What is wrong with this code? please help

Hello,
Please pardon if you find my question too simple. I have the following
code
<form method=get action="page1.jsp">
<input type=hidden name=Id value="<%= rs.getInt("id")%>" >
<input type=hidden name=Title value="<%= rs.getString("title") %>" >
<input type=hidden name=Price value="<%= rs.getDouble("price")%>" >
<input type=submit name=operation value="Add">
</form>
i think they may be a problem here but i don't really know where .
please could someone help me?
Thank you.

What is wrong with this code? on(release) gotoAndPlay("2")'{'

Please could someone tell me what is wrong with this code - on(release)
gotoAndPlay("2")'{'
this is the error that comes up and i have tried changing it but it is not working
**Error** Scene=Scene 1, layer=Layer 2, frame=1:Line 2: '{' expected
     gotoAndPlay("2")'{'
Total ActionScript Errors: 1 Reported Errors: 1
Thanks

If you have a frame labelled "2" then it should be:
on (release) {
    this._parent.gotoAndPlay("2");
or other wise just the following to go to frame 2:
on (release) {
     this._parent.gotoAndPlay(2);
You just had a missing curly bracket...

I can't figure out what's wrong with this code

First i want this program to allow me to enter a number with the EasyReader class and depending on the number entered it will show that specific line of this peom:
One two buckle your shoe
Three four shut the door
Five six pick up sticks
Seven eight lay them straight
Nine ten this is the end.
The error message i got was an illegal start of expression. I can't figure out why it is giving me this error because i have if (n = 1) || (n = 2) statements. My code is:
public class PoemSeventeen
public static void main(String[] args)
EasyReader console = new EasyReader();
System.out.println("Enter a number for the poem (0 to quit): ");
int n = console.readInt();
if (n = 1) || (n = 2)
System.out.println("One, two, buckle your shoe");
else if (n = 3) || (n = 4)
System.out.println("Three, four, shut the door");
else if (n = 5) || (n = 6)
System.out.println("Five, six, pick up sticks");
else if (n = 7) || (n = 8)
System.out.println("Seven, eight, lay them straight");
else if (n = 9) || (n = 10)
System.out.println("Nine, ten, this is the end");
else if (n = 0)
System.out.println("You may exit now");
else
System.out.println("Put in a number between 0 and 10");
I messed around with a few other thing because i had some weird errors before but now i have narrowed it down to just this 1 error.

There are two file filters
class javax.swing.filechooser.FileFilter
interface java.io.FileFilter
In Swing you need to make a class which extends the first one and implements the second. Sometimes you may not need to implement the second, but it is more versitle to do so and requires no extra work.

hi,
but the upper limit is changing everytime you call the function recursively
so there should not be any problem(i suppose)
my intension is to get the unmatched elements of the two vectors
suggest me changes and thanks in advancce
ashok
The problems comes from the fact that you remove
elements for a Vector while iterating in a loop where
the upper limit as been set to the initial size of the
Vector.
You should use so while loops with flexible stop
conditions that would work when the size of the Vector
changes.
Finally: why don't you use Vector.equals() ?

Help!!! What's wrong with this code. JSP page can't retrieve properties.

I'v got a piece of code that was created to send some parameters to JSP page via POST method. But in server page I can't retrieve this parameters, please help me and try to find "main" bug in this code.
try {
URL url = new URL("http://localhost/index.jsp");
HttpURLConnection httpCon = (HttpURLConnection)url.openConnection();
httpCon.setRequestMethod( "POST" );
httpCon.setDoOutput( true );
String body = URLEncoder.encode("name=Oleg", "UTF-8");
httpCon.setRequestProperty( "Content-length", Integer.toString( outBody.length() ));
httpCon.setRequestProperty( "Content-type", "application/x-www-form-urlencoded" );
OutputStream os = httpCon.getOutputStream();
PrintWriter ow = new PrintWriter( os );
ow.print( body );
ow.flush();
ow.close();
} catch (....) {
}

Hi
You must not encode all the body just the values of the parameters.
You can do as following in order to send a post request with 2 parameters
String param1 = "Co & sons";
String param2 = "ltd.";
String encParam1 = URLEncoder.encode(param1,"UTF-8");
String encParam2 = URLEncoder.encode(param2,"UTF-8");
String body = "param1="+encParam1+"&param2="+encParam2;
OutputStream os = httpCon.getOutputStream();
PrintWriter ow = new PrintWriter( os );
ow.print( body );
ow.flush();
//read the response from the jsp
InputStream inS = httpCon.getInputStream();
byte[] buff = new byte[5000];
StringBuffer sbuff = new StringBuffer();
int nrBytes ;
while( (nrBytes = inS.read(buff, 0, 5000))!=-1) {
sbuff.append(new String(buff,0,nrBytes));
inS.close();
ow.close();
...This is the jsp page which gets the parameters
<%
     String param1 = request.getParameter("param1");
     param1 = new String(param1.getBytes(),"utf-8");
     String param2 = request.getParameter("param2");
     param2 = new String(param2.getBytes(),"utf-8");
%>I hope I helped you.

What's wrong with this code (AS3)?

I want to publish a live stream and, when a button is pressed, publish the same stream for vod. I haven't been able to get an answer as to whether I can do this...my code is below. Can someone please tell me if I can do this, or what may be wrong with my code?
The live stream and playback works fine; but the recording doesn't start. Also, I want other objects on the client, such as the current camera and audio information, and the aspect ratio being used. I havent' been able to get these to show up (i.e., the incomingLbl and outgoingLbl do not show up).
Thank you,

use event.currentTarget (and you don't need to repeatedly define the same function):
var c:int;
var buttonName:String;
for (c = 1;c < 5;c++) {
     buttonNum = "button"+c;
     this[buttonNum].addEventListener(MouseEvent.MOUSE_DOWN, pressStepButton);
function pressStepButton(event:MouseEvent) {          trace(event.currentTarget,event.currentTarget.name);     }

Crop Functio... what is wrong with this code???

Hi all,
I have created this method to crop my bufferedimage, but when i call it it does not seem to do anything. :(
Can anyone see what is wrong with it please?
Thank you for you help!
Claire
x
     public BufferedImage cropImage()
          mBufferedImageCrop = copy(mBufferedImage);
          Graphics grphc = mBufferedImageCrop.getGraphics();
          Rectangle desiredArea = new Rectangle(10,10,10,10);
          BufferedImage sub_bi = mBufferedImageCrop.getSubimage(desiredArea.x, desiredArea.y,
                                                                             desiredArea.width, desiredArea.height);
          grphc = mBufferedImageCrop.getGraphics();
          grphc.drawImage(sub_bi, desiredArea.x, desiredArea.y, this);
          repaint();
          return sub_bi;
     }I call this method using:
displayPanel.cropImage();
displayPanel.validate();
repaint();Thanx

I worked out the problem!

What's wrong with my code? Help

I'm attaching the code here in case it'd help in getting a faster response. This is supposed to be an exercise in turtle graphics. The idea is to use the program to draw shapes using a series of commands (I'm sure the experts here are familiar with it). It compiles and runs fine, however whenever certain commands are entered, after the move command, the program gives an exception "Array is out of bounds".
For instance, if I enter
1)2, 5, 1(step), 5, 1( step)
and the print result it also not working.
I'm a newbie to this, and I'm just trying to learn. Please help!

84)Can anyone help? I'm out of ideas and frustrated

What is wrong with this? pls help!

I have this as a listener for a JButton:
     public void actionPerformed(ActionEvent e){
          try{
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               String url = "jdbc:odbc:RezSystem";
               Connection con = DriverManager.getConnection(url, "user10", "");
               PreparedStatement stmt = con.prepareStatement("select cPassword from RezShopper where cShopperID = ?");
               stmt.setString(1, textSignInName.getText());
               ResultSet res = stmt.executeQuery();
               if(res.next()){
                    String tp = String.valueOf(passPassword.getPassword());
                    String dp = res.getString(1);
                    System.out.println("text field = " + tp);
                    System.out.println("database = " + dp);
                    if (dp.equals((String)dp)){
                         System.out.println("Password accepted");
                    else{
                         System.out.println("Invalid password");
               else{
                    System.out.println("Invalid sign in name");
          catch(Exception ex){
               System.out.println(ex);
     }this is used to compare the value in a password field and a value in a column in an sql data base with a char data type and should check if they are the same. The problem is that even if they are the same it still prints out "Invalid password". What went wrong???
thanks

dp.equals(dp) should give you true, but I guess you meant dp.equals(tp). To debug it, I would print the character values of both strings. You don't need to cast the String to a String before you call equals..
for (int x = 0; x < dp.length(); x++)
System.out.println("dp("+x+")="+(int)dp.charAt(x));
for (int x = 0; x < tp.length(); x++)
System.out.println("tp("+x+")="+(int)tp.charAt(x));I assume that getPassword returns a char array and not a byte array. If it returns a byte array, it is possible that the charset encoding gives you a different string than you expected.

What's wrong with this query--need help

Requirement: need to get the names of employees who were hired on tuesday this has to use to_char function
select ename
from emp
where to_char(hiredate,'day')='tuesday';
when i execute the query
o/p is no rows selected
please help.
thanks in advance.

when i execute the query
o/p is no rows selected Try:
WHERE TO_CHAR (hiredate, 'fmday') = 'tuesday'Without 'FM" in the 2nd argument, TO_CHAR pads the results to make it a consistent length. If your NLS_DATE_LANGUAGE=ENGLISH, that means it will always return a 9-character string, since the longest name in English ('Wednesday') has 9 letters. 'FM' (case-insernsitive) tells TO_CHAR not to add that kind of padding.

Connected to Internet or not connected? what is wrong with this code?

hi
here is a simple code to check whether Internet is connected to my machine or not----------
import java.net.*;
class CheckNet
     public static void main(String args[])
          while(true)
               check();
               try{
               Thread.sleep(1000);
               }catch(InterruptedException ie){System.out.println(ie);}
     static void check()
          try
                         String hostAddress ;
                         InetAddress localHost ;
                              localHost = InetAddress.getLocalHost();
                              hostAddress = localHost.getHostAddress();
                              if (hostAddress.equals( "127.0.0.1" ))
                              System.out.println("Not connected");
                              else
                              System.out.println("Connect to host: " + hostAddress);
                    catch(UnknownHostException ukhe){System.out.println(ukhe);}
this code tells the status of connection at first call of method check() in code, but can not update itself i.e if status of net conn is changed prog continues to output the same result.
CAN ANYBODY HELP ME TO REMOVE THE BUG / or suggest a better way?
regards

I've run into the same issue and found the following:
InetAddress caches successful and unsuccessful host name resolutions (See JavaDocs for InetAddress for more detail on this).
My guess is that InetAddress has cached the unsuccessful attempt and therefore when a network connection is established in your application loop, InetAddress "thinks" its still not connected.
The JavaDocs say something about setting a security property which can control the cache time, but I haven't been able to get InetAddress to recognize the property change. I'm probably not setting it in the right place.

Empty field Validation before Print, What's Wrong with THIS code??

I have been trying unsuccessfully to get this code to work.. I am stumped! I created a print button. Then added this script under "Form Calc" in the Click event of the button. But when clicked nothing happens. I have a radio button group that has different options but I only want to make the field NameofReferralSource required if the user checks Broker. The print button is on page 1. The field and radio button group are on page 7. I just can't figure out how to get this to work. I don't necessarily need to make the fields required since then I would have to add script remove the red border and add a message telling user where the field is otherwise they will have to search through 6 pages to find it. (maybe a better solution?) I just want a simple code that fires when the user hits the Print, Save, or Submit button to check if Broker name is empty and if it is, prompt them to fill in. Help!
if ((topmostSubform.Page7.NameofReferralSource.rawValue == null) & (topmostSubform.Page7.Howdidyouhear.0.rawValue == "Broker")) then
xfa.host.messageBox("You must enter the the Name of the Broker under Referral Name on Page 7 to be able to print this form")
else
Print_Form.execEvent("click")
endif
Brenda

Ok, well my reference to the fields were incorrect. Here is the new code:
if (Page7.NameofReferralSource.rawValue == null){
xfa.host.messageBox("You must enter the the Name of your Referral on the bottom of Page 7 to be able to print this form");
}else{
Print_Form.execEvent("click");
xfa.host.print(1, "0", (xfa.host.numPages -1).toString(), 0, 0, 0, 0, 0);
The first part that checks for an empty field and displays a message works however the print dialog still pops up after the user clicks ok to the error message. Any ideas?

What's wrong with this code. Any Help please?

Hello
I'm a newbie to java programming.I got this sample code from an online book that I use in learning java and I'm trying to run the code on eclipse but I got this error message
"Fatal exception occurred. Programm will exit."
This is the code:
public class MostDivisors {
     public static void main(String[] args) {
          int N;
          int maxDivisors;
          int numWithMax;
          maxDivisors = 1;
          numWithMax = 1;
          for(N = 2 ; N <= 10000 ; N++){
               int D;
               int divisorCount;
               divisorCount = 0;
               for(D=0; D <= N; D++){
                    if (N % D == 0)
                         divisorCount++;
               if (divisorCount > maxDivisors){
                    maxDivisors = divisorCount;
                    numWithMax = N;
          System.out.println("Among intergers between 1 and 10000,");
          System.out.println("The maximum number of divisors is "+maxDivisors);
          System.out.println("A number with " + maxDivisors + " divisors is ");
Any Help will be appreciated. Thank you all for helping me out understand the problem here

Thank you all participating to help this out.
This is the code and the detailed error message:
public class MostDivisors {
     public static void main(String[] args) {

          int maxDivisors;

          maxDivisors = 1;
          numWithMax = 1;
          for(N = 2 ; N <= 10000 ; N++){
               int D;
               int divisorCount;
               divisorCount = 0;

          System.out.println("The maximum number of divisors is "+maxDivisors);
          System.out.println("A number with " + maxDivisors + " divisors is ");
ERROR MESSAGE starts HERE:
java.lang.ArithmeticException: / by zero
     at MostDivisors.main(MostDivisors.java:30)
Exception in thread "main"
I do not think this is related to the JVM because other programs will compile and run successfully.
Any Help will be appreciated. Thanks
