Witam, podczas próby połączenia z bazą danych wyskakuje mi taki błąd:

W czym tkwi problem?

Nie załadował Ci klasy:
java.lang.ClassNotFoundException: com.sybase.jdbc3.jdbc.SybDataSource

na razie tyle, bo dawno w javie nie pisałem ;]

teraz mam taki problem:

BUILD SUCCESSFUL (total time: 10 seconds)

Chciałbym połączyć się z moją bazą stworzona na serwerze Microsoft Sql Serwer, używam takiego kodu:

Connection connection = null;
try
{
// the sql server driver string
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

  // the sql server url
  String url = "jdbc:microsoft:sqlserver:*localhost:1433;DatabaseName=asd"; * tutaj wszystko ok?

  // get the sql server database connection
  connection = DriverManager.getConnection(url,"dba", "sql");

  // now do whatever you want to do with the connection
  // ...

}
catch (ClassNotFoundException e)
{
  e.printStackTrace();
  System.exit(1);
}
catch (SQLException e)
{
  e.printStackTrace();
  System.exit(2);
}

Robię to po raz pierwszy więc proszę o pomoc. Ściągnąłem sterownik jdbc, wystarczy go zainstalować czy też trzeba jakies referencje dodawać w javie?

wystarczy go wgrać do odpowiedniego katalogu do którego jest ustawiona odpowiednio ścieżka dostępu.
Oczywiście w MSSQL musisz mieć założoną bazę i użytkownika ze stosownymi uprawnieniami. Z kodu który podałeś wynika ze Twoja baza nazywa się asd a użytkownik to dba hasło to sql.

Wyświetla mi teraz taki błąd:

Proszę o radę co z tym zrobić.

już naprawione, przepraszam za offtopic.

Oto mój kod:

import java.sql.*;
import com.microsoft.jdbc.sqlserver.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

/**
  * Microsoft SQL Server JDBC test program
  */
public class Test {
  public Test() throws Exception {
    // Get connection
    DriverManager.registerDriver(new
    com.microsoft.jdbc.sqlserver.SQLServerDriver());
    Connection connection = DriverManager.getConnection(
    "jdbc:microsoft:sqlserver://localhost:1433","dba","sql");
    if (connection != null) {
     System.out.println();
      System.out.println("Successfully connected");
      System.out.println();
      // Meta data
      DatabaseMetaData meta = connection.getMetaData();
      System.out.println("\nDriver Information");
      System.out.println("Driver Name: "
       + meta.getDriverName());
      System.out.println("Driver Version: "
       + meta.getDriverVersion());
      System.out.println("\nDatabase Information ");
      System.out.println("Database Name: "
       + meta.getDatabaseProductName());
      System.out.println("Database Version: "+
      meta.getDatabaseProductVersion());
    }
 } // Test
 public static void main (String args[]) throws Exception {
  Test test = new Test();
 }
}

Co z tym fantem zrobić?

Rozumiem ze przerasta cię wpisanie błędu w google? o_O

Na moje oko to nie postawiałeś MSSQL odpowiednio (tak, trzeba pewne opcje ustawić...) albo podałeś złe dane podczas łaczenia się z przez JDBC.
Spróbuj tak: (jeśli user i pass są poprawne i w ustawieniach MSSQL umożliwiłeś łączenie się z tym użytkownikiem!)

Connection connection = DriverManager.getConnection("jdbc:sqlserver://localhost","dba","sql");
