InstantDB: ClassNotFoundException:jdbc.idbDriver error


Hi everyone,
 
I installed InstantDB on my machine, but I get some errors. I think I installed it correctly because I can start DBBrowser and try out different SQL statements. Here is the thing though, I'am trying to run a sample servlet and all I get is error: java.lang.ClassNotFoundException:jdbc.idbDriver[jdbc.idbDriver].
Here is the source code of my servlet:
 
import javax.servlet.*;
import javax.servlet.http.*
import java.sql.*;
import org.enhydra.instantDB.jdbc.*; // do I need to include this?
 
/* All servlet-specific methods: doGet(), */
 
try{
    Class.forName("jdbc.idbDriver");
    String url = "jdbc:idb:C:\\InstantDB\\Examples\\sample.prp";
 
   Connection con = DriverMananger.getConnection(url);
   Statement stmnt = con.createStatement();
   String sql  = "SELECT * from import1";
 
   ResultSet res = stmnt.executeQuery(sql);
 
   /* rest of calls for bringing up results from ResultSet */
 
   }
   catch(SQLException exp){out.println(exp);}
   catch(Exception genExp){out.println("some exeption: " + genExp);}
}
}
 
and this is my autoexec.bat:

set CLASSPATH=c:\progra~1\allaire\jrun\lib\ext\servlet.jar;c:\InstantDB\Classes\id.jar;%CLASSPATH%
set PATH=C:\JDK1.2.2\bin
set IDB=C:\InstantDB
set JRE="C:\Program Files\JavaSoft\JRE\1.2"
set PATH=%JRE%\bin;%PATH%
set PATH=%IDB%\Classes;%PATH%
 
Any help is greatly appreciated.
 
thanks,
Alex
