一旦我有了一个SQLServer的名字,我该如何在Java中列出它的数据库?

database sql java

我正在尝试使用 osql -L 通过Java命令。然后,用户将选择一个服务器并输入用户名和密码。我还需要用该服务器上的数据库填充另一个列表。关于如何使用Java实现这一点有什么想法吗?如果可能的话,请给出Java代码。

谢谢您。

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();


}
}
