EMDK for Java - symbol.Audio



currently I am trying to build a little commandline tool which is able to trigger a signal on the device (MT2070).

I downloaded the EMDK for Java and found the JAR-Files und samples.


I now have the following code: 


// TriggerBeep.java

import symbol.Audio


public class TriggerBeep


public static void main( String[] args )


  int iVersion = 1;

  System.out.println( "TriggerBeep commandline tool" );

  iVersion = symbol.Audio.getVersion();




compiled with:  javac -cp symbolclasses.jar TriggerBeep.java

executed with:  java TriggerBeep


Exception in thread "main" java.lang.NoClassDefFoundError: symbol/Audio

        at TriggerBeep.main(TriggerBeep.java:9)

Caused by: java.lang.ClassNotFoundException: symbol.Audio

        at java.net.URLClassLoader.findClass(Unknown Source)

        at java.lang.ClassLoader.loadClass(Unknown Source)

        at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)

        at java.lang.ClassLoader.loadClass(Unknown Source)

        ... 1 more


Is there more to add to the option 'cp' to get this code run?

What to change to solve this problem?


Thanks in advance!
