Android GCM - Class not found exception

I'm trying to use GCM with appengine, as shown in google's tutorial. On the server side, when I'm trying to do:

    Sender sender = new Sender(API_KEY);
com.google.android.gcm.server.Message message = new com.google.android.gcm.server.Message.Builder().addData("message",m).build();
for (String regId : u.getDeviceIds()) {
    try {
        Result result = sender.send(message,regId, 3);
        System.out.println("Message to " + u.getName() + " : " + result);
    } catch (IOException e) {

    }
}

I'm getting:

    org.restlet.resource.UniformResource doCatch: Exception or error caught in resource
java.lang.NoClassDefFoundError: org/json/simple/parser/ParseException
    at il.ac.technion.ssdl.hitch.model.GCMServices.sendMessage(GCMServices.java:24)

Line 24 at GCMServices.java is Sender sender = new Sender(API_KEY);

Regarding classpath, I have:

<classpathentry kind="lib" path="war/WEB-INF/lib/gcm-server.jar"/>

Which is the correct path.

What am I doing wrong?
