public static OlapConnection getConnectionAServices() throws Exception {
Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");
// anonymous connection
Connection connectionXMLA = DriverManager.getConnection(
"jdbc:xmla:Server=http://localhost/olap/msmdpump.dll;" + "Catalog=Analysis_Service;");
OlapWrapper wrapper = (OlapWrapper) connectionXMLA;
OlapConnection olapConnection = wrapper.unwrap(OlapConnection.class);
return olapConnection;
}

Have you set up XML/A HTTP access for SQL Server Analysis Services in IIS?
Configuring HTTP Access to SQL Server 2008 Analysis Services on Microsoft Windows Server 2008
You also need to add a role in the database with appropriate permissions, and to add
the user you are running the application as to that role.
