Als ik een dervlet probeer te gebruiken metwebmacro krijg ik "java.lang.NoClassDefFoundError"

Eigenlijk begrijp ik weinig van de error, maar ik denk fdat er iets niet klopt met de server setup..

hier gaat het mis:
[url="http://concept-q.com/servlet/HelloWorld/"]http://concept-q.com/servlet/HelloWorld/[/url]

[url="http://concept-q.com/servlet/TestServlet/"]http://concept-q.com/servlet/TestServlet/[/url] gaat wel goed (geen jar uit lib dir)
[url="http://concept-q.com/servlet/TestServletJar/"]http://concept-q.com/servlet/TestServletJar/[/url] gaat ook goed (gebruikt cos.jar uit lib dir)
