How to fix Saml assertion Exception (NoClassDefFoundError)

Hi guys i've created a saml assertion with opensaml-j and when i run the program an exception occurs and throws NoClassDefFoundError
i've loaded all the necessary jar files but still don't work
here's my code:

Error when trying to load sound using OpenAL in Java

I was watching this tutorial on making games using java and I was on the part where we import music to our game. However, when I try to load the sounds using a method created in this class:
package main;
import java.util.HashMap;
import java.util.Map;
import org.newdawn.slick.Music;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.Sound;
public class AudioPlayer {
public static Map<String, Sound> soundMap = new HashMap<String, Sound>();
public static Map<String, Music> musicMap = new HashMap<String, Music>();
public static void load(){
try {
soundMap.put("click_sound", new Sound("res/clickSound.ogg"));
musicMap.put("music", new Music("res/background_Music.ogg"));
} catch (SlickException e) {
e.printStackTrace();
}
}
public static Music getMusic(String key){
return musicMap.get(key);
}
public static Sound getSound(String key){
return soundMap.get(key);
}
}
i get an error that says this:

How can I solve this error in Processing using the unfoldingmaps

This is my code
import processing.core.PApplet;
import de.fhpotsdam.unfolding.UnfoldingMap;
import de.fhpotsdam.unfolding.utils.MapUtils;
public class SimpleMapApp extends PApplet {
UnfoldingMap map;
public void setup() {
size(750, 600,P2D);
map = new UnfoldingMap(this);
MapUtils.createDefaultEventDispatcher(this, map);
}
public void draw() {
map.draw();
}
}
When i run it throws exception:
Unfolding Map v0.9.6
Using OpenGLMapDisplay with processing.opengl.PGraphics2D
java.io.IOException: Server returned HTTP response code: 500 for URL:

Try changing your map provider.
map = new UnfoldingMap(this, new Google.GoogleMapProvider());

can anyone help me plz..

java.lang.VerifyError can happen if you're running against a different version of a library than the code was compiled against.
Looking in the github repository, I see the files are dated 25 April 2013. Apparently, Jetty has received an update during these last 10 months. Find the version of Jetty that was current on that date and try again.
