt file)..i decided that I should make a method..below:
public static String makeLine(int bytesReq)
          String lines = " ";
          //bytesReq /= bytesReq;
          for(int i = 0; i < bytesReq; i++)
               lines += lines;
          return lines;
     }I wanted program to create a string of empty spaces..depending on the number so I can use it later...in this code..which transfers the stuff inside my link list into the .txt file...

     }when I compile it seem to work but when I run it...it has a OutOfMemoryException..and I don't know why..later I used the length of the string of the ID, Firstname, Lastname but then...something weird happens....
all of them is repeated three times in .txt and I have no clue why?..
And right now the .txt file has some kind of east asian characters written in it and is 513KB and still don't have a clue why...
all I want is to have the next set of data go into the next line....
Please help...

This returns a string 2^bytesReq long because it doubles in length on every pass.

Why this program doesnt work... what it supposed to do

          System.out.println("GFC" + " " + int3);
IT SHOULD BE LIKE THIS
sample is
first input is 100
sec input is 70
series 30 40 10
GFC should be 10
but out put is 30 40
GFC 40
it doesnt follow the while int3==0
please help

import java.io.*;

System.out.println(" " + int3);
while (x<0);
System.out.println("GFC" + " " + int3);
FIRST YOU HAVE TO ENTER 2 INPUTS
THE FIRST INPUT("INT1") IS SUBTRACTED FROM THE SECOND INPUT("INT2") THE OUTPUT WILL BE THE THIRD VARIABLE WHICH IS "INT3"
THE SYSTEM WILL THEN CHOOSE FROM INT2 OR INT 3 IF WHO'S GREATER OR LARGER
IF THE SYSTEM DETECTS THAT INT2 IS LARGER THAN INT3 THEN INT1=INT2 AND INT2=INT3
ELSE IF THE INT3 IS GREATER THEN INT3 WILL BE THEN INT1=INT3 AND INT2 WILL REMAIN THE SAME
UNTIL IT REACH THE CONDITION INT3==0
SAMPLE OUTPUT SHOULD BE
<INPUT 1ST>10
<INPUT 2ND>2
OUTPUT SHOULD BE IN
SERIES LIKE 8 6 2
GFC IS 2
BUT WHATS HAPPENING IS IT PRINTS 8 AND 6 .. AND THE GFC IS 6 ...
ERRR DID I EXPLAIN IT RIGHT?

Plese i must to understand how this program is working for my project

Do you have any specific question? Maybe you should ask whoever wrote it.
Pictures are pretty useless for code analysis. We prefer actual VIs. What are the names of the subVIs? Do they have any context help? What's in the hidden cases of the case structures? How are the digital IOs configured? What is the FPGA hardware?
Just knowing what each part is called is not sufficient to understand LabVIEW code. Maybe you should start with a few tutorials.
(Some of he code seems rather silly. Why is there a local variable "A" instead of branching the wire from the terminal? Why are there two instances of the "Low Triangle" local variables read in parallel and each divided by the same constant? Wouldn't once be enough, followed by branching the wire at the very end?)
LabVIEW Champion . Do more with less code and in less time .

This program doesn't display the results :-(

this program should output the sum,difference,product and quotient of two numbers.
i guess the computeQuotient is the wrong part..
import java.util.*;
public class MethodExample2
     static Scanner get = new Scanner(System.in);
     public static void main(String[] args)
          double sum,difference,product,quotient;
          double n1,n2;
          System.out.print("Enter the first number: ");
          n1 = get.nextInt();
          System.out.print("Enter the second number: ");
          n2 = get.nextInt();
          sum = computeSum(n1,n2);
          difference = computeDifference(n1,n2);
          product = computeProduct(n1,n2);
          quotient = computeQuotient(n1,n2);
          System.out.print("Sum: " + sum);
          System.out.print("\nDifference: " + difference);
          System.out.print("\nProduct: " + product);
          System.out.print("\nQuotient: " + quotient);
          System.out.println();
     public static double computeSum(double num1,double num2)
          return num1 + num2;
     public static double computeDifference(double num1,double num2)
          return num1 - num2;
     public static double computeProduct(double num1,double num2)
          double res = 0.0;
          for(double ctr = num1;ctr > 0; ctr--)
                    res = num2 + res;
          return res;
     public static double computeQuotient(double num1,double num2)//i guess this is the wrong part
          double res, ctr;
          for(ctr = 1; ctr >= 0; ctr++)
               res = num1 - num2;
               num1 = res;
          return ctr;

Dear Sir:
The ArithmeticException is RuntimeException, therefore it is unchecked exception.....
Here is my dumb program for your reference....
import java.util.*;
public class ScannerExp{
     static Scanner get = new Scanner(System.in);
     public static void main(String[] args){
     double sum,difference,product,quotient;
     double n1,n2;
     System.out.print("Enter the first number in double format: ");
     n1 = get.nextDouble();
     System.out.print("Enter the second number in double format: ");
     n2 = get.nextDouble();
     sum = computeSum(n1,n2);
difference = computeDifference(n1,n2);
     product = computeProduct(n1,n2);
     quotient = computeQuotient(n1,n2);
     System.out.print("Sum: " + sum);
     System.out.print("\nDifference: " + difference);
     System.out.print("\nProduct: " + product);
     System.out.print("\nQuotient: " + quotient);
     System.out.println();
     public static double computeSum(double num1,double num2)
          return (num1 + num2);
     public static double computeDifference(double num1,double num2)
          return (num1 - num2);
     public static double computeProduct(double num1,double num2){
          return (num1*num2);
     public static double computeQuotient(double num1,double num2){
return (num1 / num2);
use
jacvac ScannerExp.java
java ScannerExpthen input the number you want to compute....
Hope it is half right....

MP-101 paper jams my MG3100 printer. Manual says it should work but it doesn't. Can someone help?

Subject says it all. I got MP-101 paper for my MG3100 printer. The manual for the printer says this paper should work fine, But the printer fails to pull it all the way through and my printer jams. Is this a typo in the manual, or is there some way to get it to work? I set the printer to Photo paper on the actual printer itself, and choose "Matte Photo Paper" on media type inside the printer properties.

Apple keeps your last 3 backups by making a complete backup of your device at the time of the backup, then keeping any changed files in case you want to restore to an ealier backup. So it does, for the most part, overwrite the current backup. However if your backup significantly increased in size it would have to allocate more space in order to maintain the ability to go back to your earlier backups. An option to try if you don't care about maintaining the ability to go back, is to delete the existing backup. This would delete the entire backup history and may clear enough space to create a fresh backup. You wouldn't know unless you tried.

UEFI PXE wont boot. very basic setup it should work

Hi all.
I am having problems booting Uefi PXE .
The client is a VM running in ESXi
WDS/SCCM Server is VM running ESXi
DHCP is VM running ESXi.
All VMs are on the same Host and Same Vswitch.
Dhcp option 60 = PXEClient
Option 66 = *ip address of WDS/SCCM*
Option 67 = /SMSBoot/x64/wdsnbp.com
Whit the above option i can boot Legacy clients via PXE fine .but not UEFi.
I read some where i must change the Option 67 = /SMSBoot/x64/wdsmgfw.efi
Which still does not work for me.
This setup should work as the Client server and dhcp are on the same broadcast domain.
Yes i have advertisements for All unknown Systems, and the OU of the computer.
What am i missing ?
when i try to boot a VM with EFI i get error PXE-E21

Yes, those options are not recommended, use of IP helper is advisable:

Why do i need to declate methods two times for this program work

Hi,
why should i have to declare 2 times the methods
public void mouseClicked(MouseEvent e) {    }
public void mousePressed(MouseEvent e) {    }
public void mouseReleased(MouseEvent e) {    }
public void mouseEntered(MouseEvent e) { }
public void mouseExited(MouseEvent e) { }
to make this program work? why when i declate 1 time this program doesn't work good?

public void mouseExited(MouseEvent e) { }
} the problem is this line bu.addMouseListener(new MouseListener() {
if i change this to bu.addMouseListener(this() {
it gives error saying expected ')'
and then doesn't compile.
i just don't know why , although the program runs when i declare the methods two times,
but i think it's better java code , if i learn it why is this error and correct it

This program should work????
