    EMDK for Java - symbol.Audio

    Ralf Weber



      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!
