[JAVA] Apache XML-RPC, java.lang.NoClassDefFoundError

[sanderdam]

Voor een DVD-organiser programma probeer ik Moviemeter Api met XML-RPC in mijn java-code te implementeren.

Dit programeer ik in NetBeans. Helaas krijg ik de volgende fout.

code:

Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/apache/ws/commons/serialize/DOMSerializer

De volgende code heb ik nu:

Java:

import java.net.MalformedURLException;
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.apache.xmlrpc.XmlRpcException;
import org.apache.xmlrpc.client.*;


/**

public class SearchManager {

    private String sessionkey;
    private XmlRpcClient client;
    private XmlRpcClientConfigImpl config;
    private String apikey;
    String AppName = "DVD Explorer";
    String Email = "onzichtbaar";

    public SearchManager() {

        client = new XmlRpcClient();
        config = new XmlRpcClientConfigImpl();
        try {
            config.setServerURL(new URL("http://www.moviemeter.nl/ws"));
        } catch (MalformedURLException ex) {
            Logger.getLogger(SearchManager.class.getName()).log(Level.SEVERE, null, ex);
        }
        client.setConfig(config);
    }

    public void startSession() {

        Object[] params = {"4sdqrgp9bkxez2c6ua59fcupnf9k6hfz"};
        try {
            Object response = client.execute("api.startSession", params);
        } catch (XmlRpcException ex) {
            Logger.getLogger(SearchManager.class.getName()).log(Level.SEVERE, null, ex);
        }
        }

De genoemde fout komt al in werking in de constructor, bij client = new XmlRpcClient();

Ik gebruik de volgende libraries:

• xmlrpc-client-3.1.2.jar
• xmlrpc-common-3.1.2.jar
• commons-codec-1.3.jar
• commons-httpclient-2.0.2.jar
• commons-logging.jar

Deze zijn als Class Libraries toegevoegd aan NetBeans en daarna aan het project.

Weet iemand wat ik verkeerd doe en kan die mij in de goede richting zetten?

Als je zoekt met advanced search en class search op "org.apache.ws.commons.serialize.DOMSerializer" zul je zien dat je org.apache.ws.commons.util:ws-commons-util:1.0.2 mist. Die kun je daar ook downloaden. Dat is namelijk een dependency van xmlrpc-common.
