olap4j连接到分析服务

Question

你好我试图通过olap4j连接到微软的分析服务，但我得到这个错误每次“org.olap4j.OlapException：执行一个查询这方面遇到异常”

这个充满错误的描述：

<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; 

}

你有没有设置XML/IIS中为SQL Server Analysis Services中的HTTP访问？

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

您还需要添加具有相应权限数据库中的角色，并添加 正在运行的应用程序作为该角色的用户。
