Обсуждение: connectivity problem
I am using postgreSQL 7.3,j2sdk1.4.2 and have
installed jdbc driver as pg73jdbc3.jar
Here is the classpath :
exportCLASSPATH=/root/j2sdk1.4.2/bin/test1.java:/root/j2sdk_nb/j2sdk1.4.2/jre/lib/ext/pg73jdbc3.jar:.
and here is the code:
import java.sql.*;
class test2{
public static void main (String args[]) {
try{
Class.forName("org.postgresql.Driver");
String
url="jdbc:postgresql//10.1.30.10:85/test";
Connection con =
DriverManager.getConnection(url, "postgres", "");
Statement stm= con.createStatement();
stm.setQueryTimeout(10);
ResultSet rs = stm.executeQuery("select col1 from
test1");
rs.next();
System.out.println(rs.getString(1));
}catch(ClassNotFoundException e) {
System.out.println("Exception");
System.out.println(e.toString());
}
catch(SQLException e) {
System.out.println("Exception");
System.out.println(e.toString());
}
}
}
and here is the error I receive :
Exception
java.sql.SQLException: No suitable driver

I also would be very surprised if 85 was the correct port to connect to. Based on your previous attempt to connct to localhost I would recommend using jdbc:postgresql://127.0.0.1/test Kris Jurka
