我们正在尝试使用 olap4j 针对 SSAS 运行 OLAP 查询。我设法设置了 XML/A 端点，SSMS 正确连接到端点并且工作正常。
但是，每次我尝试从 JAVA 运行查询时都会失败。
Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");
Connection connection = DriverManager.getConnection(
"jdbc:xmla:Server=http://servername/msmdpump.dll;Catalog=DatabaseName");
OlapWrapper wrapper = (OlapWrapper) connection;
OlapConnection olapConnection = wrapper.unwrap(OlapConnection.class);
CellSet set = olapConnection.createStatement().executeOlapQuery(
"SELECT [Measures].[Foo] ON COLUMNS, " +
"[Dimension].[Id].[All].children ON ROWS FROM [Cube]");
异常/堆栈跟踪：
