connection xmla / data source null

[allodren]

 Hello world !

I search on forums many way to understand my problem but didn't solutions.

I know that a lot of people are faced to this matter <em></em> :

I TRY TO EDIT A CUBE FROM MONDRIAN TO JASPER SERVER.

I define the mondrian connection, the data source (XMLA), the schema, the xmla.

And then when I lunch my cube on the repertory, Analysis view : IT tells : 

Code:

com.jaspersoft.jasperserver.api.JSException: com.tonbeller.jpivot.olap.model.OlapException: Mondrian Error:Internal error: no data source is configured with name 'Provider=Mondrian;DataSource=casource;'[/code]

I don't understand because the datasource name is well configured !
My adress is : http://localhost:8080/jasperserver/xmla
The catalog is the name of my schema in Mondrian.

Please Help me if you can ! <em></em>

 Okay ! Now I find the good catalog and datasource. But the new problem is when I start the analysis view, the server say :

com.jaspersoft.jasperserver.api.JSException: com.tonbeller.jpivot.olap.model.OlapException: java.lang.NullPointerException

Do you know this ? What does it mean ?
