Can't compile using OracleTypes.CURSOR

Question

I'm trying learn how to use Stored Procedures. My IDE is Forte 3.0 CE with Oracle 8i(8.1.6.0.0).
When I try to compile the code below I get an error:
Cannot Resolve Symbo for OracleTypes.CURSOR
If I change it to Types.VARCHAR it will compile but I get the error:
[Oracle][ODBC] Syntax error or access violation.
It seems the issue is that the OracleTypes objects are not available to me.
What do I need to do to include/import those?
Thanks very much.

OK. So I think I've found the problem but haven't got it working 100% yet.
I believe the solution is to include the classes111.zip file in the classpath. This file contains the oracle.jdbc.driver package.
The problem is I've included this in the classpath on my Windows 2000 Pro Machine (using Control Panel?system>envirnoment variables>classpath) but when I try to import the package it still can't find it.
So,if I can figure out why the classes111.zip is not being found by the compiler that should solve the problem.
