Still stuck with report problem
Hi guys,
As you said i downloaded crystal report and ireport.I tried to connect my database to ireport.i got it.i can view my report .but now i dont know how to call the jxrml file from jsp.i googled alot but couldnot find anything suitable for a jsp beginner.Please help me to solve this.I am in a dead end.
In your example you selected the pair with the greatest
distance from the first set, and the pair with the least
distance from the second. I don't see how the distance
function was used.
Also it's not clear to me that there is always a solution,
and, if there is, whether consistently choosing the
furthest or the closest pairs will always work.
The most obvious approach is to systematically try
all possibilities until the answer is reached, or there
are no possibilities left. This means backtracking whenever
a point is reached where you cannot continue. In this case
backtrack one step and try another possibility at this
step. After all possible choices of the previous step,
backtrack one more step and so on.
This seems rather involved, and it probably is.
Interestingly, if you know Prolog, it is ridiculously
easy because Prolog does all the backtracking for you.
In Java, you can implement the algorithm in much the same
way as Prolog implementations do it--keep a list of all the
choice points and work through them until success or there
are none left.
If you do know Prolog, you could generate lots of random
problems and see if there is always a solution.

Still stuck with the same old producer consumer weight problem need help
Hello All,
This is the problem I am stuck with right now.
I have two array lists one producer array list and one consumer array list denoted by a and b
P1 P2 P3 P4 P5
5 6 7 8 9
C1 C2 C3 C4 C5
2 3 4 5 6
Now we find all those producer consumer pairs which satisfy the criteria Pi>=Ci
We have the following sets
(5,2)(6,2)(7,2),(8,2),(9,2)
(5,3)(6,3)(7,3),(8,3),(9,3)
(5,4)(6,4)(7,4),(8,4),(9,4)
(5,5)(6,5)(7,5),(8,5),(9,5)
(6,6)(7,6)(8,6),(9,6)
Let us done each of them with Si
so we have S1,S2,S3,S4,S5
we assign a third parameter called weight to each element in Si which has satisfied the condition Pi>=Ci;
so we we will have
(5,2,ai),(6,2,bi),(7,2,ci)....etc for S1
similarly for S2 and so on.
We need to find in each set Si the the pair which has the smallest weight.
if we have (5,2,3) and (6,2,4) then 5,2,3 should be chosen.We should make sure that there is only one pair in every set which is finally chosen on the basis of weight.
Suppose we get a pair (5,2,3) in S1 and (5,2,3) in S2 we should see that (5,2,3) is not used to compare to compare with any other elements in the same set S2,
Finally we should arrive at the best element pair in each set.They should be non repeating in other sets.
Given a problem
P0 P1 P2 P3 P4
9 5 2 2 8
6 5 4 5 3
C0 C1 C2 C3 C4
we have So as (P0,C0) and (P4,C0)
assuming that the one with the smaller index has lesser weight PO is selected.In the program I have used random weights.from set S1 we select the pair PO,CO
S1 =(P0,C1),(P1,C1) and (P4,C1)
since P0 and P4 are already used in previous set we dont use them for checking in S1 so we have (P1,C1) as best.
S2=(P0,C2),(P1,C2) and (P4,C2) so we dont use P0,C2 and P1 and C2 because PO and P1 are already used in S1.
So we choose P4,C2
in S3 and S4 ae have (P0,C3),(P1,C3),(P4,C3) so we dont choose anything
and same in S4 also.
So answer is
(P0,C0),(P1,C1) and (P4,C2).
My program is trying to assign weights and I am trying to print the weights along with the sets.It doesnt work fine.I need help to write this program to do this.
Thanks.
Regards.

Stuck with grub problem (SOLVED)
Today i tried to upgrade my Arch Linux, it downloaded everything that should be downloaded, it was installing upgrades but at the installing grub it stucks as like this
"Copying /boot/grub/grub.cfg.pacsave to /boot/grub/grub.cfg"
I've waited it for about 15 minutes, it didn't move on. So i did ctrl+z to break. Then i tried to update again. But it gives an error which is:

In and not in - stuck with exclusion problem
From the following data
ID REF_NUM FLAG
L000304T 117930 M
L001538N 126199 R
L001538N 126191 M
L006339H 150427 N
L008519X 139085 R
L008519X 139075 M
L008579J 402452 R
L008579J 144668 M
L008579J 402429 R
L043884W 447519 R
L043885H 303383 C
L043886X 303383 R
The valid records are those with R
We want to delete only those records with the IDs are in valid record but REF_NUM is not corresponding to that valid id.
e.g in the above case
L001538N 126199 R --- is valid hence
L001538N 126191 M -- is invalid, to be deleted
similarly the other invalid records to be deleted are
L008519X 139075 M
L008579J 144668 M
We tried the query below, it is doesnt work.
select *
from FLAG_LKP del
Where del.REF_NUM not in
(select sel.REF_NUM -- selects all records with FLAG as R
from FLAG_LKP sel
where sel. FLAG = 'R'
and sel.ID = del.ID)
The catch is that in the outer query you should not use del.FLAG<> R because it is arrived through join with multiple tables, so if we include del.FLAG<> R, then it is repeating the logic in the inner sub-query in a reserve fashion.The catch is that in the outer query you should not use del.FLAG<> R because it is arrived through join with multiple tables,
Clarification - I have put FLAG = R so as to present the problem simply. Actually the selection criteria (which will replace FLAG = R) results from a multiple table join.
To put FLAG <> R in outer query would be to replicate the multi table join which I don't want -

O.k I have posted couple of problems here. But the latest one is as follows
I trying to pass a Stiring Array from Java function to my native method. the native function in turn invokkes another function that takes a char [][] as its parameter. My native function basically converts teh jobjectarray into char [][] and then invoke the other function.
JNIEXPORT jboolean JNICALL
Java_copilotplus_DataTransferTab_GetStatus
(JNIEnv *env, jobject o, jobjectArray fn, jlongArray size)
char szStr[8][33];
int len = env->GetArrayLength( fn );
int i=0;
for( i=0; i < len; i++ )
jobject obj = env->GetObjectArrayElement(fn, i);
jstring str = (jstring)obj;
szStr[33] = (char)env->GetStringUTFChars( str, 0 );
//*file = szStr[i];
BOOL status = Upload(szStr);
return status;
BOOL Upload(char pFileName [][33])
return TRUE;
Now this compiles fine and makes a dll
But when I run my java program it gives me this error
HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
# Error ID: 4F533F57494E13120E43505002D4
What am I doing wrong
Please Help
VaishaliThe problem was that I did not ahve any actual values in the String Array. I was doing like this initially
String []file = new String[8]
and then when i pass file to the dll it was trying to read something which was not there. That's why it was crashing.
But now I put some values in it and then it works fine. -

turn off your phone, then unplug from the usb cable, but leave that cable attached to the computer. Importaint!: Quit Itunes. Then with your phone off, hold down the home button and plug the usb cable into the phone. keep the home button pushed until you see the connect to itunes screen.

Hi, I am new to programming with C # and wondering if
anyone can help me with one thing.
The only thing I got is this array of letters, but need to sort them
int[] letters = { "c", "s", "a", "k", "x", "l", "j" };
and then print and save the array in alphabetical order.
But the thing is that I never have converted the letters to INT wich I
would need to do in order to sort them with bubble sorting and
then convert back to letters to print and save in the right
order.
How will this code / program look like? The whole thing.
Thanks and much appreciated for help!
If you want more information, ill answer as quick is possible!Almost the same code works even for bubble sorting strings. Just use the string.Compare method instead of the > operator:
string[] letters = { "c", "s", "a", "k", "x", "l", "j" };
string temp;
for (int write = 0; write < letters.Length; write++)
for (int sort = 0; sort < letters.Length - 1; sort++)
if (string.Compare(letters[sort],letters[sort + 1]) == 1)
temp = letters[sort + 1];
letters[sort + 1] = letters[sort];
letters[sort] = temp;
And for chars:
char[] letters = { 'c', 's', 'a', 'k', 'x', 'l', 'j' };
char temp;
for (int write = 0; write < letters.Length; write++)
for (int sort = 0; sort < letters.Length - 1; sort++)
if (letters[sort] > letters[sort + 1])
temp = letters[sort + 1];
letters[sort + 1] = letters[sort];
letters[sort] = temp;
Once again, please remember to mark helpful posts as answer to close the thread once you original question has been answered and start a new thread if you have a new question.
Thank you, and i got a few more questions about this before ill mark this thread as answered.
That codes u just sent me, whats the different between them, the string and char? They almost
look the same except the string and char part.
And then im wondering, how will i write down so i can see the results when im debugging it?
Is it with Console.Write or WriteLine? I can't remember. -

Remember to use the full name of the class in your import statement. And make sure whatever jar file it lives in is included as part of the classpath you use when compiling the program. -

Im stuck with this problem. I have lots of strings each linked with
another string value. I want to store all of them somehow and then sort them out alphabetically while retaining the link between them and the second string value.
basically I have a set of string values called displayname which i want to sort alphabetically and then display. Each display name is linked to another string called featureobjectcode. When i sort and display them i want that link between the two string to be there so that i can display the string name and the corresponding featureobjectcode.can u demonstrate its implementation by showing me an example of how the code would look like?

Updated Apple software iPhone driver, still stuck with my bricked iPhone!
I downloaded the newly released driver from apple this morning, it didn't help at all! HELP!!!!!!!!!
Hey BuePod,
What the guy meant my "...kick the iphone out of recovery mode..." please read below & I had included a link below to his comments;
"To kick the iPhone out of recovery mode following the downgrade you’ll also require Umbrella, handy little app which you can obtain from my site here (Umbrella-4.00.80.zip) or direct from the authors iPhone firmware site. I didn’t allow it access through my firewall (tries to save SHSH blobs, by design, on a remote server – not required to kick out of Recovery Mode). This simple app has the advantages of not requiring additional DLLs or other files installing, functions on x32 and x64 systems and not attempting to do anything untoward to your system."

Stuck with the apple and the scrolling gear while booting
Hi there
i am using my mac for more than 2 years , i did not format it or even fix any thing into it but now something bad happend...
accdentaly my genius friend preesed the power putton for more than 5 seconds to start up the computer and i heared a sound and a the normal flashing light under the track pad and suddenly i was stuck with the apple gray booting screen and the scrooling gear and the computer does not go further .. i left for 2 hours and it still stuck with the same screen ... try to restart do any thing no results also ...
NOTE: THE BIG PROPLEM IS THAT I PUT A PASSWORD FOR THE FRIMWARE AND I FORGOOT IT SO I CAN NOT USE THE FOLLWOING:
1-the ability to use the "C" key to start up from an optical disc.
2-the ability to use the "N" key to start up from a NetBoot server.
3-the ability to use the "T" key to start up in Target Disk Mode (on computers that offer this feature).
4-Diagnostic volume of the Install DVD.
5-mode by pressing the Command-S key combination during startup.
6- a reset of Parameter RAM (PRAM) by pressing the Command-Option-P-R key combination during startup.
Requires the password to use the Startup Manager, accessed by pressing the Option key during startup (see below).
7- Safe mood.
8-Single mode acsses and the other one i forrgot its name.
SO I FIGURED THERE IS NO WAY BETER THAN THE PRIVIOUS WAYS TO SOLVE THE PROPLEM
IF YOU HAVE ANY IDEAS OR ANY THING SO I CAN FIX THIS THING ?
Thanks in advance >>>
iBook G4 Mid 2005 Mac OS X (10.4.8)I was mistaken about the PMU..with a little more digging I found that Open Firmware password can be removed if you change the amount of memory installed.
I found this info here: http://archive.macosxlabs.org/documentation/firmwaresecurity/faqs/faqs.html#remove_passwordprotection
The following is a link from Apple's site to download the user's manual for your iBook:
http://manuals.info.apple.com/en/iBookG4(Mid2005)_UsersGuide.pdf
It provides the instructions to add or remove memory from the machine. If you do have additional memory installed then you'll be able to remove the memory, and reset the PRAM, that way your password is gone. Hopefully from there we can figure out and fix your startup issue.
