Oh dear - probably missing imports or something in your code.
Maybe try running a standalone java program from the command line (see
below), as thats what I used to check this:
$ export CLASSPAT=path-to-your-postgresql.jar:.
$ java test1
---- test1.java ---
import java.sql.*;
import java.util.*;
public class test1 {
public static void main( String args[] ) throws Exception {
Class.forName("org.postgresql.Driver");
String url =
"jdbc:postgresql://localhost:5432/postgres?user=postgres&password=major";
Properties props = new Properties();
props.setProperty("loglevel","2");
Connection conn = DriverManager.getConnection(url, props);
System.out.println( "Connected to: " + url );
conn.close ();
}
}
