this is the connection function 

<code>

    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;

}

Solution

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.
