Need Help with BI Beans Sample Programs
I am trying to use the print and export functions that are described in the BI Beans sample program. I need to make a small change and don't know how to do it. I would like to open the print or export page in a new window instead of on top of the current page. Any ideas on how to do this? Thanks.

I need help with TV Capture Card program
Hello,
I want to create a JAVA program so I can schedule that the recording with my TV Capture Card begins in x seconds.
Now to start a recording, you must press Ctrl+M and to stop an recording you must click the mouse.
How can I realise that a Java application can "press" Ctrl+M. I have to create an timer, that must be do-able... but I don't know how the program can simulate the pressing of Ctrl+M. I also need to know how the Java program can do a mouse click for me to end the recording.
Thanks in advance for helping me.
Chris.Thank you... I think this was exactly what I needed.

I need help with the Bon Scott program
Help me! I am learning Java from the book, "Teach Yourself Java through Osmosis" and I am having trouble with the Bon Scott program. Everytime I run it, which has been ca. 2 billion, it prints out, "Some balls are held for charity and some for fancy dress, but when they're held for pleasure, they're the balls that I like the best." It then proceeds to get pissed and finally vomits.
Any suggestions ?What color is the vomit? That is, exactly what does it do when it gets pissed and vomits?

Need help with a cash register program.
I'm a noob at JAVA, but having fun with i so far! I was wondering if anyone could help me with a school project I need to get done. I've done most of the work, but I can't get it to not display when I have zero results. What I mean is that the project requires you to create a cash register program that gives you change in 20's, 5's, and 1's for a hundred dollar bill. I get it to display the results, but if there are zero of any category, like in the last problem, I can't let it show. Could someone please help! Thank you in advance! Here's what I have so far (sorry about the rapidshare download ^_^;).
[http://rapidshare.de/files/39978938/project.java.html]Zack,
The user should not see the line: 0 $5 bill(s)Then you need to detect the situation where no five dollars bills are included in the change, and suppress the output of that line.
I can read your mind... it's going something like "yeah well righto smartass, I knew that allready... my question was _HOW_ to make that happen...
And my answer to that is "I'm not telling you"... well, not straight out anyway, coz you'll actually learn more if your struggle a bit (but not too much) yourself...
So... I suggest you (at least) read through [this page|http://java.sun.com/docs/books/tutorial/java/nutsandbolts/if.html] on the +if+ statement, and maybe even try out the examples, which should (I imagine) take maybe half an hour or so. "Selection" is an absolutely core programming construct... and the concept is common to every programming language ever (AFAIK) invented... meaning that you will really struggle until you "get" the +if+ statement... so that half hour would be time well spent.
When you've got +if+ concept onboard, you can attempt to apply it to your immediate problem, suppressing those annoying fivers! Have a go yourself, if get really stumped than post a _specific_ question here about the bit that's stumped you.
I know it can be frustrating... but that just hightens the little thrill you get when you "get it".
Cheers. Keith. -
I need help with a lab from programming.
I need the following tasks implemented in the code I wrote below. I would really appreciate if someone could achieve this because it would help me understand the coding process for the next code I have to write. Below are the four classes of code I have so far.
save an array of social security numbers to a file
read this file and display the social security numbers saved
The JFileChooser class must be used to let the user select files for the storage and retrieval of the data.
Make sure the code handles user input and I/O exceptions properly. This includes a requirement that the main() routine does not throw any checked exceptions.
As a part of the code testing routine, design and invoke a method that compares the data saved to a file with the data retrieved from the same file. The method should return a boolean value indicating whether the data stored and retrieved are the same or not.

How do I get it to save?
Also, in the last post I had the write method commented out, the correct code is:
System.out.printf ("\nHere are all your Social Security Numbers stored in our database:\n");
System.out.printf ( "\n%8s%32s\n", "Database Index", "Social Security Numbers" );
System.out.println ( arrayStorage );

out.write( "what goes here ?" );
out.close ();

// File already exists

Need help with a vowel reading program :(
Hi, im trying to create a program that does the following:
"a program that reads a list of vowels (a, e, i, o, u) and stores them in an array. The maximum number of vowels to be read should be obtained from the user before beginning to read the vowels, however, the user may cancel the reading of vowels at any time by entering '#'. The algorithm should then count and display the number of times each vowel appears in the array. Finally the algorithm should also output the index in the array where the each vowel first appeared or a suitable message if a particular vowel is not in the array at all."
It says to store the input in an array so I've probably started all wrong :( but any help at all would be greatly accepted.
Im trying to go through it doing one method at a time but im having trouble with the reading input method
the 1 error i get is marked with ***.
Is it that I need to do a for loop first to find the length of the string?
import java.io.*;
import javax.swing.JOptionPane;

public static String readIn()
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));

max = input.readLine();
int total = Integer.parseInt(max);
catch(Exception e) {System.out.println("invalid");}
do
sentence = JOptionPane.showInputDialog("Enter a sentence, ("+max+" characters maximum): ");
int ind = sentence.length();
}while(ind <= max); //*** the arrow is under 'ind' and says "cannot resolve symbol"
return sentence;

String data = "";
data = readIn();
}Thanks.thanks for your reply Paul ^^ , but im still having trouble with that part of the program :(
Its saying "operator <= cannot be applied to int,java.lang.String" (Ive marked in asterisks)
Also i've add the rest of the program code, but in the calcPrint method i am having trouble understanding some of it (some of the code was used from another program) and it would be great if someone could show me a more simplier way of coding the same thing? even if its more typing, i just want to understand it better.

I have a problem with a grey text box. It writes and says all i do. For example: When i now write it says all the letters one for one. If i open a new rogram it says so. If i click on something it gives me information about it. I can click the box and drag it, but dont close it. I have restarted the computer and closing all windows and programs. It just popped out when i was pressing some buttons on the mac. I think it is a easy way to fix it, but i cant find out what it is named and search for it. I think it is made for help and i did not download anything to get it. If i change user on the mac it does go away when I am on the other user, but i really want to keep the one i have because off all the settings and programs i have.
Please reply if you know anything about this.
This is a printscreen of the box, the language is Norwegian if someone wonder...
It is really annoying, I hope someone can help me out.Oh thanks alot! Really happy that people take the time to answer my `noob`questions! Would not find that out by my own.
Thanks! -
Need help with running a Java program on Linux
I am trying to get a Java program to run on a Linux machine. The program is actually meant for a Mac computer. I want to see if someone with Java experience can help me determine what is causing the program to stall. I was successful in getting it installed on my Linux machine and to partially run.
The program is an interface to a database. I get the login screen to appear, but then once I enter my information and hit enter the rest of the program never shows, however, it does appear to connect in the background.
Here is the error when I launch the .jar file from the command screen:
Exception in thread "main" java.lang.IllegalArgumentException: illegal component position
at java.awt.Container.addImpl(Unknown Source)
at java.awt.Container.add(Unknown Source)
I am not a programmer and I am hoping this will make some sense to someone. Any help in resolving this is greatly appreciated!Well, without knowing a little bit about programming, and how to run your debugger, I don't think you're going to fix it. The IllegalArgumentException is saying that some call does not like what it's getting. So you'll have to go in an refactor at least that part of the code.

Need help with solving the (basic) programming error
I'm reaaaaaaaaaally new to Java and programming in general. I've been glancing through my older brother's old stuff (he's back at Uni!) and I've taken an interest.
Anyways, so I'm trying to finish this really simple program cause I wanna wow some friends ("wow" = "haha we've done this before a gazillion times") but I can't seem to solve this "incompatible lines" bug in the code, specifically line 24. I've been looking at it for exactly 4 hours!! Programming in Java 1.6.
Thanks for the help!! :)

}Having said that, it is nontraditional to use Scanner like you are using it. There is no way to reuse it in order to get more input. Better would be something like:
System.out.println("What size of pizza do you want?");
Scanner scan = new Scanner(System.in); // create the scan variable
String size = scan.nextLine(); // now use the scan variable
System.out.println(size);Also, when posting your code, please use code tags so that your code will be well-formatted and readable. To do this, place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
// your code block goes here.

Need help with java.nio.socket program.
Can someone please help me here? I am trying to create a class that listens on a socket for an incoming connection, but I am getting the following error on compile:
SocketIn.java:48: incompatible types

// Create a non-blocking server socket.

serverChannel.configureBlocking(false);
// Use the host and port to bind the server socket.
InetAddress inetAddress = InetAddress.getLocalHost();
InetSocketAddress socketAddress = new InetSocketAddress(inetAddress, intPort);
serverChannel.socket().bind(socketAddress);
// The selector for incoming requests.
Selector requestSelector = SelectorProvider.provider().openSelector();
// Put the server socket on the selectors 'ready list'.
serverChannel.register(requestSelector, SelectionKey.OP_ACCEPT);
while(requestSelector.select() > 0){
System.out.println("Connection Accepted...");
// A request has been made and is ready for IO.
Set requestKeys = requestSelector.selectedKeys();

while(iterator.hasNext()){
SelectionKey requestKey = (SelectionKey)iterator.next();
// Get the socket that's ready for IO.
ServerSocketChannel requestChannel = (ServerSocketChannel)requestKey.channel();
// This shouldn't block.
Socket requestSocket = requestChannel.accept();
inBuffer.clear();
requestSocket.read(inBuffer);
inBuffer.flip();
Charset charset = Charset.forName("ISO-8859-1");
CharsetDecoder decoder = charset.newDecoder();
charBuffer = decoder.decode(inBuffer);
iterator.remove();
}Well its been about a month and a half so I guess you have your answer. In case you don't...
// This shouldn't block.
Socket requestSocket = requestChannel.accept();
The problem is quite simple. The ServerSocketChannel.accept() returns a SocketChannel. (Channel -> Channel).
You can get access to the socket using the SocketChannel.
SocketChannel requestSocketChannel = requestChannel.accept();
Socket requestSocket = requestSocketChannel.socket();
But you don't need the socket to read and write. -
Need help with a magic square program
Hi, I have to write a code that prints out first 10 magic square numbers
-- magic square numbers: numbers that is a perfect square and sum of consecutive integers (like 36 -- 6 squared or sum of 1 to 8)
here's my code:
public class Loop {
public static void magicSquare ()
long inc = 0;
long integer = 0;
long total = 0;
for (int square =1; square>0; square++)
total = square*square;
int sum = 0;
for (int i = 1; i>0; i++)
if (sum<total){
sum += i;
else if (sum==total){
System.out.println("Magic Square is: " + total);
break;
else {
break;
I have a simple seperate driverMerge - you have two lists, a list of squares (implicit list, you just remember the last square and what you need to increment to the next one), and a list of triangles (sums of n consecutive numbers starting at 1 are triangular numbers).
As long as the head of one list is below the other you increment it. When the two heads coincide you have a squareTriangle.
It ran pretty quickly on my machine, so it is probably not worth telling you how the whole thing can be reduced to pells equation and how the numbers represent successive rational approximations to the square root of 8. Continued fractions rule and are where you would go if you needed to go faster than this - but 0 seconds (which has to be a lie caused by round off error) seems good enough
static void spewSquareTriangles(int n){
long q = 0; // first square
long t = 0; // first triangle
long iq = 1;
long it = 1;
for(int i = 0; i<n;){
if(q == t){
System.out.println(i + ": " + q);
q += iq; iq += 2; // squares increment by odd numbers 1+3 = 4;+5 = 9;+7 =16 ...

Need help with API and sample code for checking a user's rights on a folder
Hi All,
I am working on an UCM integration where user supplies a folderpath (ucm folders), and a file is later uploaded to this location.
Since a user can provide a folderpath where he has only Read Access or no access at all, we are trying to work out a way to pre-check his permissions on the folder.
Since we have Entity Security enabled, we have 5 security fields to rely on Account, Security Group, User Access List, Group Access List, Role Access List.
Writing custom code for this security check is second on our agenda.
Firstly, we wish to know the API and sample code that typically performs this Security Check in UCM.
We could find intradoc.shared.SecurityUtils which has methods to check security on SGroup and Account, but we couldn't find anything for:
1) Overall security check
2) ACL security check on top of sgroup and account security checkAny ideas anyone?!
I am looking forward to some pointers here. :(
