Re: Postgresql-JDBC connectivity - Mailing list pgsql-jdbc

I set the classpath, copied in the lib folder of web-inf. If I try to
run a simple java program shown below:
import java.sql.*;

public class Example1
{
public static void main(String[] argv)
{
   System.out.println("Checking if Driver is registerd");
   try
   {
   Class.forName("org.postgresql.Driver");
   }
   catch(ClassNotFoundException cnfe)
   {
   System.out.println("Couldn't find the Driver");
   cnfe.printStackTrace();
   System.exit(1);
   }
   System.out.println("registered the Driver OK, so lets make a
connection");
   Connection c = null;
     try
   {
   c=
DriverManager.getConnection("jdbc:postgresql://localhost/trainneedcorp","postgres","admin");

   }
   catch(SQLException se)
   {
   System.out.println("Couldnt connect");
   se.printStackTrace();
   System.exit(1);
   }
   if(c != null)
   System.out.println("WE CONNECTED");
   else
   System.out.println("Reaching here is not done");
   }
   }
   I get the following error:
