building HelloWorld and getting error...
Hey!I am new to J2ME and Wireless ToolKit.I have just started the sample codes.I compiled some codes and succeeded but some got the same errors.I am using WTK2.2. Can anybody help me?reply soon.
Here is the output shown by WTK when I tried to build HelloWorld code.
Project settings saved

Hi!
Thanks Hadhi and Superano for your quick reply.Anyways, here is the HelloWorld code.
package greeting;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class HelloWorld extends MIDlet implements CommandListener
{
private Display display;
private TextBox textbox;
private Command quitCommand;
public void startApp()
{
display=Display.getDisplay(this);
quitCommand=new Command("Quit",Command.SCREEN,1);
textbox=new TextBox("Hello World","My First Midlet",40,0);
textbox.addCommand(quitCommand);
textbox.setCommandListener(this);
display.setCurrent(textbox);
}
public void pauseApp()
{
}
public void destroyApp(boolean unconditional)
{
}
public void CommandAction(Command choice,Displayable displayable)
{
if(choice==quitCommand)
{
destroyApp(false);
notifyDestroyed();
}
}
}
and here is the RecordStore code..Both tends to produce the same kind of error.
import javax.microedition.rms.*;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import java.io.*;
public class RecordStoreEg extends MIDlet implements CommandListener
{
private Display display;
private TextBox textbox;
private Command quitCommand;
public void startApp()
{
display=Display.getDisplay(this);
quitCommand=new Command("Quit",Command.SCREEN,1);
textbox=new TextBox("Hello World","My First Midlet",40,0);
textbox.addCommand(quitCommand);
textbox.setCommandListener(this);
display.setCurrent(textBox);
}
public void pauseApp()
{
}
public void destroyApp(boolean unconditional)
{
}
public void CommandAction(Command choice,Displayable displayable)
{
if(choice==quitCommand)
{
destroyApp(false);
notifyDestroyed();
}
}
}
I need an immediate reply...

i am building the same code.
i have no problem in javac and preverify command
but when i;m trying to do the midp command there's error occured.
====================
D:\j2me\src\greeting>javac -d d:\j2me\tmp_classes -target 1.1 -bootclasspath d:\
j2me\midp2.0fcs\classes HelloWorld.java
D:\j2me\src\greeting>preverify -d d:\j2me\classes d:\j2me\tmp_classes
D:\j2me\src\greeting>midp -classpath d:\j2me\classes greeting.HelloWorld

=====================
i've been googling for sometimes and find out some similar problems.
one of the solutions offered is to change MIDP_HOME variable from "D:\j2me\midp2.0fcs;" into "D:\j2me\midp2.0fcs" (without semicolon).
i have tried this. but it's not working.
i have followed the installation guide from the complete reference J2ME book. (page 48-50)
i am using :
C:\j2sdk1.4.2_01
D:\j2me\j2me_cldc
D:\j2me\midp2.0fcs
any respons and solutions offered are welcomed.
