Hii

I've created a simple application that displays an advertisement. I used this article. I followed all steps but I get NoClassDefFound error on the BlackBerry 9900 simulator.i've downloaded the jar files from this url

For this I have used preverify.exe to check jar file to be compatible with net_rim_api.jar:

on my CMD:

preverify -classpath "D:\Eclipse\plugins\net.rim.ejde.componentpack7.1.0_7.1.0.10\com ponents\lib\net_rim_api" "net_rim_bbapi_adv_app.jar" "D:\Eclipse\plugins\net.rim.ejde.componentpack7.1.0_7.1.0.10\components\bin\output"
i am getting like this,what should i do?

Error preverifying class net.rimlib.blackberry.api.advertising.app.a
java/lang/NoClassDefFoundError: java/lang/Thread

Here my Code:

import net.rim.device.api.ui.UiApplication;
import net.rim.device.api.ui.container.MainScreen;
import net.rimlib.blackberry.api.advertising.app.Banner;

public class AdDemo extends UiApplication{
public static void main(String[] args)
{
AdDemo theApp = new AdDemo();
theApp.enterEventDispatcher();
}

public AdDemo()
{
pushScreen(new AdDemoScreen());
}

}

class AdDemoScreen extends MainScreen{

public AdDemoScreen()
{
Banner bannerAd = new Banner(16741, null);
bannerAd.setMMASize(Banner.MMA_SIZE_EXTRA_LARGE);
add(bannerAd);
}

}

How can I overcome this issue?

Thank you..

can you able to execute this app from your side?

You do not need to preverify the jar.  All you need to do is include the jar in your build path and make sure you export the jar.  Here are the instructions you need:

Hi Peter

             i have followed the steps given in the documentation clearly,but still i am facing NoclassDeffound Error...what can i do?

[peter_strange]

What class is having the error?  In other words, what class is not found?

Did you Export the jar?  In other words did you tick the check box on the Order & Export tab of the Build Path?

[pavankumarragi]

it is not showing any particulatr class name,when i execute the app,on the screen i am getting noclassdeffound error,i export the jar and i checked it correctly

[peter_strange]

When you debug this do you not see a class name?

Whereabouts in your code is this problem occurring.  We need to confirm that it is the add code that is causing the problem.

Do you see this problem on the SImualtor?

ya,i have used try catch blocks like this to catch an exception ,but i am not able to print the statement

class AdDemoScreen extends MainScreen{

try{

public AdDemoScreen()
{
Banner bannerAd = new Banner(16741, null);
bannerAd.setMMASize(Banner.MMA_SIZE_EXTRA_LARGE);
add(bannerAd);

}

catch(Exception e){

S.o.p("Error"+e.getMessage());

}

}

can you execute this demo app from your side and let me know   are you facing the issue or not?
