Hi Rahul. Posting your code could help others help you.

[rchadalawada]

I am using the below code to display background image.

currentForm.getStyle().setBgImage("/bg_image.png");

Merged the threads, as my current impression is that it is a single issue about accessing the images. First of all make sure they are really present in the package.
Honestly said I can not decode the call itself, with this "/xy.png" argument. I do not code for mobile Java, but whatever documentation and examples I see, they expect/pass an Image as argument to these methods, and use Resources.getImage("xy.png") or Image.createImage("/xy.png") for getting that.

hi ,

i have tried everything using resourse.getimage("uu"); also..the thing it works fine in default emulators using normal lwuit..but using lwuit for s40 it has some issue i cant add images to my commands..this issue is with only lwuit for s40...

Just an absurd idea, but have you tried the three parameter constructor, the one with that ID? Or with the set…Icon methods?
Another option to check: oneOfYourCommandInstances.getClass().getResourceAsStream("uu") is it null?

[rchadalawada]

yea i tried the 3 parameter constructor also.. and the method u told doesnt return a null..the thing is that only the icon of the last command added is displayed that to as a action command to the right of the screen and all other icons are not displayed.i tried everything working on it from past 2 days please help me out i am going out of my mind...

Can you replicate this behavior in other applications.

Since you have not got a solution yet, I think it could be worth creating a small application showing the issue and posting the complete code here, so it is easier for others to try the code and test other options.

Just a thought.

public void actionPerformed(ActionEvent arg0) {
int cmdId = arg0.getCommand().getId();
switch(cmdId){

private void sampleAction(){
this.centerLabel.setText("Command2 Acknowledged!");
}

private void exit() {

notifyDestroyed();
}
}

heres the sample code i am using

Ah, this is something was thinking about, just did not ask because of the lack of my experience:
- do you get all the commands even if they do not have icons next to them?
- because if not, it probably means that you get an exception somewhere in the try block, and the later lines are not executed.
I see those lines are commented now, but I assume we are actually talking about them.

hi wizard_hu_,

every command is executed because i see the command name of every command on my ui and its actions also works fine the only thing is i cant see the icon of that command .
