ClientAuthentication example java.lang.NoClassDefFoundError

Hi,

i tried the example ClientAuthentication, but the example throws an 
exception:

run:
Exception in thread "main" java.lang.NoClassDefFoundError: 
org/apache/commons/logging/LogFactory
         at

         at 
org.apache.http.examples.client.ClientAuthentication.main(ClientAuthentication.java:28)

         ... 3 more
Java Result: 1
ERSTELLEN ERFOLGREICH (Gesamtzeit: 0 Minuten 0 Sekunden)


The class org.apache.commons.logging.LogFactory is not found at this line:

DefaultHttpClient httpclient = new DefaultHttpClient();

I looked into the source code, but i did not find any logger definition.

Any hints?

regards
Andreas
