J2ME IMAGE GHOSSTTTEEE

[nasir031]

Hi formers how are you?
I'm here again with very simple and stupid problem, That I'm in trouble in getting the image from res folder
Hoping good and brisk response from you guys
a bundle of thankx for all of you......
here is my source code I'm getting with....

THIS IS THE MAIN MIDlet

package imageeo;

import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

/**
* @author 031-bscs-08
*/
public class ImageMidlet extends MIDlet implements CommandListener{

private Image image = null;
private ImageClass canvasClass;

public ImageMidlet()
{
}


public void startApp()
{
canvasClass = new ImageClass();
canvasClass.addCommand(new Command("Exit", Command.EXIT, 0));
Display.getDisplay(this).setCurrent(canvasClass);
}

public void pauseApp() {}

public void destroyApp(boolean unconditional) { }

public void commandAction(Command c, Displayable d)
{
if(c.getCommandType() == Command.EXIT)
{
destroyApp(true);
notifyDestroyed();
}
}
}





AND HERE IS THE CANVAS CLASS



package imageeo;

import java.io.IOException;
import javax.microedition.lcdui.*;


/**
*
* @author 031-bscs-08
*/
public class ImageClass extends Canvas implements Runnable {


private Image image = null;

public ImageClass()
{
try {

// I think the lurks are here that are pushing my application down
this.image = Image.createImage("/res/Delete-icon.png");
new Thread(this).start();

} catch (IOException ex) {
ex.printStackTrace();
}
}


public void run()
{
while(true)
{
repaint();

synchronized(this)
{
try {
wait(50);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
}
}
}

protected void paint(Graphics g)
{
g.setColor(0xffffff);
g.fillRect(0, 0, getWidth(), getHeight());

if(image != null){
g.drawImage(image, getWidth() / 2, getHeight() / 2, Graphics.HCENTER
| Graphics.VCENTER);
} else {
g.setColor(0x000000);
g.drawString("No image available", getWidth() / 2, getHeight() / 2,
Graphics.HCENTER | Graphics.BASELINE);
}
}

}

So what are you getting ? An exception or simply the "No Image AVailable" message ?
Have you checked that thje filename is exactly like how you call it in the createImage method ? If i'm not mistaken it's case-sensitive so capital letters will make a difference...

Even the capital letter in the file extention may cause serious problem ... please check that once properly ..

[nasir031]

Yes your observation is exactally right I'm ending with "No Image AVailable" message. I gone through all the three times even Icopied the file name by editing its name and I'm sure about fileName and its case sensitivity even again I'm getting the same message..

Okay Tiger there would'nt be any private message from now onward
AND THANKS FOR REPLYING a lot of thanks.....

[nasir031]

Yes I've checked that three times even then, the message is same... Thankx bro

[Tiger79]

ok,
start by extending this part :
catch (IOException ex) {
ex.printStackTrace();
}

to something like
catch (IOException ex) {
System.err.println("Something wrong whilst creating Image : " + ex.toString()); //on emulator or if you are on device write it to a canvas or on a Alert
}

Simply don't use printStacktrace, it's of no use in j2me... try to catch the exceptions and write them somewhere you can read them !

[nasir031]

okay.. I'll do it and inform you soon.

doing in this way I'm getting this message "java.io.IOException"

[ektasrv]

doing in this way I'm getting this message "java.io.IOException"

Instead of this.image = Image.createImage("/res/Delete-icon.png"); line

try this.image = Image.createImage("/Delete-icon.png");

If it still fails:

After packaging it in the JAR, rename it from .jar to .zip and view it with winzip -- and check if contains "Delete-icon.png" file - compare its character case and path with in the jar with one in code... it looks to be some mismatch because of which this is giving - IOException.

Ekta, by doing "this.image = Image.createImage("/Delete-icon.png");" I've done it..Thankx
