Hello
I am sorry, I make a mistake on some informations:
On real device B Midlet runs ok.
And when I take B.jar, and I put it on predefjava/predefcollections
directory of my emulator, B.jar runs well without exceptions.
Sorry about this mistake.
But, when I run directly from eclipse, I have always the same problem.
When I run from eclipse, it create a new directory
c:\windows\temp\ueiemulatorXXXX witch contains 3 files :
- classB.jar,
- classB.jad
- META-INF\MANIFEST.MF
When I unjar classB.jar, I dont see any trace of classA.
I see in console window this information :
UEIInvocationParameters: About to call
FileUtils.createFakeJadAndJar(classname=classBclasspath=C:\Java\B\verified\l
ibs\A.jar;C:\Java\B\verified\classes)
The file C:\Java\B\verified\libs\A.jar exists, no problem
About what you said export the external jar (in your build path->order and
export) and add it to the build path, I dont understand well the
difference.
What I made is :
Project / Properties / Java Build Path / Libraries / Add external jars
File : A/deployed/A.jar
Order and Export / Check the checkbox for A.jar
Thanks for advance for your help
Jean-Pierre

Objet : Re: [Eclipseme-users] Problem adding external jars to my application
I'm not that much of a configuration guy but I'm using a external jars (kxml
for exmaple) in my applications, one thing
that gives that NoClassFound error is when you forget to export the external
jar (in your build path->order and export) mark it so
that it gets deployed to the phone,
the one other thing is that after you've added the jar to your project you
have to add it to the build path, but I guess that's obvious.
hope this helps a bit,

Hello
I have the same problem on the emulator and the real phone.
The "not found" class is the class of the external jar.
I have the same problem (exception when running NoClassDefFoundError) when I
add the external project in the Project tab.
The steps to reproduce my problem:
File / New / Other / J2ME Midlet Suite
Project Name : "A"
Finish
File / New / Class
Package : "pkA"
Name : "classA"
Finish.
Here the code of the classA :
package pkA;
public class classA {
public static String GetInfoA()
{
return "GetInfoA";
}
}
Right click on project A in package explorer / J2ME / Create Package
File / New / Other / J2ME Midlet Suite
Project Name : "B"
Finish
File / New / Other / J2ME Midlet
Package : ""
Name : "classB"
Finish.
Project / Propreties / Java Build Path / Libraries / Add external jars
File : A/deployed/A.jar
Order and Export / Check the checkbox for A.jar
Here interesting code of ClassB:
public void ShowMessage(String aTitre, String aAlertText,
AlertType aAlertType)
{
// Création de la boite de dialogue « Alert »
Alert myAlert = new Alert(aTitre, aAlertText, null, aAlertType);
// Affichage de la boite de dialogue
Display.getDisplay(this).setCurrent(myAlert);
}
protected void startApp() throws MIDletStateChangeException {
String s = 'A'+classA.GetInfoA();
ShowMessage(s,s,AlertType.INFO);
}
Right click on project B in package explorer / J2ME / Create Package
Right click on project B in package explorer / Run as / Run
Right click on Wireless Toolkit Emulator / New
Name : "ConfigB"
Midlet : "classB"
Apply / Run
And now I have the exception :
Uncaught exception java/lang/NoClassDefFoundError: pkA/classA
Someone could tell me what I forget or I am doing wrong ?
For information, I have :
Eclipse : 3.2.2
EclipseME : 1.6.8
Sdk : S40_SDK_3rd_Edition_Feature_Pack_1.
When I unjar B.jar, I have the following files :
- pkA/classA.class
- classB.class
- META-INF/MANIFEST.MF
Thanks for advance.

Hello,
i do not think that the JAR must be named in the Manifest. Eclipse just
adds the files contained in the external JAR to the newly deployed JAR.
Where are you running your Midlet? On the emulator or on a real phone?
Maybe you should use try{} catch(Error err) in your startApp()-Method to
trace the Error and find out, which class was not found.
Did you try not to include the external JAR but the whole Project? In
the Projekt-Properties you can add that with the Projects tab. Then you
should receive a error if one class is missing.
Regards,
Markus
