Loading image in Java J2ME
java, java-me, lcdui, midp
Solution
As msell said - You can't access images from Your computer. Make sure that You have included the given image in midlet jar file. If You try to access it using '/picture.png', then it should be located a the root directory in jar.
Problem
I have a problem with loading image with java 2ME. I have a image file "picture.png" in location drive "C:". After that I wrote my like this to show image from this location. ``` import javax.microedition.midlet.*; import javax.microedition.lcdui.*; import java.io.*; public class ImageMidlet extends MIDlet implements CommandListener{ private Display display; private Command exitCommand; private Command backCommand; private Command okCommand; private Form form; private ImageItem imageItem; private Image image; public ImageMidlet(){ display = Display.getDisplay(this); form=new Form(""); exitCommand = new Command("Exit", Command.EXIT, 1); backCommand = new Command("Back", Command.BACK, 2); okCommand = new Command("OK", Command.OK, 3); try { image=Image.createImage("/picture.png"); imageItem=new ImageItem(null,image,ImageItem.LAYOUT_NEWLINE_BEFORE,""); } catch(IOException ex){ } form.append(imageItem); form.addCommand(okCommand); form.addCommand(exitCommand); form.addCommand(backCommand); form.setCommandListener(this); display.setCurrent(form); } public void commandAction(Command c,Displayable d){ } public void startApp() { } public void pauseApp() { } public void destroyApp(boolean unconditional) { } } ``` It shows me this error: ``` Unable to create MIDlet Test.ImageMidlet java.lang.NullPointerException at javax.microedition.lcdui.Form.append(Form.java:638) at Test.ImageMidlet.<init>(ImageMidlet.java:39) at java.lang.Class.runCustomCode(+0) at com.sun.midp.midlet.MIDletState.createMIDlet(+34) at com.sun.midp.midlet.Selector.run(Selector.java:151) ``` I am starting learn to develop, so please guide to do this.
