I Can't Find The Problem!! pls help (ONLY IF U HAVE SOME FREE TIME)

Question

I'd like to post some code because I cant see the problem, maybe somebody else will see it. Just take a little look if u see some detail let me know pls.
I have a class word, wich is actualy a representation of a word in some text
public class Word {
int timesInText; //how many times this word is in the text
//A vector with the lines were the word appears
public Vector<Integer> lines = new Vector<Integer>();
public String word; //The word we are representing... Very creative Isn't it?
//The lines were the word appear in a string in this format : , line, line, line...
StringBuffer Stringlines = new StringBuffer(":");     
public Palabra(String word) {
this.word = word;          
timesInText=1;
public void wordFinded(int linea) {        
lines.add(linea);     
Stringlines.append(", " + linea);     
timesInText++;     
public String toString() {        
String var = word + ": " + Stringlines.toString();
return var;
}//End of the word class
I have a class main, wich is a window with the logic of the program, notice that
I'll provide only the necesary thing to understand my problem in order to make
my post shorter. The words I read can't have duplicates but I must say in wich
lines the duplicates are.
public class main{
Vector<Word> words = new Vector<Word>(); //A vector for all the words in text
JText area = new JTextArea(); //The JTextArea of my window
public void getWords(){
JFrame wordsInText = new JFrame("Word Search:");
JTextArea wordsArea = new JTextArea("\tResult :");
wordsInText.getContentPane().add(new JScrollPane(wordsArea));
boolean alreadySeen;
String text = area.getText();
String line;
String word;
Word wordBeingRead;
int lines = 0;
BufferedReader br = new BufferedReader(new StringReader(text)); //To read complete text
while ((line = br.readLine()) != null)
     lines += 1;
StringTokenizer st = new StringTokenizer(line, " "); //But line by line
while (st.hasMoreTokens())
alreadySeen = false;
word = st.nextToken();
wordBeingRead = new Word(word);
Iterator iter = words.iterator();
if(!iter.hasNext()) //The first word! save it
words.add(wordBeingRead);
else //Yeah... not the first word... Check it...
Iterator iterAux = palabras.iterator();
while(iterAux.hasNext()) //Check if it's already defined
Word p = (Word) iterAux.next();
if(wordBeingRead.word.equals(p.word)) //It is already defined...
wordBeingRead.wordFinded(lines); //I got one on line (lines)
alreadySeen=true; //Yes! It's already seen
if(alreadySeen==false) //If it's already seen wont get in here
words.add(wordBeingRead); //A new word! Let's save it
Iterator iter = palabras.iterator(); //Ok I saved all the words, time to print them
while(iter.hasNext())
     wordBeingRead = (Word)iter.next();
     wordsArea.append("\n" + WordBeingRead.toString()); //Put them over here
     wordsInText.setSize(400, 400);
wordsInText.setLocation(100, 75);
wordsInText.setVisible(true); //Yes! show them
}catch(Exception e){
label.setText(e.getMessage()); //If anything goes wrong
}//End of the class main

Ok, sorry about that.
Post your code between code tags (use the code button when you post a reply).I'm new in the forum and the tags doesnt seem to work with netscape, will use IE next time.
you should not have a main class. You should have a main method inside a class eg:The original name of the class is Ventana, but you can actually name a class main.
Also, your constructor should have the same name as your class eg:The constructor in the word class it's written like that because I translated the code to english so that it could be more simply to understand.
4. If you don't get errors tell us what you expect your code to do and what it IS actually doing.Ok I'll give you a sample input and output:
INPUT:
"I am sorry for not posting correctly
I will make sure this wont happen again
I will be a good user"
OUTPUT I'm getting:
I: :
am: :
sorry: :
for: :
not: :
posting: :
correctly: :
will: :
make: :
sure: :
this: :
wont: :
happen: :
again: :
be: :
a: :
good: :
user: :
OUTPUT I would love to have:
I: 1, 2, 3
am: 1
sorry: 1
for: 1
not: 1
posting: 1
correctly: 1
will: 2, 3
make: 2
sure: 2
this: 2
wont: 2
happen: 2
again: 2
be: 3
a: 3
good: 3
user: 3
I just noticed that I get the double : : Because I do it twice... ^^
Thanks for the recomendations, and I'm sorry, totally my fault, I mean it.
