到分析服务的olap4j连接

Question

您好，我正在尝试通过olap4j连接到microsoft分析服务，但每次"org.olap4j.OlapException: this connection遇到一个执行查询时出现异常“时，我都会收到这个错误。

以下是对错误的完整描述：

<code>22:30:45.331 [ERROR] [kimo] 22:30:45.326:XRP4:WARN:RPCManager:org.olap4j.OlapException: This connection encountered an exception while executing a query.undefined - response: {operationId: &quot;listCubes_fetch&quot;,

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;

}

是否在IIS中为SQL Server Analysis Services设置了XML/A HTTP访问？

Configuring HTTP Access to SQL Server 2008 Analysis Services on Microsoft Windows Server 2008

您还需要在数据库中添加一个具有适当权限的角色，并将运行应用程序的用户添加到该角色中。
