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:

java.lang.ClassNotFoundException: org.postgresql.Driver
