Be specific, which errors do you have, where are you stuck, ... ?
Anyway, the code you pasted doesn't make any sense (misplaced braces, no name for the class, no body for the main function, all the code is in your class and not in a function, ...). If this is your real code (but I can hardly imagine this), then nobody here will be able to help you: you are lacking the most basic skills in Java. I suggest you start from the begining: learn the syntax (from a good book, it is always the best).

If it compiles then I suggest you Debug it line by line because there may be a problem with your logic.

What's the best solution for doing non blocking sockets in Java? The Socket class in and of itself doesn't support this. I'm aware of NIO but have heard rumors that's not very good or perhaps tricky to use?
I found Apache's MINA (http://mina.apache.org[^]) which looks promising, but wondered what people here have used.

Jim,
the easiest is to create the ServerSocket listening on it's own thread. The listening thread is blocked, but you can still call the close() method.
This will cause a SocketException to be thrown on the listening thread to allow for graceful exit.
See Class:ServerSocket[^] for details.
Panic, Chaos, Destruction.
My work here is done.

Have you actually researched anything?
Anyway, look at BufferedImage.[^]
If you can't find what your looking for on there then you should choose something else to do.

what would be the use of the strong tokenizer?

It breaks a sentance into words, is a simple way of putting it.
Have a look at the Documentation.[^]

Hello,
I'm new to JSP but have experience with .NET, and was wondering if someone could help me with this.
I am trying to encode an ID value that is being passed in a querystring. This value (assuming it isn't null) will then be printed out to a page. In .NET I'd use the HttpUtility.HtmlEncode method but was wondering if there is something similar in Java. Please find an example of my code below.
<param name="movie" value="swf.swf<%= request.getParameter(" id=") != null ? "?id=" + request.getParameter("id") : "" %>">
</param>
Any advice you could give me would be greatly appreciated.

Hi all,
i want to write a java script which will remove duplicates in html page.
scenario:- i am having html page that can be acessed by all my team members when ever they want to write some thing new they will just write in webpage directly in webbrowser and they will click the submit button.
i want to write a java script such that whenever they click on that submit button it should show a warning message and then delete if the data that is newly added already exists.
Thanks in advance.

You are in the wrong forum.
What you want is complicated. JavaScript cannot access your server database, so it cannot decide if "data already exists".
Do you even have a server database? Or was your idea that every user is actually modifying the web page that serves as the input form?
Ideally, you have some sort of web server that allows updates to a database and sends dynamic web pages out to users. If you don't know what I am talking about, stop here and get a web developer into your office.
Now, you have two choices: submit the form to the web server and have JavaScript check the response message in an OnLoad event handler, OR use AJAX to do the same thing without refreshing the page.
The second option is much nicer looking, but a little more complex.
Again, if you don't know what I am saying, you need a person sitting in your office who does. You will not be able to do this yourself without a LOT of research.
Don't let my name fool you. That's my job.

I can't find the nullpointer error I'm having with netbeans and it's getting to me, any help would be appreciated. Below is my code of a class that will evaluate a RPN expression given in prefix form. I included one of the methods. they all look the same except either it has .minus .plus .times. The stack declared, can only hold Object types which is why the casting was neccessary. I know a little bit about Generics but I can't use them. I really, would appreciate any help. Thanks in advance hopefully.
public class PrefixEvaluator
{
private final int MAX_SIZE = 60;
private BufferedReader stdin;
private Stack evaluate = new Stack(MAX_SIZE);
private boolean valid = true;
private Object answer1 = new Object();
void run() throws IOException
{
String toEval = stdin.readLine();
while( toEval != null && valid )
{
Object op1 = new Object();
Object op2 = new Object();
int eqns = 1;
System.out.println( "Raw Expression " + eqns + " is: " + toEval );
ReverseTokenizer equation = new ReverseTokenizer( toEval, " ");
String token = equation.nextToken();
if( token.charAt(0) == '(')
{
evaluate.push( token );
}
else if ( token.charAt(0) == '+' ||
token.charAt(0) == '*' ||
token.charAt(0) == '-' )
{
if( evaluate.isEmpty() )
System.out.println( "Invalid Expression" );
else
{
op2 = evaluate.pop();
op1 = evaluate.pop();
if( token.equals("+"))
addition(op1, op2);
else if( token.equals("-"))
subtract(op1, op2);
else if( token.equals("*"))
multiply(op1, op2);
else
System.out.println( "Invalid Expression" );
}
eqns++;
}
toEval = stdin.readLine();
}
answer1 = evaluate.pop();
}
public void addition( Object op1, Object op2)
{
Fraction operand1 = new Fraction();
Fraction operand2 = new Fraction();
Fraction addAns = new Fraction();
Object answer = new Object();
operand1 = (Fraction)op1;
operand2 = (Fraction)op2;
addAns = operand1.plus(operand2);
answer = (Object)addAns;
evaluate.push(answer);
}
