Cant access another public class in the same Package. illegalAccessException

[tarang127]

Hi,
I am using Eclipse IDE, Ant and J2ME Polish to create an application. I have made two public classes in the same package. But, I am getting an illegalAccessException when I am trying to create an object of one class in another.

The code I have written is :
Class #1

package LocationFinder;

import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Form;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.List;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Displayable;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
import java.util.Timer;
import java.util.TimerTask;

class giveList extends TimerTask
{
public Display display;
public List firstList;

public giveList(Display display,List firstList)
{
this.display=display;
this.firstList=firstList;
}
public void run()
{
this.display.setCurrent(firstList);
}
}
public class firstScreen extends MIDlet implements CommandListener{

public Command quitCmd = new Command( "Quit", Command.EXIT, 0 );
public Command start=new Command("OK",Command.OK,0);
public Display display;
public Form firstScreen=new Form("New Form");
public Timer timer;
giveList menuScreen;
String options[]={"My Location","Messenger","Important Sites Here","Resources Here","Geographical Info"};
int selection;

List firstList= new List("Location Finder",List.IMPLICIT,options,null);

public firstScreen()
{
super();
//#style heading
this.firstScreen.append("Welcome");
this.firstScreen.addCommand(quitCmd);
this.firstScreen.addCommand(start);
this.firstList.addCommand(quitCmd);
firstScreen.setCommandListener(this);
firstList.setCommandListener(this);
}
protected void startApp() throws MIDletStateChangeException{
this.display = Display.getDisplay( this );
this.display.setCurrent( firstScreen );
timer=new Timer();
menuScreen=new giveList(display,firstList);
timer.schedule(menuScreen,1000);
}

public void commandAction(Command cmd, Displayable screen) {
if(cmd==quitCmd)
{
this.notifyDestroyed();
}
else if(cmd==start)
{
menuScreen.run();
}
else if(cmd==List.SELECT_COMMAND)
{
selection=firstList.getSelectedIndex();
getLocation locate=new getLocation(firstList,selection);
try
{
locate.startApp();
}
catch(Exception e)
{
//Do nothing
}
}
}

protected void pauseApp(){
}

protected void destroyApp(boolean unconditional) throws MIDletStateChangeException{
}

}

Class #2
package LocationFinder;

import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.List;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

public class getLocation extends MIDlet {

Display display;
List firstList;
int selection;

public getLocation(List firstList,int selection) {
super();
this.selection=selection;
this.firstList=firstList;
}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {


}

protected void pauseApp() {


}

public void startApp() throws MIDletStateChangeException {
this.display = Display.getDisplay( this );
this.display.setCurrent(firstList);
//#style heading
firstList.append("Selection is "+selection, null);

}

}

and my build file is :

Please help me out..I am stuck on the same problem since yesterday and I am not able to move ahead at all..Thanks..

Both classes are MIDlets. Only the Application Manager should create MIDlets; you should not instantiate them yourself. A MIDlet is the application itself; it doesn't represent a "screen". You must have only one subclass of MIDlet. "Screens" are those classes that extend javax.microedition.lcdui.Displayable.

Cheers,
Graham.

whats the need of instantiate another midlet in first midlet. Cant do like u done. Cant instantiate another midlet in other midlet in same package too.

[raj_J2ME]

Hi,
this is the reason for the error you are getting.

getLocation locate=new getLocation(firstList,selection);

As Grahm suggested,you can only have 1 midlet(multiple you can have in case of midlet suite).And just do whatever you want to do in the midlet constructor/startApp and then just forget...midlet will be called by the application manager and hence you need not to write the quoted line.

[prakash.raman]

Unless u want Multiple Midlet, means a midlet suite, u are a doing a very wrong way of j2me coding.

as a tip : it may be usefull NOT to quote a whole lot of code just to place half a sentence at the end of it
it might make the difference between a readable and a unreadable forum
