2 Warnings when Project is built

[MobileDeveloper]

Hi

When I try bulding my Project it shows 2 warnings

Warning!: No entry points found

Warning!: No definition found for exported static routine: .main(String[])

What are those warnings about ?

Can some one please say how they can be avoided ?

Maybe you are trying to compile a MIDlet that is defined as CLDC-Application in the project options. Check the settings of your project.

Hi Ivanov

I am trying to compile an application

Here is the starting part

Can you please say what is the error ?


package com.blackberrydeveloper.FileName;
import net.rim.blackberry.api.phone.*;
public final class FileName extends AbstractPhoneListener {
static public void main(String[] args)
{
MyPhone.registerOnStartup();
}
static private void registerOnStartup()
{
FileName nm = new FileName();
Phone.addPhoneListener(nm);
}

you have to extend either the Application or UiApplication class...

Hi Ivanov

I have already made it extend from AbstractPhoneListener Class

How can I extend it further so that it wil extend from the UiApplication class too ?

Iam pretty weak in Java especially regarding extensions

Do you know how I can make it extend from both the Classes ?

Java cannot extend multiple classes.

I think what you need here is to create another class eg. MainApp and then do what you need in there. When the application is started, main will run.

public class MainApp extends Application {
  private static void main(String[] args) {
    ......
    MyPhone.registerOnStartup();
  }
}

Hi

Do you have any idea how I should write it ?

I am absoultely stuck and not sure how I should extend the PhoneListner class inside the main

Would you be able to show me the sample ?

Here is the main part of code ( that compiles with still those 2 errors ) that I am using

I have left outthe call listening and part as they are generic

package com.blackberrydeveloper.ImplCallDiverter;
import net.rim.blackberry.api.phone.*;
public final class ImplCallDiverter implements AbstractPhoneListener extends UiApplication {
static public void main(String[] args)
{
    
ImplCallDiverter.registerOnStartup();


ImplCallDiverter theApp = new ImplCallDiverter();
theApp.enterEventDispatcher();

}
static private void registerOnStartup()
{
    
ImplCallDiverter phn_hndl = new ImplCallDiverter();
Phone.addPhoneListener(phn_hndl);

}

I think your code should look something like this:

package com.blackberrydeveloper.ImplCallDiverter;

import net.rim.blackberry.api.phone.*;

public final class ImplCallDiverter extends UiApplication implements PhoneListener
{
    public static void main(String[] args)
    {
        ImplCallDiverter theApp = new ImplCallDiverter();
        theApp.enterEventDispatcher();
    }
    
    // Constructor
    ImplCallDiverter()    
    {
        Phone.addPhoneListener(this);
        
        // ...
    }    
}
