Bonjour,j'essaie de me connecter à une base de données SQL server à partir d'un programme java en utilisant un pilote jTDS. Voici le code java:
import java.sql.*;
import java.io.*;
import java.sql.Driver;
import javax.sql.DataSource;
import javax.sql.ConnectionPoolDataSource;
import javax.sql.XADataSource;
import javax.naming.spi.ObjectFactory;
public class Testjdbc1{
public static void main (String[] args)throws Exception{
try {
Class.forName("net.sourceforge.jtds.jdbc.Driver");
}
catch(ClassNotFoundException e){
e.printStackTrace ();
}
String url="jdbc:jtds:sqlserver://localhost:1433/ABC4;appName=jTDS";
Connection con=DriverManager.getConnection(url);
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery("SELECT id_item,type_item,type1_item,state,path,file FROM T_ITEM");
while (rs.next()){
int id=rs.getInt("id_item");
int type=rs.getInt("type_item");
int type1=rs.getInt("type1_item");
int etat=rs.getInt("state");
String chemin=rs.getString("path");
String nom=rs.getString("file");
System.out.println("le nom du fichier est: "+ nom);
}
}
}
et le message d'erreur est le suivant:
Exception in thread "main" java.sql.SQLException: Network error IOException: Connection refused: connect

... 5 more
j'ai besoin d'une astuce pour resoudre ce problème. Merci d'avance
NB: il s'agit de SQL server 7.0
