一旦我有了一個SQLServer的名字，我該如何在java中列出它的數據庫？

Question

我想通過Java使用osql -L命令填充網絡上SQLServer的下拉列表。用戶將選擇一個服務器並輸入用戶名和密碼。我還需要使用該服務器上的數據庫填充另一個列表。關於如何使用java實現這一點的任何想法？如果可能的話，請給java代碼。

謝謝。

public class SQL implements ActionListener{ 

public static void main(String[] args) throws Exception{ 
    String[] str = new String[] {"cmd.exe", "/c", "osql", "-L" }; 
    Runtime rt = Runtime.getRuntime(); 
    try{ 

     Process p = rt.exec(str); 
     InputStream is =p.getInputStream(); 
     InputStream err = p.getErrorStream(); 
     InputStreamReader in = new InputStreamReader(is); 

     StringBuffer sb = new StringBuffer(); 
     BufferedReader buff = new BufferedReader(in); 

     //clearing away white space and "Servers" 
     buff.readLine(); 
     buff.readLine(); 


     String line = buff.readLine(); 
     JComboBox servers = new JComboBox(); 
     while (line != null){ 
      servers.addItem(line.trim()); 
      line =buff.readLine(); 
     } 
     SQL sql = new SQL(); 

     servers.addActionListener(sql); 
     JOptionPane.showMessageDialog(null, servers); 

    }catch(Exception ex) 
    { 
     ex.printStackTrace(); 
    } 
} 


@Override 
public void actionPerformed(ActionEvent e) { 
    JComboBox cb = (JComboBox)e.getSource(); 
    String ser = (String)cb.getSelectedItem(); 


} 
}

Answer 2

public static void main(String[] args) { 
     String[] str = new String[] {"cmd.exe", "/c", "sqlcmd -U abc -P abc -q sp_databases"}; 

     Runtime rt = Runtime.getRuntime(); 
     try{ 

      String ss = null; 
      Process p = rt.exec(str); 

      BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream())); 

      BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream())); 

      //obj.exec(ss); 
      System.out.println("Here is the standard output of the command:\n"); 
      while ((ss = stdInput.readLine()) != null) { 
       System.out.println(ss); 
      } 

      System.out.println("Here is the standard error of the command (if any):\n"); 
      while ((ss = stdError.readLine()) != null) { 
       System.out.println(ss); 
      } 

     }catch(Exception ex) 
     { 
      ex.printStackTrace(); 
     } 
    }
