Hi!

Help me with this sample. It don't work:

Linux Conectiva

pgjdbc2.jar

/etc/profile
JAVA_HOME="/usr/java/jsdk"
J2EE_HOME="/usr/java/j2ee"
CLASSPATH=".:$JAVA_HOME/lib:$J2EE_HOME/lib:/usr/java/jsdk/corejava/corejava.zip"
J2EE_CLASSPATH=$CLASSPATH
PATH="$PATH:$JAVA_HOME/bin:$J2EE_HOME/bin"
export JAVA_HOME J2EE_HOME CLASSPATH J2EE_CLASSPATH


import java.sql.*;
public class SQLStatement  {
    public static void main(String args[]) {
        String url = "jdbc:postgresql:javatest";
        Connection con;
        String query = "select col1 from test";
        Statement stmt;
        try {
            Class.forName("org.postgresql.Driver");
        } catch(java.lang.ClassNotFoundException e) {
            System.err.print("ClassNotFoundException: ");
            System.err.println(e.getMessage());
        }
        try {
            con = DriverManager.getConnection(url,"postgres", "postgres");

            stmt = con.createStatement();

            ResultSet rs = stmt.executeQuery(query);
            ResultSetMetaData rsmd = rs.getMetaData();
            int numberOfColumns = rsmd.getColumnCount();
            int rowCount = 1;
            while (rs.next()) {
                System.out.println("Linha " + rowCount + ":  ");
                for (int i = 1; i <= numberOfColumns; i++) {
                    System.out.print("   Coluna " + i + ":  ");
                    System.out.println(rs.getString(i));
                }
                System.out.println("");
                rowCount++;
            }
            stmt.close();
            con.close();

        } catch(SQLException ex) {
            System.err.print("SQLException: ");
            System.err.println(ex.getMessage());
        }
    }
}


Errors:
ClassNotFoundException: org/postgresql/Driver
SQLException: driver not found: jdbc:postgresql:javatest
