Ciao a tutti,
premetto che è una settimana che ho iniziato a sviluppare in java (ho sempre lavorato in .net fino ad ora).
In pratica sto sviluppando un webservice che utilizzando il SingleSignon di SAP si connette al servizio di Xmla e mi restituisce un xml.
Per iniziare ho seguto gli esempi nei seguenti link
http://help.sap.com/javadocs/NW04s/c...al_1.java.html
http://help.sap.com/javadocs/NW04/cu...pers.java.html

ma in entrambi i casi ho il seguente errore

questo errore viene generato rispettivamente alle seguenti righe

ManagedConnectionFactory mcf = new XmlaManagedConnectionFactory();
e
ManagedConnectionFactory mcf = (ManagedConnectionFactory) Class.forName("com.sap.ip.bi.sdk.dac.connector.xml a.XmlaManagedConnectionFactory").newInstance();

le righe di codice fanno praticamente lo stesso lavoro e non riesco a capire quale sia il problema..
Grazie
