我希望使用 Java 连接到 SSAS 2012 并尝试过 olap4j 驱动程序。我在 Linux (Ubuntu 14.04) 平台上工作。

我读过 Olap4j 适用于 Windows，但它适用于 Linux 吗？

我写了一些 Java 代码，它给出了运行时错误。此错误是因为 Linux 机器无法连接到 SSAS。

我已经设置了http访问和 IIS 服务器并使用 msmdpump.dll 进行连接。

以下是Java代码和错误：

代码

package ssas;
import java.sql.Connection;
//import java.lang.*;
import java.sql.DriverManager;
import java.sql.SQLException;    

import org.olap4j.Cell;
import org.olap4j.CellSet;
import org.olap4j.OlapConnection;
import org.olap4j.OlapException;
import org.olap4j.OlapStatement;
import org.olap4j.OlapWrapper;
import org.olap4j.Position;
import org.olap4j.metadata.Member;

public class connexionSSAS
{
    public static void main(String[] args) throws ClassNotFoundException,
                                                  OlapException {

    Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");

    Connection connection = null;
    try {
        connection = DriverManager.getConnection(
            "jdbc:xmla:Server=http://01XXXXXXXX/olap/msmdpump.dll;" +
            "Catalog=sample_Cube");
    } catch (SQLException e) {
        e.printStackTrace();
    }

    if (null == connection) {
        System.out.println("Cnul");
    }

    OlapWrapper wrapper = (OlapWrapper) connection;
    OlapConnection olapConnection = null;
    try {
        olapConnection = wrapper.unwrap(OlapConnection.class);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    olapConnection.setCatalog("sample_Cube");
    OlapStatement statement = null;
    CellSet cellSet = null;        

    System.out.println(olapConnection.getCatalog());

    try {
        statement = (OlapStatement) olapConnection.createStatement();

        CellSet=statement.executeOlapQuery(
            "Summarize(FactDiagnosis,FactDiagnosis[ImportDateKey])");
        args}    
    catch(SQLException e) {
        e.printStackTrace();
    }
    }
}

错误

如果我评论包含'OlapConnection'的语句，此代码将运行。任何帮助，将不胜感激。
