How to load an image in my application

[golam.kaosar]

Dear all,
I know how to program in java. but dont have much idea about J2ME. i want a quick start thats why before going through detail, i want to develop a small application which would load an image (jpg or png) on the screen. i have been trying several times and looked at several forum posts here, but unfortunately i could not b succeed yet. would you please help me providing a small piece of code and step by step instructions!!!! please please please!!!
u can send email to me too (golam.kaosar@gmail.com)

Hi golam.kaosar,

check the javax.microedition.lcdui.Image class.
this is javadoc for it....

http://www.j2medev.com/api/midp/java...use/Image.html

this is the way you put an image into your midlet

Image b;
b.createImage("image.png");

dear,
thanks a lot for quick reply. i already saw these classes. but i tried in several ways and did not get success. now i m confused about the whole process. therefore an example program (code) would be the best remedy for this problem. if u have such example, please let me know.
thanks again.

copy paste your part of the code so that i can make out the mistake that your making. try to do it yourself rather than getting the readymade code...
You will learn better.

here is the code:
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
import java.io.*;
public class ImageTest extends Canvas implements Runnable{
private Image image;
private int x;
private int y;
private TiledLayer layer;
public ImageTest(String imageName)
throws ApplicationException {
try{
image=Image.createImage("/image1.png");
layer=new TiledLayer(7,7,image,20,20);
x=(getWidth()-layer.getHeight())/2;
y=(getHeight()-layer.getWidth())/2;
layer.setPosition(x,y);
}catch (IOException e){
throw new Exception("Unable to create Image");
}
}
public void paint(Graphics g){
layer.paint(g);
}
public void run(){
int n=0;
while(n<=21){
for(int i=0;i<7;i++){
for(int j=0;j<7;j++){
layer.setCell(i,j,(i+1)+n+(j*28));
}
}
repaint();
try{
Thread.sleep(100);
}catch(InterruptedException ie){}
n++;
}
}
}

here the constructor has an argument. i dont know when and how the argument should be sent. also i dont know where the image file should be located. if i run this program following error occurs:
Project "ImageTest" loaded
Project settings saved
Building "ImageTest"
C:\java\WTK\apps\ImageTest\src\ImageTest.java:10: cannot find symbol
symbol : class ApplicationException
location: class ImageTest
throws ApplicationException {
^
1 error
com.sun.kvem.ktools.ExecutionException
Build failed

i am using java wireless toolkit
i really appreciate and thank you for your kind and prompt reply.

your error isnt related to loading an image nor even to j2me
if u know java then it should be easy for u
it says it cant find the class ApplicationException
u declare the constructor to throw "ApplicationException" which is not a class or not in the src folder or the class-path
i think u ment "throws Exception"
since later on u do throw an Exception and nothing else


p.s
STOP SPAMMING your problem on all open threads
thread jacking is not nice or will help u
open one thread and wait for assistance

can u please give me a piece of code which would load an image file as the background of the application?
thanks

[pvumesh]

make sure all the images are in the res folder of your toolkit.

[golam.kaosar]

yes the image is there. i tried with the full path name too. i appreciate ur help. can i get your email address so that we could have more prompt communication.
thanks a lot
