FB4 doesn't tell me what's wrong with my code. Not even letting me trace().

Attached is my code that run well but the problem is, I know there is something wrong with my code since the dropdown list isn't populated unlike the textarea. Doesn't even put anything on the output panel when i do trace()-ing.

@jdesko:
i tried both with or w/o the nightly builds, still i can't see anything on the output panel using trace and the above code doesn't trigger the Error Panel why the dropdown list isn't populated..
@Jason: thanks. the prob was with my e4x expression but with the console output thingy, now i run in debug mode but got the error:
C:\Windows\System32\Macromed\Flash\NPSWF32.dll
Flash Builder cannot locate the required debugger version of Adobe Flash Player. You might need to install the debugger version of the Flash Player or reinstall Flash Builder.
Do you want to try to debug with the current version?
I thought FB4 has this already in the package. I'm wondering why it asks for like this.

Please tell me what is wrong with my code.

Hi there,
I have developed a simple class alpPhoto.java in which I can find out the width height of a image using ImageIcon. Everything works fine when I deploy myApp.ear file on my OC4J - NT version. But when I deploy myApp.ear file on my OC4J - Unix version, the jsp that I call alpPhoto got hung until timed out. Here is the code of alpPhoto:
import java.io.*;
import java.util.* ;
import javax.swing.*;
import java.net.*;
public class alpPhoto {
private int ImgWidth ;
public void setImgWidth(int width )
this.ImgWidth = width ;
public int getImgWidth()
return this.ImgWidth ;
private int ImgHeight ;
public void setImgHeight(int height)
this.ImgHeight = height ;
public int getImgHeight()
return this.ImgHeight;
private String ImgURL ;
public void setImgURL(String strURL){
this.ImgURL = strURL ;
public String getImgURL()
return this.ImgURL ;
public alpPhoto(String imgPath) throws Exception
if( imgPath == null || imgPath == ""){
throw new Exception("The physical path to the photo is empty.") ;
}else{
System.out.println( imgPath);
File myFile = new File(imgPath) ;
if(myFile.exists()){
URL myURL = myFile.toURL() ;
setImgURL( myURL.toString() );
ImageIcon image = new ImageIcon(myURL);
setImgWidth( image.getIconWidth() );
setImgHeight( image.getIconHeight()) ;
}else{
throw new Exception(imgPath + " does not exist.\n\n") ;
Here is how I call this class in my jsp file:
<%
alpPhoto curPhoto = new alpPhoto(imgPath) ;
int width = curPhoto.getImgWidth();
int height = curPhoto.getImgHeight();
%>
where the "imgPath" is the parameter passed from other jsp file.
I wonder if there is bug or obviously what is the main difference between the OC4J - NT version and the OC4J - Unix version.
Thanks in advance.
Henry

Not sure if this will help, but take a look at the MediaTracker class. The MediaTracker will wait until an image is completely loaded before continuing. This will ensure that you width/height values are always non-zero.

Can someone tell me what's wrong with this code....

Everything is ok if i take the for loop out, but for some reason everything just gets screwed up if I have that for loop in there. And these are the error messages I'm getting.

Hey I'm sorry but this is only my second week doing

give me an example??
Bad Version (like yours but simplified)

    for(int i=0;i<20;i++){
      String whatIsUp(){
         return "Doc";
      System.out.println(?);// I am not even sure how to write this voodoo part
}Good Version
public class Sample{
public static void main(String args[]){
    for(int i=0;i<20;i++){
      String aString = whatIsUp();
      System.out.println(aString);
String whatIsUp(){
    return "Doc";
}

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.

I can't install Bundle for MS Office into my Macbook Pro. I've bought it but once I start to install it says "An error has occurred" but it doesn't tell me what's wrong.

I've bought the Bundle however, it won't fully install. It keeps on saying "error has occurred" but it doesn't tell me what's wrong. I have a new harddrive in my computer so it's not like I don't have enough space.

The newest version I think? Idk it's the only version on the APP store. I also have the newest version of OSX that I just installed. I thought maybe because I hadn't installed the newest OSX version that it wouldn't work so I installed it and still nothing.

Youd don't have a class file. Compile it first then run it. If your compiler isnt making the .class file tell me and ill give you a link to a realy good java compiler.

JScrollPane, what is wrong with my code?

Hi, I appreciated if you helped me(perhaps by trying it out yourself?)
I wanted my JScrollPane to display what is drawn on my canvas (which may be large)by scrolling, but it says it doesn't need any vertical and horizontal scroll bars. Here is the code that has this effect
import javax.swing.*;
import java.awt.*;
public class WhatsWrong extends JApplet{
public void init(){
Container appletCont = getContentPane();
appletCont.setLayout(new BorderLayout());
JPanel p = new JPanel();
p.setLayout(new BorderLayout());
p.add(new LargeCanvas(),BorderLayout.CENTER);
int ver = ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED;
int hor = ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED;
JScrollPane jsp = new JScrollPane(p,ver,hor);
appletCont.add(jsp,BorderLayout.CENTER);
class LargeCanvas extends Canvas{
public LargeCanvas(){
super();
setBackground(Color.white);
public void paint(Graphics g){
g.drawRect(50,50,700,700);
and the html code:
<html>
<body>
<applet code="WhatsWrong" width = 300 height = 250>
</applet>
</body>
</html>
What shall I do?
Thanks in advance.

What is wrong with your code is that your class, LargeCanvas must implement the Scrollable interface in order to be scrolled by a JScrollPane.
A comment regarding your use of Canvas and Swing components: The Java Tutorial recommends that you extend JPanel to do custom painting. Canvas is what they call a "heavyweight" component and they recommend not to mix lightweight (Swing) components and heavyweight components.
There is a lot more information on custom painting on the Java Tutorial in the Lesson "Creating a GUI with Swing.

public boolean isCellEditable(int row, int col) {
return false;

}

Inside your table model you use a Vector to hold your data. Create a method on your table model
public void removeRow(int rowIndex)
    data.remove(rowIndex); // Remove the row from the vector
    fireTableRowDeleted(rowIndex, rowIndex); // Inform the table that the rwo has gone
[/data]
In the class that from which you wish to call the above you will need to add a reference to your table model.

What's wrong with these code?

Hi, i made the below snippet of code for retriving data from a table in database. but it doesnt work property when i run the program. Could anyone tell me what's wrong with it? Thanx in advance.
//rs is object of type ResultSet
//url is one of the column names in a table
<% if(rs.getString("url")!= null){%>
   <tr>
      <td>URL </td>
      <td>= { <%= rs.getString("url") %> },</td>
</tr>
<%}%>

Without seeing the error message, one can only guess. Some JDBC drivers do not allow you to get a column more than once, so that may be your problem. Store the result of rs.getString("url") in a String variable in the first line, and use that variable in the table cell.

FB4 doesn't tell me what's wrong with my code. Not even letting me trace().
