Hi

I tried make the Hello world kindlet by JDK 1.6.0_27, after signed .awz2 file and copied to Kindle, it now shows my app on HOME screen.

I tried to launch it but it just popup a box said: The Main Class for request title cannot be found. anybody could help me figure out the problem?

below are my source files and build steps:

1. Main.java

Code:
package test;


import com.amazon.kindle.kindlet.AbstractKindlet;
import com.amazon.kindle.kindlet.KindletContext;
import com.amazon.kindle.kindlet.ui.KTextArea;

public class Main extends AbstractKindlet {
        
        private KindletContext ctx;

        public void create(KindletContext context) {
                this.ctx = context;
        }

        public void start() {
                try {
                        ctx.getRootContainer().add(new KTextArea("Hello World,lol!"));
                } catch (Throwable t) {
                        t.printStackTrace();
                }
        }
}
2. Main.manifest

Code:
Manifest-Version: 1.0
Description: Test for Kindle
Main-Class: test.Main
Implementation-Title: Main
Implementation-Version: 0.0.1
Implementation-Vendor: Liuto
3. compiling ... I have put Kindlet-1.1.jar in my CLASSPATH environment

C:\xxx> javac Main.java

I got Main.class without any error.

4. Jar it...

Code:
  C:\xxx> jar cvfm Main.jar Main.manifest Main.class

added manifest
adding: Main.class(in = 857) (out= 500)(deflated 41%)
5. Sign it... I have put the key file in same directory

Code:
  
C:\xxx> signkindlet.bat
--------------------------------------------------------------
C:\xxx>rename Main.jar Main.azw2

C:\xxx>C:\"Program Files"\Java\jdk1.6.0_27\bin\jarsigner.exe -keystore developer.keystore -storepass password Main.azw2 dktest

C:\xxx>C:\"Program Files"\Java\jdk1.6.0_27\bin\jarsigner.exe -keystore developer.keystore -storepass password Main.azw2 ditest

C:\xxx>C:\"Program Files"\Java\jdk1.6.0_27\bin\jarsigner.exe -keystore developer.keystore -storepass password Main.azw2 dntest
6. copy Main.azw2 to Kindle

Thanks,
Nian
