I'm not an AWT expert, but here's my best guess to the problem...
I'm not sure that the ActionListener is the correct event listener to use here.
I don't think the straight TextArea throws action events, I could be wrong here I mainly have experience with swing.
What event are you trying to react to here? Also is there any reason for not using Swing? Then you can use the JTextArea.
Hope I'm of some help :)

Dear Friends,

Can't find the error on this small code :S

Hi , i've just compiled this code and i can't find what is wrong! :(
The compiler is ok, but the output print its not what i was expect.
If u insert 121 (capicua) the answer is: This number its not a capicua :S
what is wrong?
thanks!!
Note: Don't create another code plz.
import java.io.*;
public class Capicua {
     public static void main (String[] args) throws Exception {
          int digit, num;
          int inverted = 0;
               BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
               System.out.print(" Insert number: ");
               num=Integer.parseInt(br.readLine().trim());
               while(num > 0) {
               digit = num % 10;
               num = num /10;
               inverted = inverted * 10 + digit;
               if(num == inverted) {
                    // to be capicua the number inserted must
                    //be equals to the inverted
                    System.out.println("Its Capicua!");
               }else{
                    System.out.println("This number is not a Capicua!");
}

Please use code tags (see button above posting box) when posting code. It makes it much easier to read.
So, it appears that capicua means palindrome--the number reads the same backwards and forwards. Is that correct?
There are ways of doing this without converting the 121 to a number, but I won't explain that unless you want.
I think your problem is this line:
if (num == inverted)
You have changed "num" within your while loop. Therefore, num is no longer the original input 121.
Try adding println statements like this to watch what happens:
while(num > 0) {
digit = num % 10;
num = num /10;
inverted = inverted * 10 + digit;
System.out.println("digit = " + digit);
System.out.println("num = " + num);
System.out.println("inverted = " + inverted);
}

Where's the error in this code...

the following snippet of code throws a SQLException with a 'Invalid Handle' message.
What's does this 'Invalid Handle' mean? And, which line of code is causing the problem?
try {
//RETRIEVE CITYLIST FROM DB
cityList = statement.executeQuery("SELECT CityCode, CityName FROM CityList");
while (cityList.next()) {
//ADD CODES AND NAMES OF CITIES TO ARRAYLISTS
String code = cityList.getString(1);
String name = cityList.getString(2);
codes.add(code);
names.add(name);
cityList.close();
} catch (SQLException sql) {
System.out.println("2-checkForAvailability.jsp..err->" + sql);
Any help will be appreciated..
regards
Ushanta

Yes, you don't declare the ResultSet inside that try block, so I'll assume that it's a data member of your class. I'd suggest that you make the ResultSet a local variable in that method and not try to hang onto it. Same for the statement:
Statement statement = null;
ResultSet cityList = null;
try
statement = connection.createStatement();
cityList = statement.executeQuery("SELECT CityCode, CityName FROM CityList");
while (cityList.next())
    String code = cityList.getString(1);
    String name = cityList.getString(2);
    codes.add(code);
    names.add(name);
} catch (SQLException sql)
    sql.printStackTrace();
    System.err.println("SQL state: " + sql.getSQLState());
     System.err.println("SQL error: " + sql.getErrorCode());
finally
    try
        if (cityList != null)
            cityList.close();
        if (statement != null)
            statement.close();
    catch (SQLException ignoreException)

Please give the meaning of this code

Hi anyone please give the meaning of the below mentioned modify command code
READ TABLE XKOMV INTO L_XKOMV
              WITH KEY
              KSCHL = 'ZGBC'.
IF sy-subrc = 0.
    XKOMV-KINAK = 'X'.
    <b>MODIFY XKOMV TRANSPORTING KINAK WHERE KSCHL = 'ZFIK'.</b>
ENDIF.
Point will be sure.

Hello Vijaya,
Its reading the Conditiuon table and checking for the condition type ZGBC in the document condition table. If it exists then its makeing the Condition ZFIK as in active. So   During pricing, the system ignores conditions that are valid but not active in this case ZFIK.

What is the error with this code ??

i'm trying to execute the following AS3 code:
var itemsArr:Array = new Array ();
var i:int;
      var loaderAds:URLLoader = new URLLoader();
      loaderAds.load(new URLRequest("ads.txt"));
      loaderAds.addEventListener(Event.COMPLETE, completeHandlerAds);
      function completeHandlerAds(eventAds:Event):void {
          var loaderAds:URLLoader = URLLoader(eventAds.target);
          var varsAds:URLVariables = new URLVariables(loaderAds.data);
            itemsArr = varsAds.names.split(";");
                    for (i = 0; i < (itemsArr.length); i++) {
                            trace("itemsArr, Processing: " + itemsArr[i]);
       var loaderProps:URLLoader = new URLLoader();
      loaderProps.load(new URLRequest(itemsArr[i]+".txt"));
      loaderProps.addEventListener(Event.COMPLETE, completeHandlerProps);
      trace("one: " + itemsArr[i]);
      function completeHandlerProps(eventProps:Event):void {
              trace("two: " + itemsArr[i]);
      }// end of fn for props
                    }//end of "for" loop of ads names
        }//end of fn for ads names
But i get the following output:

As you see, the "red text" is errors, Can you tell me the reason for it ?
And also, tracing "itemsArr[i]" in the second time, always give "null", also in the first time, it give the correct value, Why ?

the red text not appear after i posted the topic, but you can see the errors on the output
and, you've to create to text files, first called "ads.txt" and put in it "names=ad0;ad1"
second one called "ad0.txt" and put anything in it, and another called "ad1.txt" and put anything in it
all these files should be in the same dir of flash file

Are you sure String has a close method? I'm not sure your code compiles.
Exceptions have a getMessage method, which can be useful (and a printStackTrace method that can be even more useful.)

You could forgo the IF statements altogether by doing using NVL and TRIM this:

also you can simplify the GROUP BY by

Certain queries can only be executed when running your application, if your query appears syntactically correct, you can save your query without validation (see options below query source).
I can't for the life of me figure out where the invalid character is after "begin." All I can see is a blank character. Thanks for your help.

In the above you will notice that the values for name and id are repeated. This is not only illegal, but is very confusing for the kk() function as it does not know which value it is that you want.
My advice is to change the addrow() and deleterow() functions to allow for unique names and id's. Once you have done that, it is easy to allocate the values for the textbox.

Can you find the problem in this code?

I've searching some examples of the using of JTable on this forum.
So I've used a code found here.
But nothing happens, the JFrame doesn't appear on screen.
I'm sure my database "CLIENTES" exists inside the db folder. And also there's data inside "CLIENTES" table.
So, where is the problem then?
Thanks.

Regards
Arun

hi,
u failed to check relationship between tables and as well as mandatory fields need to be checked, i noticed following
from vbak as s1
join VBKD as k1
on s1vbeln = k1VBELN
join vbap as p1
on k1vbeln = p1vbeln and k1posnr = p1posnr
*join t178t as x1
*on p1kondm = x1kondm
join vbpa as r1
on p1vbeln = r1vbeln   <b>and p1posnt = r1posnr </b> join tpar as t1
on r1parvw = t1parvw
join ADRC as n1
on r1adrnr = n1addrnumber     <b> * No relation between these two tables/b]
join kna1 as c1
on r1land1 = c1land1 <b>and r1kunnr = c1kunnr</b> <i>'here u need to check mandatory fields also</i>
where k1vbeln = salesno and s1vbeln = salesno and p1~vbeln = salesno
and r1~vbeln = salesno.
anyway, in performance point of view, writeing code with this much joins is not acceptable.
comeback if you need any further help

Can anybody tell me the problem with this code when compiled in jdk1.4

Can anybody help me find out the error in this code.
Try to drag a file from your desktop and drop it on the first textpane on my GUI. Then try to drag another file. This time the dragdrop event handler throws a null pointer exception. This happened when I compiled the code with jdk1.4. With jdk1.3 it is working fine. Actually, I need jdk1.4 to get the systemicons for the files I drop on my desktop.

1. You have placed problem in wrong forum, or use different Windows operating system
2. Double check your resources, namely in Disk manager. What is free space on HDD?
