无法通过java eclipse中的ssh隧道远程连接到mysql数据库

Question

我在Windows上使用Java Eclipse，并在Solaris 10上设置了Mysql。我使用过JSch，但它不允许我用root用户连接到Mysql数据库。 我收到以下错误：

Connected

实际上在这一行：

DriverManager.getConnection (url, dbuserName, dbpassword);

它给了我错误。 这是整体代码：

    package ir.mnaeimabadi.hello;

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

            }catch(Exception e){

                        } catch (SQLException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                    }
                } catch (SQLException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                if(session !=null && session.isConnected()){
                    System.out.println("Closing SSH Connection");
                    session.disconnect();
                }
            }
    }
