LWUIT compile-time error

[barafyzil]

i am a newbie to LWUIT so probably thats why i am having this problem.This is my code


import com.sun.lwuit.Button;
import com.sun.lwuit.Display;
import com.sun.lwuit.Form;
import com.sun.lwuit.Label;
import com.sun.lwuit.events.ActionEvent;
import com.sun.lwuit.events.ActionListener;
import com.sun.lwuit.layouts.BorderLayout;
import com.sun.lwuit.plaf.UIManager;
import com.sun.lwuit.util.Resources;
import java.io.IOException;


public class Ruwwa extends javax.microedition.midlet.MIDlet implements ActionListener{

Form f;
Button mybutton;

public void startApp() {

f = new Form("Mairuwa Portal");
mybutton=new Button("Exit");

f.setLayout(new BorderLayout());
f.addComponent(BorderLayout.CENTER, new Label("Welcome to the Mairuwa Portal"));

mybutton.addActionListener(this);
f.addComponent(BorderLayout.SOUTH,mybutton);

Display.init(this);

try {

Resources r = Resources.open("/working.res");
UIManager.getInstance().setThemeProps(r.getTheme("Mairuwa Theme"));

} catch (IOException ioe) {
ioe.printStackTrace();
}
f.show();
}

public void pauseApp() {}

public void destroyApp(boolean unconditional) {}

public void actionPerformed(ActionEvent ae) {
notifyDestroyed();
}

}


I compiled this using the NOKIA SDK 1.0 emulator and added the NOKIA_IO.JAR, LWUIT_MIDP.JAR and the MIDP_IO.JAR to the resources folder.I also added my theme "working.res" to the src folder of the package.
In my application descriptor, i have "Ruwwa" as Midlet name and "Ruwwa" as my class name

I got the following error when did the build:

Created dir: C:\Users\HAFIZ\Documents\NetBeansProjects\Mairuwa\build\preverifysrc

i got the following error when i did the clean and build:

Error preverifying class com.sun.lwuit.impl.midp.CanvasImplementation

I also got the following error in the emulator when i ran it:

class Not Found java/lang/classNotFoundException Ruwwa

The first thing you need to do is initialize the display. You need to place this line:

Display.init(this);

right after this line:

public void startApp() {

Only the LWUIT_MIDP.jar is needed in your case.
Also if you are using eclipse, make sure that you right click on your project's LWUIT_MIDP.jar and select Add to Build Path. After you have added it to the build path, right click again and select Build Path>Configure Build Path>Order and Export> Select the LWUIT_MIDP.jar checkbox.

i use netbeans and i just replaced the line.
i still get the Error preverifying class com.sun.lwuit.impl.midp.CanvasImplementation
VERIFIER ERROR com/sun/lwuit/impl/midp/GameCanvasImplementation.paintVideo(Lcom/sun/lwuit/Component;ZLjava/lang/Object;Ljava/lang/Object;Ljava/lang/ObjectV:

C:\Users\HAFIZ\Documents\NetBeansProjects\Mairuwa\nbproject\build-impl.xml:483: Preverification failed with error code 1.
BUILD FAILED (total time: 11 seconds)

Is there a way one can set build path in netbeans.

My aim is to make sure the label and button show on the theme("Mairuwa Theme") which i had created with the LWUIT resource editor (mairuwa.res)

Hello barafyzil,

Cannot find class javax/microedition/media/control/VideoControl

Have you selected (check-marked from Properties -> Optional Packages) Mobile Media API from the IDE for the Nokia SDK?
