Help needed on to write a program on connecting to data source

I would to program a class that connect to data source without any manually configure.
Is there other way that i could use intsead of using
db = DriverManager.getConnection("jdbc:odbc:Driver={SQL Server};Server=MyServerName;Database=MyDataBase","","");
My project requires me to use JDBC-ODBC Bridge on connecting to data source on client machine
Is there any other way?

Oh, oh,
why???
It's so simple to do a JDBC connection using the same connection params, which you use for your VB program's connnection.
If your VB prog uses a system or user DSN configured via control panel, then use the same DSN in your Java prog.
Dear karentan,
you have just the same question now active in 4 or 5 different topics. And I and others have not been able to understand what really is your problem, I fear.
Would you please do two things:
1) Start a new topic (yes, another one!) and tell us there what exactly is your problem. What do you want to do?
Not: is it possible ... but: I want ...
2) Go to all the other topics you spreaded here and post the link of your new topic there, so that the poor people who try to answer your 5 (always the same) questions know that they can spare their time.
Please, hold this forum useful!
And let us come to the point that you are helped and we are glad!

Really need help on how to write this program some 1 plz help me out here.

i am new to java and i confused on how to be writing this program.
i have completed the Part 1 but i am stuck on Part 2 & 3 so it would would be really great if any 1 could help me out on how to write the program.
Part I
An algorithm describes how a problem is solved in terms of the actions to be executed, and it specifies the order in which the actions should be executed. An algorithm must be detailed enough so that you can "walk" through the algorithm with test data. This means the algorithm must include all the necessary calculations.
Here is an algorithm that calculates the cost of a rectangular window. The
total cost of a window is based on two prices; the cost of the glass plus the cost of the metal frame around the glass. The glass is 50 cents per
square inch (area) and the metal frame is 75 cents per inch (perimeter).
The length and width of the window will be entered by the user. The
output of the program should be the length and width (entered by the user)
and the total cost of the window.
FORMULAS:
area = length times width perimeter = 2 times (length plus width)
Here is the corresponding algorithm:
read in the length of the window in inches
read in the width of the window in inches
compute the area
compute the cost of the glass (area times 50 cents)
compute the perimeter
compute the cost of the frame (perimeter times 75 cents)
compute the total cost of the window (cost of glass plus cost of frame)
display the length, width and total cost
The next step would be to "desk check" the algorithm. First you would need to make up the "test data". For this algorithm, the test data would involve making up a length and a width, and then calculating the cost of the window based on those values. The results are computing by hand or using a calculator. The results of your test data are always calculated before translating your algorithm into a programming language. Here is an example of the test data for the problem given:
length = 10
width = 20
area = 200, glass cost= 100.00 (area times 50 cents)
perimeter = 60, frame cost = 45.00 (perimeter times 75 cents)
total cost =145.00
Once the test data is chosen, you should "walk" through the algorithm using the test data to see if the algorithm produces the same answers that you obtained from your calculations.
If the results are the same, then you would begin translating your algorithm into a programming language. If the results are not the same, then you would attempt to find out what part of the algorithm is incorrect and correct it. It is also
necessary to re-check your hand calculations.
Each time you revise your algorithm, you should walk through it with your test data again. You keep revising your algorithm until it produces the same answers as your test data.
?Now write and submit a Java program that will calculate the cost of a rectangular window according to the algorithm explained. Be sure to prompt for input and label your output.?
Part II
Write, compile and execute a Java program that displays the following prompts:
Enter an integer.
Enter a second integer
Enter a third integer.
Enter a fourth integer.
After each prompt is displayed, your program should use the nextint method of the Scanner class to accept a number from the keyboard for the displayed
prompt. After the fourth integer has been entered, your program should calculate and display the average of the four integers and the value of the first integer entered raised to the power of the second integer entered. The average and result of raising to a power should be included in an appropriate messages
(labels).
Sample Test Data:
Set 1: 100 100 100 100
Set 2: 100 0 100 0
Be sure to write an algorithm first before attempting to write the Java code. Walk through your algorithm with test data to be sure it works as anticipated.
Part III
Repeat Part lI but only calculate the average, not the power. This time, make sure to use the same variable name, number, for each of the four numbers input. Also use the variable sum for the sum of the numbers. (Hint: To do this, you may use the statement sum = sum + number after each number is read.)
For Part 1 this is what i got
import java.util.Scanner;
public class Window
     public static void main(String[] args)
          double length, width, glass_cost, perimeter, frame_cost, area, total;
          Scanner keyboard = new Scanner (System.in);
          System.out.println("Enter the length of the window in inches");
          length = keyboard.nextInt();
          System.out.println("Enter the width of the window in inches");
          width = keyboard.nextInt();
          area = length * width;
          glass_cost = area * .5;
          perimeter = 2 * (length + width);
          frame_cost = perimeter * .75;
          total = glass_cost + frame_cost;
               System.out.println("The Length of the window is " + length + "inches");
               System.out.println("The Width of the window is " + length + "inches");
               System.out.println("The total cost of the window is $ " + total);
     Enter the length of the window in inches
     5
     Enter the width of the window in inches
     8
     The Length of the window is 5.0inches
     The Width of the window is 5.0inches
     The total cost of the window is $ 39.5
Press any key to continue . . .

Also use the variable sum for the sum of the numbers. (Hint: To do this, you may use the statement sum = sum + number after each number is read.)Man, this specification writes itself. Sit down and start coding.
One bit of advice: Nobody here takes kindly to lazy, stupid students who are just trying to con somebody into doing their homework for them. If that's you, better have your asbestos underpants on.

How to Write Log Message in a XML Data Source Report

Hi Friends,
Can anyone help me out what is the process of writing a log file in the XML Data Source Report. for eg: in Plsql we use FND_LOG.PUT_LINE to print the Log message in the Concurrent Request Output. in the similar manner, when we develop a report using XML, where we write Coding in XQuery of XML, what is the process need to follow to print the logs for the XQuery.
Any inputs/Suggestion on this Highly appreciable.
Thanks in advance.

Create an RMI application (for example) that writes the log, and let all logging calls call that remote application.
Something like that is the only feasible way that doesn't require you to have a drive on the remote machine mapped to the local one (which causes its own problems as you could have multiple simultaneous write attempts...).

Help needed in executing pl/sql programs

hi all
iam new to PL/SQL programming
i have installed oracle 9i
iam trying to practice some sample pl/sql programs
i have opened oracle 9i and typed these commands
sql>ed sum
then a notepad opens where i type my pl/sql program and save it and then return back to oracle 9i and type this
sql>@ sum
then my pl/sql program gets executed.......but iam not getting any output
its comig as procedure implemented succesfully
is it compulsory to open notepad to execute pl/sql progams or we can direclty type the programs in oracle 9i
please help in this matter ASAP
Regards

Yes, you can type the program directly at the SQL prompt, but editing will be a bit difficult.
You should use some good editor that allows you to edit properly and then run like you did.
You need to do:
SQL> set serveroutput onbefore running your program to see dbms_output messages.

Help needed on a TicTacToe java program

I am very new to java and our teacher has given us a program
that i am having quite a bit of trouble with. I was wondering if anyone could help me out.
This is the program which i have bolded.
{You will write a Java class to play the TicTacToe game. This program will have at least two data members, one for the status of the board and one to keep track of whose turn it is. All data members must be private. You will create a user interface that allows client code to play the game.
The user interface must include:
�     Boolean xPlay(int num) which allows x to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
�     Boolean oPlay(int num) which allows o to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
�     Boolean isEmpty(int num) will check to see if the square labeled by num is empty.
�     Void display() which displays the current game status to the screen.
�     Char whoWon() which will return X, O, or C depending on the outcome of the game.
�     You must not allow the same player to play twice in a row. Should the client code attempt to, xPlay or oPlay should print an error and do nothing else.
�     Also calling whoWon when the game is not over should produce an error message and return a character other than X, O, or C.
�     Client code for the moment is up to you. Assume you have two human players that can enter the number of the square in which they want to play.
Verifying user input WILL be done by the client code.}

Help needed creating a linked list program

I have been trying to create a linked list program that takes in a word and its definition and adds the word to a link list followed by the definition. i.e. java - a simple platform-independent object-oriented programming language.
the thing is that of course words must be added and removed from the list. so i am going to use the compareTo method. Basically there a 2 problems
1: some syntax problem which is causing my add and remove method not to be seen from the WordList class
2: Do I HAVE to use the iterator class to go thru the list? I understand how the iterator works but i see no need for it.
I just need to be pointed in the right direction im a little lost.................

To answer your next question "+how do I add things to my list then?+": Well, you need to create an instance of your WordList class and call the add(...) method on that instance.
Here's an example of instantiating an object and invoking a method on that instance:
Integer i = new Integer(6); // create an instance of Integer

use boolean operator in while loop
what do do??

so can some 1 help me"Help" as in provide workable code? They might - you did all right in your last
thread. Personally, though, I doubt you're much helped by this.
Start by reading the description of what your code must do. Make sure you
understand the description - perhaps by explaining it in your own words to someone
else. If they don't understand then you don't understand: not in any sense
that matters.
Then proceed to write some code. The first sentence of the description you posted
makes a good starting point. Write some code that compiles and does this.
Make sure you understand what each line does before moving on.
If you get stuck post some code and an actual question. If there is a compiler error,
copy paste and post the actual error you can't understand and say which line it refers
to. If your code compiles but has unwanted, unexpected or mysterious results,
say what it does and what you were expecting, or wanting.
Hope that helps.
(My apologies if your native language is not English, but really. Use a
dictionary - online or, better, in paper form. Eschew abbreviations. Read what you
post aloud or, as above, to someone else who can tell you if it makes no sense.)

Help needed in 8i Lite Replication Programming

Hi:
I am currently doing a prototype of using Oracle Lite 8i replication service. I am using the Oracle Replication OLE Control (shipped with 8i Lite) in a VB program. I just tried to connect to my local 8i Lite database by using the API, here is the code:
Private Sub Form_Load()
Dim Obj As Object
Set Obj = CreateObject("POLite.Repsvr8")
Dim rcode As Boolean
rcode = Obj.StoreConnectionOpen("scott", "tiger", "POLITE")
End Sub
And here is the error I got:
In a message box with a caption of "POLite Replication Server", it says "repcb8.dll -- could not be loaded (126) "
Can anybody from Oracle community tell me what this message all about? And if you guys have any sample replication VB code, I would appreciate if you guys can share with me.

Hello,
we had the same problem as you did and we couldn't find the repcb8.dll file on the installation CD.
You have to make a copy of your \ORACLE_HOME\BIN\olrep840.dll file.
(or if you are using an older version olrep835.dll/olrep836.dll). Then you have to RENAME the copy of olrep840.dll to repcb8.dll.
Perhaps it will now ask for another file. Repeat the same process for this file also (rename a copy of the olrep840.dll to this file).

Help needed for MySQL 5 database DSN less connection with Oracle reports

Hi,
I am using Oracle Develper Suite and java (J2EE) for my application. I am using MySql 5 as database tool. I want to use Oracle reports of Oracle Develper suite. I have created some reports by first creating system DSN for MySql database and then connect Oracle reports to that DSN by "jdbc:odbc" connection string provided in Oracle Report developer wizard. This is working fine.
I want to generate reports without creating system DSN (DSN less) so that i can use my application on any computer without creating DSN for Oracle Reports. I am deploying my application on OC4j as "EAR" file.
Help in this regard will be highly appreciated.
Regards.

Using an 8i client, you will need to configure the tnsnames.ora file with appropriate connection information if you are using local naming. If you are using host naming or something like an Oracle Names server to resolve TNS aliases, you can skip the tnsnames.ora configuration. A default installation of the Oracle client, though, will probably be using local naming.
If the tnsnames.ora file is configured, or you have configured an alternate way of resolving TNS aliases, you should be able to use the connection string
DRIVER={Oracle ODBC Driver};DBQ=<<TNS alias>>;UID=system;PWD=managerIf you wanted to move to the 10g client (the 10g Instant Client could be useful here), there are some streamlined naming methods that could be used instead of configuring the tnsnames.ora file.

Help needed with printer settings for wired ethernet connection

I'm hoping someone can help me with a network printing issue. I have a large format color laser printer (Tektronix Phaser) and since moving to OS 10.6 I can't figure out how to configure the printer so that the system sees it. I have a simple wired ethernet network with a couple of Macs and a couple of printers. All devices are connected via a switch. When using earlier OSs I was able to connect to the Phaser using Ethertalk. Obviously this is no longer supported and I can't figure out how to set the printer so the OS can see it. I have lots of options which can be turned on or off and in some cases set up in other ways: Ethertalk, IPX, Netware, TCP/IP, DNS, LPR, HTTP and remote internet printing, I've tried messing with these but the result is always the same--system doesn't see the printer. Currently Ethertalk is on, IPX and Netware are off, TCP/IP is on, DNS and LPR are on, as are AppSocket, HTTP, FTP and remote internet printing. I can change the IP address but no matter what address I've tried I cannot ping the printer. (I'm using a Gutenprint driver for this printer.)
I don't really know enough about all this to get anywhere and I haven't been able to find help anywhere even from tech friends. Xerox won't help me and neither will Apple. Any help would be appreciated. I can supply more detail on specifics where necessary. Thanks, Bob

Old Phaser models may becoming more and more difficult to use, but you can give this a try.
1. Configure the printer via front panel to use TCP/IP and enable DHCP if it's supported. If not then you will need to configure an IP address for the printer together with your local network's mask, and gateway IP address. Except for the first the others will be provided by opening Network preferences to see what those settings are. The printer's IP address needs to be set somewhere within the range of IP addresses your router provides locally.
2. You need the PPD file required for your printer. If you have the Phaser driver installer you can use it to install the PPD or you can extract the specific PPD from the installer package. This part is tricky because I don't know where you may find the driver now if you don't have the installer. The older installers can be accessed through the Finder by selecting the package then CTRL- or RIGHT-click and select Show Package Contents from the contextual menu. You can then rummage through the package to search for the PPD for your printer. Then navigate to the /Library/Printers/PPD/Contents/Resources/ folder and drop the PPD file inside.
3. Open Print & Fax preferences and click on Add [+] to add a new printer. Click on the IP icon in the toolbar. Select Line Printer Daemon - LPD from the Protocol drop down menu. Input the IP address you assigned the printer in the Address field. You can file in the optional fields that follow. Then from the Print Using drop down menu locate the listing for your printer and select it.
